How to use Video Format

1. Upload your video. Drag in any MP4, MOV, WebM, MKV, AVI, M4V, FLV, or WMV file — up to 500 MB.
2. Pick a target format. Choose MP4, WebM, MKV, or MOV from the dropdown.
3. Convert. We try a lossless stream copy first for speed. If the codecs aren't compatible, we re-encode.
4. Download. Preview the result and download your converted video.

Will the video be re-encoded?

We try a fast stream copy first (no quality loss). If the source codecs aren't compatible with the target container, we re-encode with H.264/AAC.

What's the best format for sharing?

MP4 (H.264) plays everywhere — browsers, phones, TVs. WebM is slightly smaller but less compatible. MKV is great for archiving with subtitles.

Does converting change quality?

Stream copy preserves 100% quality. Re-encoding is done at high quality (CRF 18) so differences are imperceptible.

Can I convert FLV or WMV?

Yes — upload any FLV or WMV file and convert to MP4. These legacy formats require re-encoding.

Where is my file processed?
