Current Stable Version

The current stable release of GIMP is 2.10.22 (2020-10-04).

We think your OS is Well, we don't actually know. Either JavaScript is disabled, or I am not working quite right.. So I am showing you all the options.

GIMP for Unix-like systems

If available, the official package from your Unix-like distribution is the recommended method of installing GIMP!

The flatpak build is new and has known limitations, though it will likely provide faster updates, following GIMP releases closely.
Therefore choose your installation medium according to your needs.

Flatpak build available in: i386, x86-64, ARM and AArch64.

Flatpak additional instructions

The flatpak link above should open your software installer and prompt you to install GIMP. Yet it may not work out-of-the-box on some platforms since the flatpak technology is new. If that is the case, ensure flatpak is installed and if clicking the link still does not prompt to install GIMP, then manually install by command line:

flatpak install https://flathub.org/repo/appstream/org.gimp.GIMP.flatpakref

Once installed, it will be made available exactly the same way as other applications (menus, desktop overview, or any specific application launch process used by your desktop).
If this is not the case, we suggest to report a bug to your desktop or distribution asking for proper support of flatpak. In the meantime, you can still run it by command line (not as the recommended method, only a workaround):

flatpak run org.gimp.GIMP//stable

This installation will also provide regular update. You don't have to come back on this page and install again (it will not work!) when a new version of GIMP is released. Instead if your distribution and/or desktop has a good support for flatpak, it should propose to perform updates.
Once again, if your distribution does not have proper support, you can always fall back to using the following command line:

flatpak update

Systems without flatpak support

GIMP can also run on Solaris and is available for the BSD family of systems such as FreeBSD and OpenBSD.

Please refer to the documentation for your Unix-like system on the installation of software.

GIMP for macOS

Note: the currently available package provides GIMP 2.10.14 and has not yet updated to the latest version, GIMP 2.10.22. We're working on that, please check back later.

Download apache web server for mac. Click on the link above to download ApacheDS for Mac OS X. Your download appears in the download manager of your web browser. Double-click on the disk image to open it. It may have already been opened by your web browser.

The download links above will attempt to download GIMP from one of our trusted mirror servers. If the mirrors do not work or you would rather download directly from our server, you can get the direct download here.

Supported OS: macOS 10.9 Mavericks or over

Since the 2.8.2 version, GIMP runs on OSX natively. No X11 environment is required.

Native build

The official GIMP 2.10 DMG installer (linked above) is a stock GIMP build without any add-ons. Just open the downloaded DMG and drag and drop GIMP into your 'Applications' folder.

The SHA256 hash sum for gimp-2.10.14-x86_64-1.dmg is: 52654d85f894834f6c134c724beff3eddf212a1bda317299314322cfeff97e52

Check it on VirusTotal: gimp-2.10.14-x86_64-1.dmg

Older Downloads

Previous installers for OSX can be found here: download.gimp.org.

Macports

An easy way to compile and install GIMP and other great Free software on your Mac is by using Macports. The installer allows you to choose from a large directory of packages. To install gimp using Macports, you simply do sudo port install gimp once you have Macports installed.

Last we checked, the GIMP port file pointed to the current stable release and we have reports from people who've built GIMP successfully this way.

Homebrew

Homebrew is similar to Macports and provides packages (aka formulas) to install, either by compiling them from source or by using pre-made binaries. There are indications that there is now a formula for GIMP, installable with: brew tap homebrew/cask && brew cask install gimp.

NOTE! Please be aware that it was announced recently that Homebrew is using analytics. To turn this off in homebrew then run: brew analytics off
You can read more about this on Brew Analytics.

Fink

Fink is a package repository that offer mostly precompiled binaries. It provides the apt-get command known to e.g. Debian and Ubuntu users, and installing GIMP is as easy as sudo apt-get install gimp once you have installed the Fink installer.
If there's no binary package, then fink install gimp will compile GIMP from source.

Disclaimer: we haven't been able to determine if it is possible to install or build recent GIMP from Fink. Last we checked, GIMP 2.6.12 appears to be the most recent GIMP package that is offered there.

GIMP for Windows

Supported OS: Windows 7 or over

These links download the official GIMP installer for Windows (~200 MB). The installer contains both 32-bit and 64-bit versions of GIMP, and will automatically use the appropriate one.

17 March 2020 - Release 3.1.9.7

Windows

Changed the behavior of the “X-Y plot for a range of values” which allowed plotting graphs after changing input parameters in the main window without hitting the “Calculate” button which, however, is required to update the “X-Y plot for a range of values” with the new input parameters from the main dialog.

21 February 2020 - Release 3.1.9.6

Mac and Windows

Fixed a bug in z tests: Generic z test: Analysis: Criterion: Compute alpha: The critical z was calculated incorrectly.

Fixed a bug in t tests: Linear bivariate regression: One group, size of slope: |sy/sx| was sometimes calculated inccorrecty.

14 January 2020 - Release 3.1.9.5

Mac

Fixed a bug that caused the “Options” button (which is available for some tests in the main window) to disappear when “Hide distributions & control” was selected.

6 February 2019 - Release 3.1.9.4

Mac and Windows

7 July 2017 - Release 3.1.9.3

Mac

Fixed a bug that could cause crashes.

28 March 2014 - Release 3.1.9.2

Mac

Fixed a bug in the χ² tests: Goodness-of-fit tests: Contingency tables module which prevented the computed effect size from appearing in the effect size drawer.

Windows

Fixed a bug that could occur under very specific circumstances when transferring an effect size from the effect size drawer to the main window.

10 March 2014 - Release 3.1.9.1

G++ On Mac

Mac

Now includes the calculator that previously has been included only in the Windows version.

4 February 2014 - Release 3.1.9

Mac and Windows

Fixed a bug in the sign test’s sensitivity analysis which led to an offset of -0.5 in the reported effect size.
Changed the behaviour of all tests based on the binomial distribution. The upper and lower limits are now always within the range [0,n] instead of [-1,n+1]. This change may lead to alpha values larger than the requested alpha values, but now we have the advantage that the upper and lower limits correspond to actual decision boundaries. For instance, in a two-sided test H0 is rejected if, for the observed number x of successes, it holds that x <= lower limit or x >= upper limit. Note, however, that the change affects the results only when N is very small.

31 January 2014 - Release 3.1.8

Mac and Windows

Improvements in the logistic regression module: (1) improved numerical stability (in particular for lognormal distributed covariates); (2) additional validity checks for input parameters (this applies also to the poisson regression module); (3) in sensitivity analyses the handling of cases in which the power does not increase monotonically with effect size is improved: an additional Actual power output field has been added; a deviation of this actual power value from the one requested on the input side indicates such cases; it is recommended that you check how the power depends on the effect size in the plot window.

19 April 2013 - Release 3.1.7

Mac and Windows

Fixed a problem in the exact test of Proportions: Inequality, two independent groups (uncontional). The problem only occurred when p1 > p2.

18 Frebruary 2013 - Release 3.1.6

Mac and Windows

Fixed a problem in the sensitivity analysis of the logistic regression. The problem only occurred when p2 >= p1.

Mac

Fixed a problem in Fisher’s exact test.

12 September 2012 - Release 3.1.5.1

Mac

Fixed a problem with the effect size drawers of ANOVA: Fixed effects. The drawers now appear correctly after clicking on the Determine button.

20 August 2012 - Release 3.1.5

Mac and Windows

Fixed a problem in the test of equality of two variances. The problem did not occur when both sample sizes were identical.
Fixed a problem in calculating the effect size from variances in the repeated measures ANOVA.

3 July 2012 - Release 3.1.4

Mac and Windows

Added an options dialog to the repeated-measures ANOVA which allows a more flexible specification of effect sizes.
Fixed a problem in calculating the sample size for Fisher's exact test. The problem did not occur with post hoc analyses.

22 June 2011 - Release 3.1.3

Mac and Windows

Fixed a bug in the ANCOVA module. Changing the number of covariates now correctly leads to the appropriate change in the denominator degrees of freedom.

5 January 2010 - Release 3.1.2

Mac and Windows

Renamed the Repetitions parameter in repeated measures procedures to Number of measurements (Repetitions was misleading because it incorrectly suggested that the first measurement would not be counted).
Fixed a problem in the sensitivity analysis of the logistic regression procedure: There was an error if Odds ratio was chosen as the effect size. The problem did not occur when the effect size was specified in terms of Two probabilities.

Mac

The Window menu now contains the option to hide the distributions plot and the protocol section (Hide distributions & protocol menu item) so that G*Power can be accommodated to small screens. This option has been available for some time in the Windows version (see View menu).

16 December 2009 - Release 3.1

Mac

Added procedures to analyze the power of tests for single correlations based on the tetrachoric model, comparisons of dependent correlations, bivariate linear regression, multiple linear regression based on the random predictor model, logistic regression, and Poisson regression.

08 December 2009 - Release 3.1.1

Windows

Re-enabled options dialog for Correlation: Bivariate normal model.

29 June 2009 - Release 3.1

Windows

Added procedures to analyze the power of tests referring to single correlations based on the tetrachoric model, comparisons of dependent correlations, bivariate linear regression, multiple linear regression based on the random predictor model, logistic regression, and Poisson regression.

24 January 2008 - Release 3.0.10

Mac and Windows

Fixed a problem in the X-Y plot for a range of values for Generic F tests. The degrees of freedom were not properly set in the graph, leading to erroneous plot values.

22 January 2008 - Release 3.0.9

Mac

Eliminated the brushed metal look for better readability under Mac OS X 10.5.

Windows

Fixed some minor GUI problems (buttons had German titles; button in file dialog named “open” instead of “save”).
Fixed problems with distribution plots (plots were sometimes not appropriately clipped when copied or saved as metafile; drawing glitches with some very steep curves).
The file dialog shown when saving graphs or protocols now uses the user's home directory (myDocuments) as defaults directory.

10 October 2007 - Release 3.0.8

Mac and Windows

Fixed a serious bug in the CDF routine of the noncentral t distribution introduced in the bugfix release 3.0.7. Please update immediately if you installed version 3.0.7.

8 October 2007 - Release 3.0.7

Mac and Windows

Fixed a bug in the function calculating the CDF of the noncentral t-distribution that occasionally led to (obviously) wrong values when p was very close to 1. All power routines based on the t distribution were affected by this bug.

14 August 2007 - Release 3.0.6

Download G Power For Mac

Mac

Fixed a bug in the routine that draws the central and noncentral t distributions for two-tailed tests. When alpha was very small, this bug could cause G*Power to crash.

03 July 2007 - Release 3.0.5

Mac and Windows

Fixed a bug in the Power Plot (opened using the X-Y-plot for a range of values button) for F tests, MANOVA: Global effects and F Tests, MANOVA: Special effects and interactions. Sometimes some of the variables were not correctly set in the plot procedure which led to erroneous values in the graphs and the associated tables.

26 June 2007 - Release 3.0.4

Mac and Windows

Fixed a bug in the Power Plot (opened using the X-Y-plot for a range of values button) for F Tests, Multiple Regression: Special (R2 increase). The numerator df value was not always correctly determined in the plot procedure which led to erroneous values in the graphs and the associated tables.
Fixed some minor problems with t tests. G•Power now checkes for invalid null effect sizes in a priori analyses. The t distribution PDF routine is now more robust for very large degrees of freedom by explicitly using a normal approximation in these cases.
When the Power Plot window was first opened by pressing the X-Y plot for a range of values button, the default was to show 4 plots simultaneously. The default has been changed to 1 plot.
Corrected some parsing errors in the calculator (in the Mac version, this only concerns text input in normal input fields).
Corrected a label in the effect size drawer for ANOVA: Fixed effects, omnibus, one-way. In the From variance input mode, the Variance within group field was erroneously labeled Error variance.

Windows

Fixed a problem with moving the main window when the effect size drawer is open. Sometimes the mouse pointer appeared to be 'glued' to the window and the movement could not be stopped properly.

1 March 2007 - Release 3.0.3

Mac and Windows:

Fixed a bug in the X-Y plots for a range of values for F Tests, ANOVA: Fixed effects, special, main effects and interactions. The df1 value was not always correctly determined in the plot procedure which led to erroneous values in the plots.
Fixed the problem in the plot procedure that (due to rounding errors) the last point on the x-axis was sometimes not included in the plot.

28 February 2007 - Release 3.0.2

Mac and Windows

Fixed a probem with tooltips for effect size conventions which were not always shown.

Windows

Added options mainly intended to make G*Power usable with low resolution displays (800 x 600 pixels)
The distribution/protocol view and the test/analysis selection view in the main window can be hidden temporarily to save space. To hide/show these sub-views press F4 (plot/protocol) and F5 (test/analysis), respectively, while the main window is active. There are also corresponding entries in the View menu.
The Graph window can now be made resizable. To do this choose 'Resizable Window' in the View menu of the Graph window. Besides enabling (restricted) resizability this option initially shrinks the window to a size that fits into a 800 x 600 screen. Deselecting the option restores the Graph window to the fixed size for which G*Power was optimized.

Mac

Download G Drive For Mac

Fixed a cosmetic problem when drawing “extreme” central and non-central distributions.

15 January 2007 - Release 3.0.1

Windows

Mac Os Download For Windows

Effect size calculation for t Tests, Difference between two indepent means (two groups), case n1 = n2: The wrong means—those of case n1 ≠ n2—were used to calcultate the effect size. This problem has been fixed.
Minor cosmetic changes.
New Readme file.
Updated installation instruction.

12.01.2007 - First release of version 3.0.0

Axel Buchner, Edgar Erdfelder, Franz Faul, Albert-Georg Lang
