Will the video be kept in the OGG file?

No. OGG is an audio-only format. This conversion drops the video entirely and saves just the main audio track as Ogg Vorbis. If you need to keep the video, choose another tool or keep the MP4.

What quality is the OGG audio?

The preset uses Ogg Vorbis at quality 5, which is about 160 kbps variable bitrate. This is good enough for most music and all voice recordings. If you need higher quality, you’ll need a desktop tool with more settings.

How much smaller will my file get?

A 4-minute HD MP4 (about 50 MB) shrinks to 4–5 MB as OGG audio. The reduction is mostly from dropping the video. The actual size depends on the audio content—complex music is a bit larger, simple speech a bit smaller.

Does OGG play on iPhone or iPad?

OGG support on iOS is limited. Safari and the built-in Music app do not play OGG files. VLC for iOS and some third-party apps can play them, but for best compatibility, use MP3 or M4A if you’re targeting Apple devices.

Can I convert MP4 to OGG with built-in tools?

Windows and macOS don’t natively export OGG. VLC can do it (Media > Convert/Save), and Audacity can import MP4 and export OGG (with the right plug-ins). QuickTime and Windows Photos can’t export OGG. Videozify runs in your browser without needing installs.

Is this conversion lossless?

No. OGG Vorbis is a lossy format, similar to MP3. The audio is recompressed from whatever is in your MP4 (usually AAC) to OGG. There’s always a small quality drop, but at quality 5 it’s hard to hear for most uses.

What if my MP4 has no audio?

You’ll get an error or a silent OGG file. This tool only works if your MP4 contains an audio track. If you need to check or fix your audio, try previewing the MP4 in a player before converting.

Are there limits on file size or length?

Videozify runs in your browser, so the main limit is your device’s memory. Files up to a few hundred MB (about 1–2 hours of video) usually work on a desktop. On mobile, shorter clips are safer—very large files can cause the tab to reload.

An MP4 to OGG converter extracts the audio track from any MP4 video and saves it as an OGG (Ogg Vorbis) file. Videozify runs this entirely in your browser: your video never leaves your device. The audio is encoded to Ogg Vorbis at quality 5 (around 160 kbps variable bitrate), and the video is discarded. This makes OGG files that are compact, open, and ideal for music or voice, but not for retaining video.

How to convert MP4 to OGG

Drop your MP4 file onto the box above, or browse to select it from your device.
Wait for the file to load and check that it’s the right video.
Press Convert. The tool will extract and encode the audio as OGG.
Download your OGG audio file when it’s ready—no data is uploaded.

Why convert MP4 to OGG?

MP4 is a universal video format that can hold both video and audio in a single file. If you only need the audio—maybe for a podcast, background music, or voice sample—extracting it as OGG makes sense. OGG (specifically Ogg Vorbis) is an open, patent-free audio format that works well for web use, open-source projects, and many Android devices.

People often have MP4 files from screen recordings, phone videos, or online meetings. If you want just the audio, OGG gives you good quality at a smaller size compared to uncompressed WAV. The typical use case: you have a 4-minute MP4 (say, 40–60 MB for standard HD video) and want a music or speech track for editing, sharing, or archiving.

OGG is especially useful if you want to avoid MP3 licensing issues, or if you’re working with software (like Audacity, many Linux tools, or open web players) that natively support OGG. The format is also supported by Firefox, Chrome, VLC, and most Android music apps. It’s less common on iOS and older Windows Media Player builds, so check your playback needs.

If you need just the audio from your video, you can also extract audio from formats other than MP4, or trim the audio after conversion.

MP4 vs OGG: what’s the difference?

Property	MP4	OGG
Extension	.mp4	.ogg
Type	Video + audio container	Audio container (Ogg Vorbis)
Typical size (4 min)	40–60 MB (video+audio)	4–5 MB (audio only, q5 VBR)
Compression	H.264 video, AAC audio (lossy)	Vorbis audio (lossy, variable bitrate)
Quality	Up to 320 kbps audio, HD/4K video	About 160 kbps VBR audio
Device support	Nearly all devices & browsers	Most browsers, Android, VLC, not all iOS

MP4 is a multimedia file format that can contain video, audio, and even subtitles. OGG, or more precisely Ogg Vorbis, is a container and codec designed purely for audio. Converting from MP4 to OGG removes video and saves only the audio stream, recompressed to a modern, open format.

What does this MP4 to OGG conversion actually do?

This preset uses FFmpeg to extract the main audio track from your MP4 and encode it to Ogg Vorbis at quality 5. That’s roughly 160 kbps, variable bitrate—good enough for music or speech without obvious artifacts. There’s no bitrate slider or extra options. The video stream is dropped entirely. If your MP4 has multiple audio tracks, only the main one is used.

A typical 4-minute MP4 with stereo audio and video (say, 50 MB total) will become a 4–5 MB OGG file. That’s a 10x size reduction, mostly from discarding the video. The audio quality is similar to a 160 kbps MP3, but OGG can sometimes sound a bit better at the same bitrate.

If you need a lossless copy of the audio, OGG is not the right choice—try FLAC instead. This tool is for making lightweight, playable audio files for the web, mobile devices, or open-source projects.

When should you NOT convert MP4 to OGG?

Don’t use this conversion if you need to keep the video or subtitles. OGG only holds audio. If you want a lossless audio file, or need maximum compatibility (especially on iOS or in Windows Media Player without extra codecs), OGG may not be ideal. Use MP3 or WAV for universal playback.

If your project requires chapter markers, album art, or multi-track audio, OGG supports some but not all of these features. For simple voice or music, it’s a solid choice. But always check your target device or player first. For Apple devices, M4A (AAC) is often better supported.
