In their own words
Curtail
Curtail is a free Linux application for compressing PNG, JPEG, WebP, and SVG images. It offers both compression modes and lets users decide whether image metadata is retained. Recursive directory compression supports batch processing across folder contents. When compression would produce a larger file, Curtail restores the original. Actions are provided to open a compressed image and reveal it in its folder. The project is released under the GNU General Public License version 3 or later and uses open-source components including Oxipng, pngquant, Jpegoptim, libwebp, and Scour. The project recommends installing its Flatpak package from Flathub; unofficial Snap, Ubuntu PPA, and Fedora COPR packages are also listed. Flathub marks the app as potentially unsafe and lists read/write access to the home folder. The GNOME page lists version 1.17.0, released on 2026-10-05, and links to an issue tracker. Curtail is available at no cost, with no trial required.
