About OGG and FLAC

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 FLAC?

FLAC compresses audio without losing a single bit, usually to about half the size of WAV. It is the favorite format of audiophiles and music archivists: you get perfect CD (or hi-res) quality with proper tags and cover art, at the cost of files several times larger than MP3.

  • Lossless: identical to the original
  • About half the size of WAV
  • Full tags and cover art
  • Much larger than MP3
  • Not supported by some car stereos and older devices

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 FLAC reduce quality?

FLAC is lossless, so nothing is lost — but if the source is a lossy format (OGG), the result cannot sound better than the original; it will only be bigger.

Are song titles, artists and cover art kept?

Yes, where FLAC 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.
