What to expect
Processes locally with FFmpeg. Browser processing uses WebAssembly and downloads the engine on first use; large videos are better suited to the CLI. Re-encoding may lose quality. GIF output has no audio. Browser limits: 1080p, 5 minutes, 32 MiB input and output.
Do my files leave my device?
No. Thanks to advanced file-processing technology, your files are processed directly on your device, inside your browser. OneKit does not receive your input files or results. Required public processing libraries may download when you first use the tool.
