About OGG and MP3
What is OGG?
Ogg Vorbis is an open, royalty-free alternative to MP3 with somewhat better quality at the same size. Game engines like Unity and Godot use it widely, and so does a lot of open-source software. Apple devices and some players do not support it well.
- Open and royalty-free
- Better than MP3 at low bitrates
- Standard in game engines
- Limited support on Apple devices and car stereos
What is MP3?
MP3 is the most compatible audio format there is. It shrinks music to about a tenth of CD size by removing sounds people hardly hear. At 192–320 kbps most listeners cannot tell it from the original, and every device ever made with a speaker can play it.
- Plays on every device
- Small files
- Lossy
- Slightly less efficient than AAC or Opus
Why GlideConvert?
- Private by design. Your files are converted on your own device by your browser — they are never uploaded to a server. That keeps them private, avoids upload waits and means there is no queue.
- Fast. Images convert in a fraction of a second; video uses your device’s hardware encoder.
- Free. No sign-up, no watermark. 10 images, 5 audio files or one video at a time — Pro lifts the limits and removes ads.
Frequently asked questions
Will converting OGG to MP3 reduce quality?
MP3 is a lossy format. At 192 kbps (the default) the result is practically indistinguishable from the original for most listeners; pick 256–320 kbps for the best quality, or 96–128 kbps for speech and podcasts.
Which bitrate should I choose?
128 kbps is fine for speech and podcasts, 192 kbps is great for music, and 256–320 kbps is as good as it gets. Higher bitrates mean bigger files: roughly 1 MB per minute at 128 kbps and 2.4 MB at 320 kbps.
Are song titles, artists and cover art kept?
Yes, where MP3 supports them: title, artist, album, track number and similar tags are copied from the OGG file.
Is there a file size limit?
On the free plan each video or audio file can be up to 500 MB and each image up to 100 MB. With Pro the limit is 4 GB per file. Because everything happens on your device, the practical limit for very large files is your device’s memory.
Are my files uploaded to a server?
No. GlideConvert runs entirely in your browser: images are processed with the browser’s built-in codecs and WebAssembly, video and audio with hardware-accelerated WebCodecs (or a WebAssembly build of FFmpeg for older formats). Nothing is sent anywhere — you can even disconnect from the internet once the page has loaded.
Does it work on iPhone, Android, Mac and Windows?
Yes. It works in any up-to-date browser — Chrome, Edge, Safari, Firefox or Samsung Internet — on phones, tablets and computers, with nothing to install. On phones, extremely large images may be scaled down to fit within the browser’s memory limit; you will see a note if that happens.
