Spec score 8.5 #3 of 33 in GIF Maker Software

What it is

Gifsicle is a free command-line tool for creating, editing, and inspecting GIF images and animations. It can combine GIF inputs into animations, set frame delays and looping, and extract, insert, replace, or delete frames. Image options include resizing, cropping, flipping, rotating, changing transparency, and reducing colors. Its animation optimizer offers three levels and stores changed portions of frames, though optimization can sometimes increase file size. Gifsicle can print detailed GIF information, including comments, and control interlacing, palettes, and transparency. Batch mode changes GIF files in place. The distribution also includes gifview, an animated-GIF viewer, and gifdiff, which compares GIFs for identical visual appearance. It is available for Linux, macOS, and Windows, with a source archive provided by the maker. Building it requires an ANSI C compiler. The manual notes that some Java and Internet Explorer versions may not display minimal optimized GIFs correctly; the careful option writes slightly larger files to avoid those compatibility problems.
