About this tool, tips & FAQ
What are custom FFmpeg commands for?
Custom FFmpeg commands allow you to tailor audio and video conversions, trim media, change codecs, and apply filters that suit your specific needs before executing the task in your browser.
Can I reorder multiple files before running a command?
Yes, the interface supports drag-and-drop reordering so you can control the processing sequence for multi-file batches before applying your custom command options.
Do my files leave the browser during processing?
No, everything runs locally in your browser; files never leave your machine and the FFmpeg runner only downloads the final output after your custom command completes.
