Gifsicle vs LICEcap

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.

LICEcap captures a selected area of a Windows or macOS desktop and saves animated recordings as GIF or LCF files. During recording, the frame can be moved, recording can be paused and restarted, and an optional text message can be inserted when pausing. Shift+Space provides a global pause toggle. Capture settings include a maximum frame rate, a basic title frame, mouse-button recording and elapsed-time display. LCF is the native format; the maker says it offers higher compression than GIF, more than 256 colors per frame and more accurate timestamps. LCF recordings can play in REAPER, where they can be converted to GIF or another video format. LICEcap is GPL free software, and download packages include source code. Version 1.32 downloads for Windows and macOS are dated June 8, 2022. Listed Windows support spans XP through 11, while macOS requirements cover 10.7–12.x on Intel 64-bit or M1. The maker recommends a reasonably fast CPU and at least 1GB of RAM, especially for LCF encoding. Discussion is directed to Cockos Forums.
