About us
Every GIF tool. Zero uploads.
ZipGIF is a set of free GIF tools that run completely inside your web browser. When you add a GIF, nothing is uploaded: the file is read from your device into browser memory, processed there, and handed straight back to you as a download.
The engine is Gifsicle, a long established open source GIF optimiser, compiled to WebAssembly and run inside a background Web Worker so the interface stays responsive. There is no upload endpoint, no queue, and no storage bucket, because the only CPU involved is your own.
GIF tools, all client side
Files ever uploaded
Processing done in your tab
Why we built it
Most online GIF tools ask you to hand your file to a stranger's server, wait in a queue, and trust a privacy policy you did not read. That felt backwards for something a browser can already do. So ZipGIF does the work locally, at native speed, and keeps your files on your device.
Honest limitations
Browser based processing has real limits and we would rather state them. Very large files can exhaust the memory a tab is allowed to use, long GIFs take longer to analyse, and compression is lossy above a certain point. No tool can shrink a detailed 30 second GIF to 256 KB without visible quality loss.

Working on ZipGIF
Every tool ships with the same rule: if a feature needs a server, it does not get built. That constraint shapes the roadmap. Compression, cropping, resizing, speed changes, splitting, trimming and PNG conversion all run through the same local engine, so anything new has to fit inside a browser tab too.
If your work depends on a GIF step that is still slow today, say which one. Real workflows decide what gets built next.
