Are these video editing tools really free?
Yes. Every tool on this site is free, with no account, no trial limit, and no watermark on the output. The tools run on FFmpeg WebAssembly inside your browser, so there are no server costs to pass on to you.
Do my videos get uploaded to a server?
No. Processing happens locally in your browser — you can open DevTools → Network while a tool runs and verify that nothing is uploaded. That also makes local processing faster than upload-based editors for large files.
Is there a file size limit?
There is no hard limit and no paywall for big files. Practical capacity depends on your device memory; 2 GB videos process fine on a typical laptop.
Which formats are supported?
Video: MP4, MOV, WebM, MKV, AVI and more. Audio: MP3, WAV, AAC, M4A, FLAC, OGG. Images: PNG, JPG, WebP, HEIC, AVIF, GIF. See the converter pages for the full matrix.
