What is FFmpeg Generator?
FFmpeg can do almost anything with audio and video, but its syntax is famously dense. This free generator produces battle-tested commands for the most common tasks: format conversion, CRF-based compression, trimming by timestamps, resizing, extracting audio, high-quality GIF creation with palettegen, removing audio, concatenating clips, grabbing thumbnails and changing playback speed with matching audio tempo. Each command includes the right codec flags so you don't have to look them up.

Frequently asked questions
Is this FFmpeg command generator free to use?
Yes — this FFmpeg command generator is completely free with no signup, no limits, and no watermarks. Use it as often as you like.
What CRF value should I use for compression?
For H.264, CRF 18–23 is visually near-lossless, 23–28 is a good balance of size and quality, and above 28 artifacts become visible. Lower means better quality and bigger files; 23 is the default sweet spot for most videos.
Is my data private?
Completely. Everything you type stays in your browser — nothing is uploaded to any server, so commands, keys and data never leave your machine.
Do these tools touch my servers?
No. OpsForge tools are pure calculators and generators that run in your browser — they never connect to your infrastructure. You copy the result and apply it yourself.
Is the chmod calculator accurate for all systems?
Yes — octal permission notation is a POSIX standard, so the results apply identically on Linux, macOS and BSD.
Will more DevOps tools be added?
Yes — Dockerfile, docker-compose, nginx and CI config generators are on the roadmap. Everything will stay free and client-side.
