Open Source Photoshop Alternatives

Best Open Source Photoshop Alternatives in 2026

Looking for the best open source Photoshop alternatives? Several free image editing tools offer powerful features for photo retouching, graphic design, digital painting, and image manipulation without expensive subscriptions.

What Is an Open Source Photoshop Alternative?

An open source Photoshop alternative is an image editing tool that has:

• Similar features to Adobe Photoshop
• Source code publicly available for use, modification, and distribution under its license.

1. Top Open Source Photoshop Alternatives

These programs are designed to do exactly what Photoshop does: edit pixel-based images (photos, digital paintings, textures). They are free to download and modify.

GIMP

GIMP is one of the best free Photoshop alternatives for advanced photo editing, image manipulation, layers, masks, and custom plugins.

• Platform: Win, Mac, Linux
• Overview: GIMP is the undisputed heavyweight champion of open-source photo editing. It has been in development for over 25 years and is the most direct feature-for-feature competitor to Photoshop.
• Key Features: Full suite of painting tools, color correction, cloning, selection, and enhancement. It supports layers, masks, and has a vast library of plugins. It now supports CMYK (with a plugin) and has a customizable interface that can be made to look very similar to Photoshop.
• Best For: Photographers, graphic designers, and anyone needing a powerful, free image editor on Windows, macOS, and Linux.
• Downside: The user interface (historically) has a steeper learning curve than Photoshop, though modern versions have improved this significantly.
• License: GNU General Public License, version 3 or later (GPLv3+).

ImageFlow

ImageFlow is a browser-based, AI-integrated editor. It provides an interface highly similar to Photoshop that runs inside a standard web tab, complete with AI selection tools.

• Platform: Web Browser (Runs on Windows, macOS, Linux, and ChromeOS via standard web browsers).
• Overview: Imageflow is a highly responsive, browser-based photo editor designed specifically to mirror the layout, keyboard shortcuts, and core layer mechanics of Adobe Photoshop. It integrates client-side AI processing directly into the workspace to simplify complex workflows without needing a high-end desktop computer.
• Key Features: Automatic on-device AI selection and background removal, a highly authentic Photoshop-style interface, layer masks, adjustment layers, and robust brush engines that process locally in your browser sandbox.
• Best For: Graphic designers, photo editors, and hobbyists looking for a stable, subscription-free Photoshop alternative that requires zero local installation.
• Downside: Because it is entirely web-based, performance heavily depends on your browser’s RAM allocation, and it lacks deeply advanced native desktop features like local plugin ecosystems or extensive script automation.
• License: GNU Affero General Public License v3 (AGPLv3), with commercial dual-licensing options available.

Photocraft

PhotoCraft is a newly released, free, open-source Adobe Photoshop alternative written entirely from scratch in Rust. It was built by software engineer Brandon Thomas using the Anthropic Claude 5.5 Opus AI model as part of a larger project called ArtCraft, which aims to recreate seven major Adobe Creative Cloud applications to escape predatory SaaS subscription models.

• Platform: macOS, Windows, Linux, FreeBSD, and web browsers.
• Overview: A free, open-source Photoshop alternative written from scratch in Rust to bypass subscription software models.
• Key Features: Despite being an alpha build, it already features native support for layers, masks, adjustment layers, layer styles, vectors, and text. It is a “clean-room” reimplementation that includes native .psd and .psb file compatibility, meaning it can open and save Photoshop files directly. It has an MCP server allowing an AI agent to open images, apply filters, edit layers, or execute complex editing workflows using code and automation scripts instead of human mouse clicks.
• Downside: The software is currently in early alpha. It is an impressive showcase of “vibe coding” and AI generation, but early users note that it still suffers from performance bugs, truncated menus, and slow brush speeds. It is not yet stable enough for professional client work or tight deadlines.
• License: dual-licensed under the MIT License or the Apache License

Krita

Krita is ideal for digital artists, illustrators, and concept designers who need professional painting tools and customizable brushes.

• Platform: Win, Mac, Linux
• Overview: While GIMP is for photo editing, Krita is built primarily for digital painting and 2D animation. However, its feature set overlaps significantly with Photoshop, making it a strong alternative for artists.
• Key Features: An incredible array of brush engines, a customizable brush stabilizer, vector tools, wrap-around mode for seamless textures, and full support for PSD files.
• Best For: Concept artists, illustrators, and comic book artists.
• Downside: Less ideal for “destructive” photo editing (like heavy retouching or complex compositing) compared to GIMP.
• License: GNU General Public License, version 3 or later (GPLv3+).

2. Alternatives for Specific Tasks

These open-source tools are not general photo editors but excel at specific workflows that are often handled in Photoshop.

Darktable

Darktable is a free, open-source photography workflow application and RAW image developer designed as a virtual lighttable and darkroom for photographers.

• Platform: Win, Mac, Linux
• Alternative to: Adobe Lightroom
• Overview: Darktable manages your digital negatives (RAW files) in a database and lets you perform non-destructive editing.
• Key Features: Professional-grade color management, non-destructive editing stack, tethered shooting, and powerful export options.
• Best For: Photographers who need a complete workflow for organizing, culling, and processing thousands of RAW images.
• License: GNU General Public License, version 3 or later (GPLv3+).

Inkscape

Inkscape is a free, open-source vector graphics editor used to create and edit two-dimensional scalable vector graphics (SVG).

• Platform: Win, Mac, Linux
• Alternative to: Adobe Illustrator
• Overview: Inkscape is a vector graphics editor, not a raster editor. While you can import photos into Inkscape, its strength lies in creating scalable graphics like logos, icons, and typography.
• Key Features: Complex path manipulation, node editing, Bézier curves, text on path, and support for the SVG format.
• Best For: Graphic designers, logo creators, and web designers who work with vector art.
• License: GNU General Public License, version 3 or later (GPLv3+).

GNU General Public License

GIMP, Inkscape, Krita and Darktable license is GNU General Public License, version 3 or later (GPLv3+) which is the most common modern “strong copyleft” open-source license. This provides very broad freedoms:

• Commercial Use: You are free to use GIMP and Inkscape for professional work, even if you are making a profit.
• Distribution: You are free to redistribute the software freely, including giving copies to friends or colleagues.
• Modification: You have the right to access the source code and change anything you want.
• Redistribution of Modifications: If you modify the code and then distribute (share or sell) that modified version, you must also make the source code for your modified version available under the same GPL license. You cannot take their code, modify it, make it proprietary (closed source), and sell it.

MIT/Apache 2.0 Dual-License

Photocraft license is MIT/Apache 2.0 dual-license that allows you to use, modify, and distribute PhotoCraft for commercial projects with no restrictions.

• Commercial Use: You are free to use PhotoCraft for professional work, client projects, and commercial artwork, even if you are making a profit.
• Distribution: You are free to redistribute the software freely, including sharing copies with colleagues or embedding it into other software packages.
• Modification: You have the right to access the source code, modify it entirely from scratch, or incorporate parts of it into your own programs.
• Redistribution of Modifications: If you modify the code and distribute (share or sell) that modified version, you are not required to make your source code public. You can legally take their code, modify it, turn it into a private, proprietary (closed-source) commercial product, and sell it without sharing your changes.

Unlike GNU/GPL software (which forces you to open-source your modifications), MIT/Apache permits you to integrate the code into closed-source, proprietary, or commercial software without being legally required to share your changes.

These alternatives can be free (Photopea, Mockofun, Affinity Photo, etc.), paid (Pixelmator Pro), proprietary, or open source (GIMP, Krita, PhotoCraft).

Open source Photoshop alternatives in comparison with proprietary software (privately owned, closed-source software), make their source code available under licenses that allow users to inspect, modify, and redistribute it under specified conditions.

Tools such as GIMP and Krita offer free, community-driven alternatives, while proprietary options may provide different interfaces, workflows, or premium features. The main difference is not simply price: it is software freedom, customization, licensing, and control. The best choice depends on your editing needs, budget, compatibility requirements, and preferred workflow.

Why Choose Open Source Image Editing Software?
