Turn your OGV file into an MP4 that plays where you need it, right in your browser.
Drag and drop the file, or click to browse. Files up to 500 MB are supported, and nothing is installed.
MP4 is already selected, so there is nothing to configure. You can switch formats in the panel if you need to.
We convert on our servers, usually in under a minute. Create a free account to download the MP4, or keep editing the file in REQO.
OGV is Ogg video, almost always Theora and Vorbis. It was the patent-free answer to H.264 in the early HTML5 years, and it has been comprehensively overtaken: WebM and MP4 both look better at a smaller size.
The practical problem: Safari, iOS and most devices will not play Theora. Editors and upload forms reject the extension. Theora compresses noticeably worse than H.264 or VP9.
MP4 solves that. Plays natively on every phone, browser, TV and editing app with no extra codecs. Every upload form accepts it, from YouTube and LinkedIn to Slack and email. H.264 keeps files small enough to send while still looking sharp at 1080p.
OGV was the patent-free HTML5 video format before WebM took over, and it has aged badly: Safari and iOS never supported Theora, and the compression is well behind H.264. If an OGV is the only copy of something you care about, MP4 is the format to keep it in.
| OGV | MP4 | |
|---|---|---|
| Container | Ogg | MPEG-4 Part 14 |
| Typical codecs | Theora video, Vorbis audio | H.264 video, AAC audio |
| Best for | Open-source projects and older HTML5 video | Sharing anywhere, uploads, web embeds |
| Plays on | Firefox and Chrome; poor elsewhere | Every phone, browser, TV and editor |
| File size | Large for the quality | Small for the quality |
Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the MP4 itself beyond the free-plan badge.
No. The conversion runs on our servers and the whole flow happens in your browser, so it works the same on Windows, macOS, Linux, iPhone and Android.
Converting re-encodes the video, so it is not bit-for-bit identical. We encode at a high quality target, which keeps the result visually indistinguishable from the OGV on normal viewing. Converting the same file back and forth repeatedly will eventually show, so keep your original.
Up to 500 MB per file. For anything bigger, trim or compress it first, both are free tools here.
Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
