Convert video formats with re-encoding
Each video converter preset pairs an output container with audio and video encoders. Video conversion changes the encoding instead of just renaming the file.

Common questions
Video Converter FAQ
Learn about supported formats, settings and how to convert video on your device.
Which formats does this video converter support?
Video converter presets cover MP4, MOV, MKV, WebM, AVI, FLV, MPEG, TS, M4V, OGV and 3GP. After you choose a video, only presets with available encoders and output containers are offered.
Can I convert video without uploading it?
Yes. Convert video locally in your browser, preview the result when your browser supports its format, and download the converted video. The video converter does not upload your selected file.
Can every input video be converted?
A file extension alone does not guarantee compatibility. The converter must be able to read the container and decode the video and any retained audio. Corrupt, encrypted or unsupported files may fail. You can try removing audio if only its codec is unsupported.
Why does my downloaded video not play in the preview?
The browser may not support playback of an output container or codec even when conversion succeeds. Download the file and open it in a compatible media player.
What happens to extra tracks and metadata?
The tool converts the first non-cover-art video track and optionally the first audio track. Extra audio tracks, subtitles, attachments and original metadata are not retained. MPEG output is set to 25 fps; 3GP is limited to 480p.
Do I need an account, and are my files uploaded?
No account is needed. The selected file is processed locally in your browser and is not uploaded to a server. Your original remains unchanged. Download the result before refreshing or leaving the page.
What are the file limits?
One video at a time, up to 200 MB. Processing needs an up-to-date browser with WebAssembly and Web Workers. Memory and processing time vary by device, and even files below this limit can be too demanding on a phone.
