What it does
PhotoDemon is a portable Windows photo editor with layers, content-aware fill, lens correction and a built-in batch processor.
PhotoDemon runs on Windows without installation or administrator rights; the project also says internet access is unnecessary. Layers and presets support an edit, while macros and batch processing repeat adjustments. Developer notes introduced the layered PDI format in 6.4 and documented separate file exports in 2024.7. Exporting a flat or lossy copy does not update the working document's save state, so save the editable document separately. Save/Save As filename incrementing is configurable. Check those preferences when repeating exports.
