PhotoDemon is a portable photo editor. It is 100% free and 100% open-source.

The app provides a comprehensive selection of photo editing tools in a very small download. It runs on any Windows machine (XP through Windows 11), and as a portable app, you can carry it around on a USB drive or SD card. It never needs to be installed, and it does not require administrator access to run.

PhotoDemon is designed to work anywhere in the world under any language and locale settings. Volunteer translations are currently provided for more than a dozen languages.

The program is available under a permissive BSD license. Outside contributions from coders, designers, translators, and enthusiasts are always welcome.

Ongoing development is supported by donations. If you enjoy the program, please consider a one-time donation or joining our Patreon campaign.

For anything else, you can reach me (PhotoDemon’s author) at tanner<at>photodemon.org. Because this is a volunteer effort, I can’t always promise a reply, but your email will always be read (…eventually).

Thank you for reaching out, and I hope you enjoy PhotoDemon.
