OGV to AVI Converter
FileFlip converts OGV to AVI entirely inside your browser, using FFmpeg compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert an OGV file to AVI?#
- Drop your OGV file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to AVI and the conversion starts on its own. FileFlip downloads 30.8 MB of WebAssembly the first time and nothing after that, then runs FFmpeg on your own machine.
- Save the AVI file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting OGV to AVI lose quality?#
It depends on what is inside the file. OGV is a container rather than a codec, so whether the AVI conversion copies the streams across untouched or re-encodes them is decided by the codecs that particular file happens to use.
Is it safe to convert OGV files online?#
Yes, because nothing is uploaded. FileFlip converts OGV files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What OGV to AVI actually does to the file#
Converting OGV to AVI runs on FFmpeg, downloads 30.8 MB of WebAssembly the first time and nothing after that, re-encodes or copies through depending on the codecs in the file, and drops encoded streams.
| Engine | FFmpeg |
|---|---|
| Conversion path | One step: OGV → AVI |
| Downloaded to your browser | 30.8 MB, once, then cached by your browser |
| Quality | Decided by the codecs inside the file |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| Encoded streams | Dropped | The target format has nowhere to put it. |
What is an OGV file?#
An OGV file holds video wrapped in Xiph.Org's Ogg container, almost always Theora-encoded video paired with Vorbis audio, built as a patent-free alternative at a time when H.264 carried real licensing costs.
Reach for OGV only when a target system specifically requires Ogg Theora, such as older Wikimedia tooling or a free-software media pipeline that has not moved on.
Convert OGV to MP4 or WebM for anything that needs to play in a current browser, since native Theora support has been dropped from both Chrome and Firefox.
What is an AVI file?#
An AVI file interleaves video and audio in chunks of Microsoft's RIFF structure, the container Windows has used for video since 1992 and the one most video from the DivX and Xvid years is stored in.
Keep a file as AVI when it is going into software old enough to predate MP4, which is the one situation where the format's age helps.
Convert AVI to MP4 to get the video playing on phones, browsers and TVs, and to shrink it, since what is inside an AVI is usually a codec generation or two behind.
OGV to AVI questions people ask#
What plays OGV files today?
VLC opens OGV files on Windows, macOS and Linux without any extra codecs, since it bundles its own Theora and Vorbis decoders. mpv and GNOME Videos on Linux handle it the same way. Neither Chrome nor current Firefox will play an OGV file dropped straight into the browser any more.
Does Wikipedia still use OGV?
Wikimedia sites used OGV as their standard video format for years because Theora and Vorbis carry no patent licensing, matching the free-content mission of the projects. Wikimedia has since moved to VP9 for new video, though a large amount of older OGV footage remains on Wikimedia Commons.
Is Ogg the same thing as OGV?
Ogg is the container format, and OGV is the specific case of an Ogg file holding a Theora video stream, the same way MP4 is a container and M4V is one particular use of it. A plain .ogg extension more often holds Vorbis audio with no video track at all.
Why won't my AVI file play?
An AVI that will not play is usually encoded with a codec the machine does not have. AVI identifies its video by a four character code and leaves the decoder to the operating system, which is why Windows users spent years installing codec packs. Old DivX, Xvid, Indeo and Cinepak files all hit this. VLC ships its own decoders and plays most of them, and converting to MP4 removes the problem permanently.
