Supports: HEVC
This walks you through turning an HEVC (H.265) clip into an OGV file — the Ogg container's open, royalty-free video format — and, just as importantly, when you should not. HEVC is a modern, efficient, patent-encumbered codec from 2013; OGV almost always carries Theora, an open codec from 2004 that is less efficient and now being dropped by browsers. Read the trade-off below before you convert, because for most uses WebM or MP4 is the better target.
.hevc file onto the page or click "+ Add Files". You can queue several clips to convert with the same settings..ogv that old Ogg players expect, or switch to VP8 for noticeably better compression inside the same Ogg container. Leave Audio Codec on Vorbis, or pick Opus, FLAC, or Speex.The honest part first: this is a modern-to-older-open conversion. HEVC (2013) is one of the most efficient codecs in wide use; Theora (2004) sits roughly at H.264-baseline efficiency, well below HEVC. Because both are lossy, re-encoding HEVC into Theora is lossy-to-lossy — you cannot regain detail, and at the same visual quality the OGV will usually be larger than the HEVC source. What you gain is openness: Ogg/Theora/Vorbis is royalty-free, with no patent pool to license.
So the codec choice in step 2 matters:
.ogv most legacy software and Wikimedia-era tools expect.OGV/Theora is largely obsolete in 2026: browsers have moved to VP9 (in WebM) and AV1, which compress far better than Theora and still play natively. Convert to OGV only when a specific legacy target requires it — an old open-source player, an embedded device, or a Wikimedia-era pipeline that expects Ogg Theora. If you actually want a modern royalty-free format, HEVC to WebM (VP9 + Opus) is a much better choice; for universal playback on phones, TVs, and editors, use HEVC to MP4. DRM-protected or corrupted HEVC files cannot be re-encoded by any web tool.
Often, yes. HEVC (H.265, standardized in 2013) is far more efficient than Theora, the codec OGV usually carries (released in 2004). To hold the same visual quality, Theora needs more bits, so a same-quality OGV typically ends up bigger than the HEVC source. Switching the video codec to VP8 or setting a Specific file size under File Compression keeps it in check, but there is no way to beat HEVC's compression while staying in an Ogg/Theora file.
By default it produces Theora video with Vorbis audio — the classic .ogv most software means when it asks for the format. The Ogg container also supports VP8 video and Opus, FLAC, or Speex audio, all selectable under the codec options. Pick Theora + Vorbis for the widest compatibility with old Ogg players; pick VP8 for better compression in the same container.
For almost any modern use, WebM is the better target. Theora has been deprioritized — Chrome and Edge disabled it by default (around Chrome 123 in early 2024) and Firefox disabled it by default in version 126 — while WebM/VP9 plays in Chrome, Firefox, Edge, and Safari 16+. Convert to OGV only when a legacy tool specifically needs Ogg Theora; otherwise use HEVC to WebM for the open web or HEVC to MP4 for universal playback.
Yes, some — this is a lossy-to-lossy re-encode, and Theora is less efficient than HEVC, so at a matched file size the OGV looks a little softer than the source. The tool cannot improve on the original. To minimize loss, choose VP8 instead of Theora, raise the Quality Preset, or allow a generous Specific file size. The conversion can never make the OGV mathematically identical to the HEVC original.
The real reason is licensing and legacy compatibility. Ogg/Theora/Vorbis is completely royalty-free, with no patent pool — unlike HEVC, which is patent-encumbered. That matters for old open-source pipelines, MediaWiki/Wikimedia-era workflows that prefer patent-free formats, and embedded or Linux players built around Ogg. In our testing, an HEVC clip re-encoded with Theora + Vorbis at the default quality preset produced a standard .ogv that played in VLC and Firefox without any extra muxing step. For general playback, WebM or MP4 is still the better choice.
Your file is uploaded over an encrypted connection, converted on our servers, and the result is yours to download — no sign-up, no watermark, never shared or made public. Files are deleted automatically a few hours after conversion. If you need to go the other direction later, OGV to HEVC reverses the process, and Compress OGV shrinks an existing Ogg video.
