PhotoDemon

PhotoDemon is a free, open-source photo editor for Windows with an unusual selling point: you do not install it. Extract the download into a folder or onto a USB stick and run the program from there. It needs neither administrator rights nor an internet connection to edit your pictures. The stable download is about 22 MB, which makes it worth considering when a large creative suite would be excessive.

Portability does not mean this is a glorified crop button. PhotoDemon has layers, selection tools, brushes, content-aware fill and resize, lens and perspective correction, plus shadow and highlight adjustments. Its official format support includes Photoshop PSD, GIMP XCF and PaintShop Pro PSP files. That is useful for exchanging images, although opening another editor's project should not be taken as a promise that every application-specific effect will survive unchanged. Keep the original project and check the result before overwriting anything.

The other reason to shortlist it is repetitive work. Its macro recorder and batch processor let you apply a recorded sequence to more than one image, while live previews and saved presets help keep adjustments consistent. My pick for PhotoDemon is a portable editing kit, not a replacement for every photographic workflow: use it when you want local editing and layers without setting up a larger application. It is Windows-only, so users who switch between operating systems should consider a cross-platform editor instead. Tanner Helland develops the project under a BSD license, with no paid edition required for the tools described here.
