GIMP vs Affinity by Canva
Both are free/open-source alternatives to Adobe Photoshop. Here's how they stack up — verified facts, no spin.
GIMP
TOP PICKThe long-standing open-source image editor for photo retouching and compositing.
GIMP (GNU Image Manipulation Program) is the most complete open-source counterpart to Photoshop for photo retouching, compositing, and image authoring, in development since the 1990s. The 3.x era has modernized it substantially: GIMP 3.0 (March 2025) introduced non-destructive editing for most commonly used filters, better PSD export, and editable text styling, and the project has kept a steady release pace since (3.2.4 as of April 2026). It runs entirely on your own machine with no account, and the honest trade-off is a learning curve: the interface and shortcuts differ from Photoshop's, and some professional features — full adjustment-layer parity, CMYK prepress — are still behind.
Affinity by Canva
The full pro suite — pixel, vector, and layout — now genuinely free.
Affinity was the classic one-time-purchase Photoshop rival; after Canva's acquisition it was relaunched in late 2025 as a single free desktop app combining what used to be Affinity Photo, Designer, and Publisher — full pixel, vector, and layout studios with no feature limits or subscription. It's closed-source and needs a Canva account to activate (it works offline afterwards), and Canva's AI extras are the paid upsell. For someone who wants professional-grade Photoshop power without a subscription and without open-source trade-offs, this is now the strongest commercial answer.
