Skanlite is a free Linux application for scanning images with flatbed scanners. Supported scanners can capture photos, documents, transparent slides, and filmstrips. A preview and selection tool lets users define the final scan, and multiple selections can be taken from one image. Network scanners and batch scanning are supported. For saving, users may open a dialog for each image or save directly to a chosen folder with autogenerated names and format. Listed export formats are PNG, JPEG, JPG, JPEG 2000, and BMP. Linux installation is offered through Discover and other AppStream application stores, distribution package managers, and Flathub. The official page links to a handbook, forum, and bug-reporting route. Skanlite is published by KDE and listed under the GPL-2.0+ license. KDE says its software generally does not transfer device information except through explicit user action, while third-party distributors may modify software in privacy-affecting ways. The listed plan is free for desktop, with an 8 MiB download.
