On iPhone, converted files save to your Files app. Tap the download link and choose where to save.
OGG is lossy. Converting to FLAC won't restore lost data, but gives you an uncompressed container for editing workflows. The output is identical regardless of which device or browser you use.
Frequently Asked Questions
Will the FLAC sound better than the OGG?
No. FLAC is a lossless container, but the audio inside is whatever your OGG decoded to. If the OGG was encoded at 96 kbps Vorbis, you're wrapping 96-kbps-quality audio in a lossless container — the FLAC will sound exactly like the OGG. The only audible difference would come from re-encoding, and we don't do that. FLAC just gives you compatibility, not better quality.
How much larger will the FLAC be?
Typically 5–7× the OGG size at common Vorbis bitrates (160–192 kbps). A 5 MB OGG track becomes a 25–35 MB FLAC. The FLAC stores the full decoded waveform losslessly, while OGG only stored the parts the psychoacoustic model thought you'd hear. Hi-quality OGGs (Q8+, 256 kbps) compress closer to 3–4× when re-wrapped as FLAC.
Does this work with OGG Opus, not just Vorbis?
Yes. The converter detects whether the OGG container holds Vorbis or Opus and decodes accordingly. Both end up as bit-identical FLAC because both are decoded back to PCM before re-encoding.
Will tags transfer from OGG to FLAC?
Yes — both formats use Vorbis comments for metadata (FLAC inherits this from its Xiph.Org lineage). Title, artist, album, track number, year, and embedded album art all transfer cleanly. This is one of the main wins of OGG → FLAC over OGG → MP3 (which has to convert Vorbis comments to ID3 tags).
Is FLAC the right archive format for OGG sources?
It is the right neutral container. But understand that 'archiving lossy audio in a lossless format' doesn't add quality — it just freezes what you have. If you want a true high-quality archive, re-rip the source from CD or buy a lossless purchase. If you only have the OGG, FLAC at least guarantees no further generational loss.
Should I just keep the OGG instead?
If file size matters and your playback devices read OGG (Android phones, VLC, web browsers, most Linux apps), keep the OGG. Converting to FLAC only makes sense when you specifically need FLAC compatibility — audiophile player, DAW, archive consolidation, hardware that lists FLAC support.
About OGG
Open-source compressed format. Better quality than MP3 at similar bitrates. Used in gaming and web applications.
About FLAC
Lossless compression. Perfect quality at roughly half the size of WAV. The choice for audiophiles and archiving.
