How to convert MPEG to WEBM
- Add your .MPEG file - drop it in the box above or click to browse.
- Convert it to .WEBM in a few seconds.
- Download your new .WEBM file.
What to expect
- MPEG to WEBM is a full re-encode - every frame is decoded and re-compressed, so a small quality loss is unavoidable regardless of which tool you use.
- VP9 encoding is significantly slower than MPEG-2; expect a long wait for large files. Switching to VP8 speeds things up at the cost of slightly larger output.
- If broad device playback rather than web embedding is your goal,
.mp4(H.264) is usually a better and faster target than WEBM.
Frequently asked questions
Can I just rename .mpeg to .webm?
No - they use completely different codecs and containers. Renaming produces a file that will not play; you must re-encode.
VP8 or VP9 - which should I choose?
VP9 is recommended: it delivers smaller files at the same quality and is supported in all current browsers. Use VP8 only if you need faster encoding or compatibility with very old players.
Will the WEBM file be smaller than the MPEG?
Usually yes - VP9 is far more efficient than MPEG-2, so at a sensible quality setting the
.webm is often noticeably smaller.Why does the conversion take so long?
Every frame must be decoded from MPEG-2 and re-encoded into VP9, which is a computationally heavy codec - this is normal. Choose VP8 or a lower quality setting if you need faster output.
