It provides a comprehensive selection of photo editing tools in a tiny 7 MB download. It runs on any Windows machine (XP through Win 8.1) and does not require installation. It can easily be run from a portable USB drive or SD card. English, Dutch, French, German, and Italian translations are currently provided.

PhotoDemon is written in VB6. (Don't laugh until you've tried it - its performance will surprise you!) Outside contributions from both coders and translators are always welcome.

For information on the most recent official release, please visit: http://photodemon.org

Finally, note that PhotoDemon's GitHub repository does not contain a compiled EXE. If you don't have access to a VB6 compiler, you can download a compiled .exe (including language files and core plugins), updated nightly, from: http://photodemon.org/downloads/nightly/PhotoDemon_nightly.zip

PhotoDemon is designed to be run as a standalone program. No installer is provided or required. It does not touch the Windows registry, and aside from a temporary file folder – which you can specify in the Options dialog – it leaves no trace of itself on your hard drive. Many people choose to run PhotoDemon from a USB drive. It will run on any Windows machine from XP through Windows 8.1.

Complex editing actions can be automated by recording them as macros (similar to Office software). Once recorded, any combination of actions can be automatically applied to other images. Macros fully integrate with a built-in batch processing tool – simply choose a saved macro and a folder or list of images, and PhotoDemon will apply the macro to every image automagically.

Most free, open-source image editors are usability nightmares. PhotoDemon tries not to be. The interface was built by designers, not engineers, and small touches like save/load presets on all tools, automatic last-used settings preservation, unlimited Undo/Redo, "Fade last effect", keyboard accelerators, effect previews, mouse wheel and forward-back button support, and descriptive menu icons make PhotoDemon easy to use for both novices and professionals.

• Extensive file format support, including all major RAW formats (via LibRaw).
• Powerful selection tools, with full support for antialiasing, feathering, and on-canvas sizing/moving.
• Fully color-managed workflow, including support for embedded ICC profiles (even CMYK ones!).
• 2D transformations: advanced resize (Sinc, Catmull-Rom, etc), content-aware scaling, crop (including autocrop), rotate, shear, tiling.
• Pro adjustment tools: levels, curves, white balance, shadow/highlight correction, grayscale, sepia, full-featured histogram, green screen, Wratten filters, and many more.
• Filters and effects: content-aware blur, unsharp masking, edge detection, noise removal, lens diffraction, vignetting, perspective correction, film grain, and many more.
• 100+ tools are provided in the current build, plus a custom filter tool that allows you to construct your own convolution filters.

• PhotoDemon does not support layers, but layer support is actively being developed as of January 2014.
• PhotoDemon does not provide any on-canvas painting tools. Many have been prototyped, but their integration has been postponed pending a final layers implementation.
• PhotoDemon (probably) does not run on non-Windows operating systems. Wine (http://www.winehq.org/) finally added full DIB support in March 2012. Because PhotoDemon relies heavily on DIB sections, it may work on OSX, Linux, BSD, Solaris or Maemo systems with Wine v1.4 or later.

PhotoDemon is written and maintained by a single individual with a family to support. The program is provided free-of-charge under an extremely permissive open-source license, and no fees or money will ever be charged for its use.

That said, donations go a long way toward supporting the development of this powerful photo editing tool. If you would like to donate and support development, please visit:

While I can't make any promises, I have been known to give extra attention to feature requests from individuals who donate.

If you can't contribute monetarily to the project, here are other ways to help:

• Let me know if you find any bugs. Issues can be submitted via PhotoDemon's github page: https://github.com/tannerhelland/PhotoDemon, or this dedicated PhotoDemon feedback form: http://photodemon.org/about/contact/
• Are you a VB6 coder? I'm always open to outside bug fixes and feature implementations from fellow programmers.
• Tell friends, family, and other websites about PhotoDemon. If you know a site that tests or reviews image processing tools, email and ask if they've tried it.
• Send me an email and let me know how you use PhotoDemon. I love to hear from users. Get in touch at http://photodemon.org/about/contact/
