## Overview
PhotoDemon provides a comprehensive photo editor in an 20 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](#licensing). Contributors have translated the program into more than a dozen languages.
You can support PhotoDemon's ongoing development [through Patreon](https://www.patreon.com/photodemon) or [with a one-time donation](https://photodemon.org/donate/).
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, customizable hotkeys, mouse wheel and X-button support, and descriptive icons make it fast and easy to use.
### Pro-grade features and tools
* Extensive file format support, including Adobe Photoshop (PSD), Corel PaintShop Pro (PSP), GIMP (XCF), and major camera RAW formats
* Advanced multi-layer support, including editable text layers and non-destructive layer modifications
* Color-managed workflow, including support for embedded ICC profiles
* On-canvas tools: digital paintbrushes, clone and pattern brushes, advanced selection tools, interactive gradients, and more
* Adjustment tools: levels, curves, HDR, shadow/highlight recovery, white balance, and many more
* Filters and effects: perspective correction, edge enhancement, noise removal, content-aware fill and resize, unsharp masking, gradient and palette mapping, and many more
* More than 200 tools are provided in the current build.
### Limitations
* PhotoDemon isn't designed for operating systems other than Microsoft Windows. A compatibility layer like [Wine](http://www.winehq.org/) may allow it to work on macOS, Linux, or BSD systems, but these configurations are not officially supported.
* Due to its portable nature, PhotoDemon is only available as a 32-bit application. (This means it cannot load or save images larger than ~2 GB in size.)
