WebM vs OGG: Format Comparison
Key differences between the two formats
| Feature | WebM | OGG |
|---|---|---|
| Type | Open web video container | Open audio container (Vorbis codec) |
| Contents | VP8/VP9 video + Vorbis/Opus audio | Vorbis audio only |
| Developer | Google / WebM Project | Xiph.Org Foundation |
| License | Open-source, royalty-free | Open-source, royalty-free |
| Browser support | Chrome, Firefox, Edge (video) | Chrome, Firefox, Edge (audio) |
| File size | Moderate to large (video included) | Small — Vorbis-compressed audio only |
| Use case | HTML5 web video | Web game audio, Linux audio, HTML5 audio tag |
| Metadata | WebM segment tags | Vorbis comments (artist, album, track, etc.) |
When to Convert
Common scenarios where this conversion is useful
Extract game audio for HTML5 web games
Web games commonly use OGG for audio assets because it is supported natively in Chrome, Firefox, and Edge without plugins. Extract soundtrack or sound effect audio from WebM game video files to OGG for use in your game engine.
Convert browser screen recordings to open audio format
Screen recordings made in browsers often produce WebM files. If you only need the audio — such as a voice-over or narration — extract it to OGG for a compact, open-format audio file.
Build an open-source audio library from web video
If you maintain a music or sound library using open-source tools on Linux, OGG is the native format for most Linux audio players. Convert WebM video audio to OGG to fit naturally into these workflows.
Prepare audio for Godot or other open-source game engines
Godot's audio system uses OGG Vorbis for streaming audio. If your audio assets exist as WebM video files, convert them to OGG to use directly in your Godot project without additional conversion steps.
Reduce file size for audio-only web content
Removing the video stream from a WebM file and keeping only the OGG audio significantly reduces file size, making it faster to load as background music or ambient sound on a web page.
How to Convert WebM to OGG
-
1
Upload your WebM file
Drag and drop your .webm file onto the converter or click to browse and select it. Files up to 500MB are supported.
-
2
Server-side OGG encoding
Your WebM is uploaded over HTTPS and FFmpeg extracts and decodes the audio stream (Vorbis or Opus), encoding it as OGG Vorbis. The video stream is discarded. Processing typically takes just seconds.
-
3
Download your OGG file
Click Download to save the .ogg file. The original WebM and converted OGG are automatically deleted from our servers after you download.
Frequently Asked Questions
Both WebM and OGG are open-source formats developed by the Xiph.Org and Google communities. WebM can actually contain Vorbis or Opus audio — the same codecs used in OGG files. Converting WebM to OGG extracts the audio-only stream into the OGG container.
If your WebM uses Vorbis audio, FFmpeg can potentially stream-copy the Vorbis data into an OGG container with no re-encoding and no quality loss. If the WebM uses Opus, re-encoding to Vorbis is required, introducing minimal quality loss.
Yes. OGG Vorbis is natively supported in Chrome, Firefox, and Edge via the HTML5 audio element. It is a widely accepted format for web audio without requiring any plugins.
OGG Vorbis is completely royalty-free with no patent restrictions, making it ideal for open-source projects and commercial web use. At equivalent bitrates, OGG Vorbis also delivers audio quality comparable to or better than MP3.
Godot uses OGG Vorbis as its primary audio streaming format. Unity, Unreal Engine, and GameMaker also support OGG. Converting WebM audio to OGG is a standard step in game audio pipelines for web or open-source games.
Yes. OGG Vorbis supports up to 255 audio channels. If your WebM contains surround audio, FFmpeg will preserve the channel layout in the OGG output.
Yes. ChangeThisFile is completely free with no signup and no limits on conversions. OGG is also a completely free format, so the entire workflow has zero cost.
Opus is a newer, more efficient codec that also uses the OGG container. OGG Vorbis is optimized for music at medium-to-high bitrates, while Opus is optimized for speech and low-bitrate streaming. For music content from WebM, OGG Vorbis is typically the better output choice.
FFmpeg uses a high quality Vorbis encoding setting by default, typically equivalent to 192 kbps. The exact bitrate varies with Vorbis VBR encoding based on audio content complexity.
Yes. All uploads use HTTPS encryption. Files are deleted from our servers immediately after conversion is complete. We never access or retain your files.
