OGV to AVIF Converter

OGV to AVIF Frame Extractor

OGV is Xiph.Org's open Ogg video container — the royalty-free format of the pre-H.264 web era, whose video track is almost always Theora. AVIF is the AV1 Image File Format, a modern still picture built on the AV1 codec. This tool does not convert the whole clip: it pulls a single frame out of an OGV at the timestamp you pick and saves that one moment as an AVIF image. Both formats are open and royalty-free, so the still you rescue from an old Ogg archive stays inside the open ecosystem rather than moving to a patent-encumbered one.

How to Convert OGV to AVIF

1. Upload Your OGV File: Drag and drop your .ogv onto the page, or click "Add Files" to browse. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.
2. Pick the Frame with "Specific Frame": Choose Specific Frame and type the moment into Time (seconds) — decimals work, so 4.120 lands on the frame at 4.12 seconds. That single frame becomes your AVIF. To grab a batch instead, switch to Multiple Screenshots, which samples frames across the clip and returns them together as a ZIP.
3. Set Quality and Size (Optional): Leave Quality Preset on Very High (Recommended), or pick Specific file size to cap the output. Scale the frame down with Resolution Percentage, Preset Resolutions, or Width x Height.
4. Convert and Download: Click "Convert" and download your AVIF image. No sign-up, no watermark.

Frequently Asked Questions

Is the output a still AVIF or an animated one?

A single still image. AVIF can hold animation — it is built on the AV1 video codec — but this tool extracts one frame at the timestamp you enter under Specific Frame and encodes it as a static picture. If you want several stills from one clip, Multiple Screenshots saves a batch across the video as a ZIP. If you want the moving clip in a modern format rather than a frozen frame, keep it as video with Convert OGV to MP4.

Will AVIF make my old OGV frame look sharper?

No — and this is the honest catch. Theora-era OGV is almost always standard definition (480p or lower), and AVIF cannot reconstruct detail the original Theora encode never stored. AVIF is a more efficient codec, so it saves that same picture in a smaller file with cleaner gradients and fewer blocking artifacts than JPEG — but it gives you a modern, well-compressed copy of an SD-era still, not an upscaled or restored one. The pixels you start with are the ceiling.

Why are both OGV and AVIF described as "open"?

Because they come from the same lineage of royalty-free formats. Ogg and Theora are Xiph.Org projects, free of patent licensing, and AVIF is the Alliance for Open Media's still-image format built on the royalty-free AV1 codec. Converting an OGV frame to AVIF keeps the image inside the open ecosystem end to end — no licensed codec like HEIC's HEVC sits in the chain. If you would rather use a universally compatible format instead, Convert OGV to JPG covers everything that opens a picture.

My OGV won't play in Chrome anymore — can you still read it?

Yes, and it is a good reason to grab your frames now. Google removed Theora — the codec most OGV files use — from Chromium in Chrome 123 (announced October 2023, stable March 2024), and Firefox followed, so an .ogv may no longer play directly in a browser. That removal only affects in-browser playback; standalone decoders in VLC and FFmpeg still read the file, which is exactly how this tool decodes your source and captures the frame — it does not depend on any browser keeping Theora support.

Which version of AVIF does this output, and what can open it?

The output is a static AVIF still coded with AV1, built on the HEIF/ISOBMFF structure the format has used since the February 2019 specification. AVIF opens in roughly 93% of browsers in use today, per caniuse.com: Chrome 85+, Firefox 93+, Edge 121+, and Safari 16.4+ (macOS 13 / iOS 16, from 2023). Older browsers and some desktop image viewers won't open it — if you need a still that opens anywhere, including legacy apps and email, extract the frame as PNG for a lossless, near-universal result.

How much smaller is an AVIF still than the same frame as JPEG?

AVIF generally produces files noticeably smaller than JPEG at the same visual quality, with cleaner gradients and fewer blocking artifacts. In our testing, a 480p Theora frame saved at the Very High preset came out in the low tens of kilobytes — smaller than the equivalent high-quality JPEG of the same frame. The exact ratio depends on scene complexity: flat, smooth frames compress the most, while busy textured frames close the gap.

How are my files handled, and how long are they kept?

Your OGV is uploaded over an encrypted (TLS) connection, the frame is captured and encoded to AVIF on our servers, and the files are deleted automatically a few hours after conversion. There is no sign-up, no watermark on the output, and your files are never shared or made public. The frame is captured at the video's native resolution, and you can scale it down with Resolution Percentage or Width x Height before downloading.

Can I get a contact sheet of frames instead of one image?

Yes. Switch from Specific Frame to Multiple Screenshots, which samples frames at a set interval across the whole clip and returns them together as a ZIP of AVIF stills rather than a single timestamped picture. This is the quick way to find the best moment in a longer OGV without re-running the conversion for each guess — pick the interval, download the batch, and keep the frame you want.
