GIMP: the free, open-source Photoshop alternative
GIMP is a free, open-source image editor that handles most Photoshop tasks. This guide covers what it does well, how to install it safely, and where to start.
GIMP (the GNU Image Manipulation Program) is a free, open-source image editor for Windows, macOS, and Linux that covers most of what people open Photoshop to do: retouching, compositing, layered edits, and exporting to common file formats. It won’t replace Photoshop for every print or studio workflow, but for hobbyists, students, and anyone who would rather not pay a subscription, it is a genuinely capable tool. You can download it from the official site, learn a handful of basics, and start editing the same day.
What GIMP is, and who it suits
GIMP calls itself “The Free & Open Source Image Editor,” and that is the honest description. It is free software released under the GPLv3, which means it costs nothing and its source code is open. The same program runs on GNU/Linux, macOS, and Windows.
It is built for real image work, not just cropping and filters: photo retouching and restoration, creative composites, original artwork, and design elements like icons and interface art. It is also scriptable through languages including Python and Scheme, so repetitive edits can be automated, and the community has published a large library of plug-ins and scripts.
GIMP fits you well if you edit occasionally, work on Linux, or simply want to avoid a monthly fee. If you only need quick touch-ups, resizing, and batch edits without a learning curve, a lighter tool like PhotoScape for Windows may be all you need.
How it compares to Photoshop, honestly
GIMP matches Photoshop on the fundamentals most people use every day: layers and masks, selection tools, brushes, clone and heal retouching, curves and levels, filters, and export to formats like JPEG, PNG, and PDF. The interface is different, but the concepts carry over.
Where Photoshop still leads is professional print production, where its CMYK and color tooling is more complete; teams whose files must stay perfectly interchangeable in Photoshop’s native format; and the sheer size of its paid plug-in and training ecosystem. If your work depends on those, GIMP will feel like a compromise. For most personal and small-project editing, it does not.
| Factor | GIMP | Photoshop |
|---|---|---|
| Price | Free, open source (GPLv3) | Paid Adobe subscription |
| Platforms | Windows, macOS, Linux | Windows, macOS |
| Native file format | XCF | PSD |
| Opening PSD files | Opens and exports .psd; not every feature converts exactly | Native |
| CMYK / print output | Possible, but takes extra setup | Built in, industry standard |
| Extending it | Python and Scheme scripts, community plug-ins | Large paid plug-in ecosystem |
| Learning material | Free official and community tutorials | Vast, much of it paid |
Download it safely from the official site
Get GIMP only from gimp.org or the mirrors listed on its official downloads page. Builds are offered for Windows, macOS (Intel and Apple Silicon), and Linux, plus the source code. Every binary comes with a published SHA256 checksum and a VirusTotal link so you can confirm the file you downloaded is intact and untampered.
Be wary of anything labeled “GIMP” that comes from somewhere else. The project notes that it does not publish a package on Apple’s App Store, so store listings are third-party and not connected to the GIMP team. The same caution applies to download portals that wrap the installer in extra “offers.” Skipping those keeps junk and bundled software off your machine. The install itself is modest, so if your drive is tight, it helps to first free up space on Windows 11.
First things to know once it is open
GIMP opens in a single window by default. If you prefer separate floating panels, you switch to multi-window mode by unchecking Windows > Single-Window Mode in the main menu. The Toolbox is where the tools live, and the Layers dialog is one you will want visible at all times; docked dialogs stack as tabs so you can keep layers, channels, and paths together.
A few basics get you moving:
- Layers and masks let you stack and blend edits without touching the original pixels.
- Selection tools (rectangle, free, fuzzy, and by color) isolate the part of the image you want to change.
- Paintbrush, pencil, eraser, clone, and heal handle painting and retouching.
- Crop, transform, text, and color picker cover the everyday adjustments.
When you open a JPEG or PNG, GIMP imports it into its own XCF project format. XCF is the only format that stores everything about your edit, so save your working file as XCF and export a copy when you need a JPEG or PNG. GIMP can open Photoshop .psd files and export back to .psd too, which is handy when someone hands you a layered file. Do not expect a perfect round trip, though: as the manual puts it, “not all blending modes can be converted to an exact equivalent between GIMP and Photoshop.” If GIMP ever feels sluggish on an older machine, the fixes in why a Windows PC runs slow apply here as much as anywhere.
Free ways to learn GIMP
You do not need a paid course. The project’s own GIMP tutorials include beginner walkthroughs (the “GIMP Quickies” set is a good start) plus photo-editing and painting guides. For the full reference, the official user manual documents every tool and menu. Between those two, most questions have an answer written by the people who build the software.
Start small: open a photo, try a non-destructive edit on a duplicate layer, and export a copy. Once layers, masks, and selections click, the rest of GIMP opens up, and you will have a full-featured editor that cost nothing.
