Is the MKV to GIF 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 MKV file never leaves the browser tab.

Will the GIF have sound?

No — GIF can't store audio, so the soundtrack is dropped and the result loops silently.

How do I convert MKV to GIF?

Drop your MKV file above (or click Browse) — the output is already preset to GIF — then click Convert and download the result.

Convert MKV to GIF

Convert MKV to GIF in seconds, free and entirely in your browser. MKV (Matroska) is a flexible container favoured for high-quality, multi-track video; GIF is a silent, looping animation that embeds almost anywhere. 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.
