Target-size mode
Enter the size you must hit and OneFreePlace allocates the available bitrate across video and audio after accounting for duration. This is useful for email, upload portals and storage limits where “CRF 28” alone is not predictable enough.
Quality mode
Use constant-quality compression when visual consistency matters more than a precise file size. Resolution, frame-rate and audio controls let you avoid wasting bitrate on pixels or frames your destination does not need.
Local-first video processing
The selected file is written into a browser-local FFmpeg/WebAssembly filesystem. It is not sent to a OneFreePlace server. Large 4K files can be memory intensive, so desktop browsers are recommended for heavy jobs.
