About this site

FFmpeg Cookbook has browser tools for compressing and converting video, and guides to using FFmpeg. It is run by one person, FFmpeg Chef. There are 121 articles in English (125 in Japanese) and 43 tools.

Commands in the articles

Every command in the articles is run with FFmpeg to check it (1,557 commands as of 2026-09-26). Sizes and times were measured on this machine:

• Windows / Intel Core i9-14900KF / NVIDIA GeForce RTX 4090
• FFmpeg 8.1 (desktop build)

AI helps with drafts and translation; everything is checked, commands included, before it goes up.
