About

Video processing, done in your browser.

Our mission

Fast, free, browser-based video encoding and compression.

TranscodeX is a browser-based video encoder and compressor. Instead of sending your video to a server, it runs FFmpeg compiled to WebAssembly directly in your browser. Your device does the processing, and the optimized video is downloaded right back to you.

Why the browser does the work

Traditional converters upload your file, queue it on a server, process it, and hand the result back. TranscodeX removes that round trip entirely.

No upload step

Your video is read locally and encoded locally. There is no source-file upload during the normal workflow.

No queues, no waiting

There is no server queue to sit in. Processing starts the moment you click, on your own hardware.

Free to use

TranscodeX is free. Because processing runs on your device, there are no usage limits tied to a server.

WebAssembly power

FFmpeg compiled to WebAssembly runs near-native code in a secure browser sandbox.

One-click presets tuned for Reels, Shorts, TikTok and other platforms.

No account required

Who it is for

Teams & marketers

Students & educators

Shrink lectures and demos for email and course platforms, even on modest hardware.

Straight talk about limits: Browser encoding uses your device’s CPU and memory. Very large or high-resolution videos take longer than they would on a server, and extremely large files can exceed what a browser can handle. We say so rather than pretend otherwise.
