Overview

Screenshot

PhotoDemon provides a comprehensive photo editor in a 15 MB download. It runs on any Windows PC (XP through Win 11) and it does not require installation. You can run it from a USB stick, SD card, or portable drive.

PhotoDemon is open-source and available under a permissive BSD license. Contributors have translated the program into more than a dozen languages.

You can support PhotoDemon's ongoing development through Patreon or with a one-time donation.

New contributions from translators, coders, designers, and enthusiasts are always welcome.

What makes PhotoDemon unique?

Lightweight and completely portable

No installer is provided or required. Aside from a temporary folder – which you can specify in the Tools > Options menu – PhotoDemon leaves no trace on your hard drive. Many users run PhotoDemon from a USB stick or microSD card.

Integrated macro recording and batch processing

Complex editing actions can be recorded as macros (similar to Office software). A built-in batch processor lets you apply macros to entire folders of images.

Usability is paramount

Many open-source photo editors are usability nightmares. PhotoDemon tries not to be. Small touches like real-time effect previews, save/load presets on all tools, unlimited Undo/Redo, "Fade last action", keyboard accelerators, mouse wheel and X-button support, and descriptive icons make it fast and easy to use.
