# Compress, Retime and Edit GIFs in Your Browser (No Upload)

Short looping GIFs are great for tutorials, bug reports and social posts, but the raw files are usually too heavy to share. A browser-only workflow solves that without installing anything or sending your files to a server.

What the free tools cover:
- Compress GIF files up to 100 MB while keeping the loop intact.
- Change playback speed by rewriting frame delays instead of re-encoding the whole file.
- Remove, reorder or retime individual frames when a loop is too long or a frame is wrong.

Because processing happens locally in the browser, the file never leaves your machine — useful when the GIF contains unreleased UI, client work or personal footage.

Note: the prompt-based and photo-based generator is currently offline; the compression, speed and frame editing tools are free and work in the browser.
