FFmpeg in the Browser

Transcode, remux, trim, probe and extract — powered by FFmpeg compiled to WebAssembly. Your media never leaves this browser tab.

FFmpeg core
Single-threaded core from unpkg (@ffmpeg/core 0.12.6). Loaded once per session, on demand.
Input media
Drag a file here or browse. Audio, video and images are all supported.
Command
Pick a preset or edit the arguments directly. Use {input} and {output} placeholders — they are substituted with the working filenames at run time.

Print stream, codec, duration and metadata to the log. No output file is produced.

Log console
Live output from ffmpeg. Stream info from a probe shows up here.

No output yet. Load the core and run a command.
