Compress GIFs Locally — Your File Never Leaves the Browser

What “online GIF compressor” usually means

A typical web compressor uploads your GIF to a remote server, runs FFmpeg or gifsicle there, then lets you download the result. That works, but it also means:

• The file leaves your device.
• Large GIFs hit upload limits or sit in a queue.
• You depend on someone else’s disk and logs.

How local compression works here

10mbgif.com runs the encoder in your browser with WebAssembly. The GIF is read, compressed, and saved on your machine. We never receive the file, so there is no server-side size cap and no “please wait in queue” for the actual compression.

That is also why a 50MB or 100MB source GIF is fine: you are using your own CPU, not an upload form with a 25MB ceiling.

When to use which tool page

• Discord chat GIFs — target 20MB (or 10MB / 8MB).
• Emoji & stickers — 256KB / 512KB.
• Hard 10MB cap — email, forums, older bots.
• Hard 20MB cap — Discord’s current upload limit.
