Going from OGG to FLAC locks in the quality you have now, it does not recover what was lost when the file was first encoded. That is still the right move before editing, because FLAC will not add a second round of compression damage. Budget for the size jump: about 1.6 MB per minute becomes roughly 6 MB per minute.
This conversion buys reach. FLAC is natively supported on 4 additional platforms compared with OGG, which is usually the reason people convert in this direction.
This conversion moves the file toward a different purpose: OGG suits game audio, open-source projects, web delivery, whereas FLAC is chosen for long-term archiving, audiophile listening, CD ripping.
Converting OGG to FLAC means moving audio out of the Ogg container, introduced in 2000, and into FLAC, which arrived in 2001. The two were designed with different priorities, and that is what determines whether this conversion costs you quality, storage, or compatibility.
Developed by Xiph.Org Foundation in 2000, OGG stores audio using Vorbis. That codec choice sets the upper bound on what any conversion can preserve.
FLAC, from Xiph.Org Foundation and dating to 2001, uses FLAC and plays natively on 5 of the six platform categories we track. That combination is usually why people convert into it.
