How to convert OGV to WEBM
- Add your .OGV 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
- Re-encoding from OGV to WEBM is lossy - every conversion reduces quality slightly; keep the original
.ogvif you may need to convert again later. - VP9 compresses noticeably better than Theora, so the output
.webmcan actually be smaller than the original OGV at similar visual quality. - OGV files usually carry Vorbis audio; converting to WEBM switches the audio track to Opus, which offers better quality at lower bitrates.
Frequently asked questions
Will I lose quality converting OGV to WEBM?
Yes - both formats use lossy compression, so re-encoding always reduces quality slightly. Use a high-quality FFmpeg setting such as
-crf 30 -b:v 0 to minimise the loss.Does WEBM play in all browsers?
Chrome, Firefox, and Edge support WEBM/VP9 natively. Safari added VP9 support in version 14 (macOS Big Sur / iOS 14), so compatibility is now broad.
Should I use VP8 or VP9 for the output?
VP9 produces smaller files at the same quality and is supported by all modern browsers; use VP8 only if you need compatibility with older devices or encoders.
Is there any reason to keep the original OGV file?
Yes - the original holds the source quality. Re-encoding from an already-converted WEBM would reduce quality a second time.
