How it worksShow guide
Introduction
Drop a video, pick an output format, and re-encode locally with FFmpeg.wasm. Choose quality, resolution, frame rate, codecs, trim points, rotation, and speed. Audio-only exports extract a soundtrack without uploading anything.
Step-by-step
- Drop a video or audio file (up to 100 MB)
- Choose format, quality, and optional advanced settings
- Convert, then download the result
Worked example
The converter scales to 720p, encodes H.264 + AAC with a balanced CRF, and writes a fast-start MP4 for web playback — all in this tab.
Use cases
- Compress a phone video before sharing
- Convert MOV/WebM to MP4 for wider compatibility
- Make a short GIF from a clip
- Extract MP3 or AAC audio from a recording
Frequently asked questions
Does my video leave the browser?
No. Conversion runs with FFmpeg.wasm in this tab. The engine may download once from a CDN on first use; your media file is not uploaded to Bestrao.
How large a file can I convert?
Up to 100 MB. Larger clips may exhaust browser memory — trim first or lower resolution if conversion fails.
Which formats are supported?
Outputs include MP4 (H.264), WebM (VP9), animated GIF, and audio-only MP3, AAC, or WAV. Inputs cover common containers such as MP4, MOV, WebM, and MKV, depending on the FFmpeg build.
