Is the GIF to WEBM converter free?

Yes. Transcodr is free with no accounts, watermarks, or hard limits beyond your device's available memory.

Are my files uploaded to a server?

No. The conversion runs locally via ffmpeg compiled to WebAssembly, so your GIF file never leaves the browser tab.

Will the video lose quality?

Re-encoding always involves some loss, but you can raise the quality control before converting. WEBM uses vp9 (Profile 0).

Convert GIF to WEBM

Convert GIF to WEBM in seconds, free and entirely in your browser. GIF is a silent, looping animation that embeds almost anywhere; WebM is Google's royalty-free format built for fast-loading web video. Transcodr runs real ffmpeg compiled to WebAssembly, so your file is processed on your own device and never uploaded.

Drop files to convert

Video, audio, images, subtitles: anything ffmpeg can read. Drop them anywhere on the page or browse from disk.

01 / Engine

Real ffmpeg, compiled to WebAssembly.

Same library Netflix, YouTube, and basically every command-line video tool relies on, running in a Web Worker. Pipe a file in, run a command, pipe bytes back out.

02 / Privacy

Nothing leaves the tab.

No uploads, no accounts, no telemetry beyond an anonymous pageview. We couldn’t see your files if we wanted to — there’s no server in the loop.

03 / Limits

It is, after all, a tab.

Files up to a few hundred megabytes convert comfortably. Beyond that, your browser starts asking pointed questions. Use the desktop ffmpeg for 4K masters.
