Perfect Viewer vs Pineapple Pictures

Perfect Viewer has no write-up on Specifiction yet; its figures are above.

Pineapple Pictures is an image viewer for opening common image formats on Linux, macOS, and Windows. Its listed formats include JPEG, PNG, GIF, SVG, PSD, KRA, XCF, TGA, HDR, and AVIF. A Stay-on-Top setting can keep a reference image visible above other software while you work. The project also lists RAW support and a metadata viewer; optional libexiv2 support is recommended for showing more image metadata.

The viewer is free, and Pineapple Pictures as a whole is licensed under MIT, though individual files may have other compatible licenses. Downloads are linked through GitHub Releases, SourceForge, Arch Linux AUR, itch.io, and FlatHub. Format availability depends on Qt imageformats plugins, which users may need to obtain from their distribution or build themselves on Windows. Release 1.6.0 lists Linux with Qt 6.4 or later and a stacking window manager, Windows x64, and macOS ARM. The maintainer says the project will remain in maintenance mode for the foreseeable future while continuing to receive updates. An itch.io purchase supports development and provides experimental additional format support.
