FAQ
Frequently Asked Questions
Google Slides keeps rejecting my FLAC soundtrack — what should I upload instead?
Convert the FLAC to MP3 and insert the new file; this is a compatibility step, not a repair. Use a higher bitrate for music, because the conversion shrinks the track by permanently discarding audio data.
I have a 90-minute concert recording and need a smaller file — what should I choose?
Choose the kbps bitrate based on your priority: lower for a smaller file, higher for fewer audible artifacts. The job runs in your browser with no account required, but a long track still needs to be re-encoded, so it may take a little time.
Can I convert FLAC to MP3 without losing any quality?
Every FLAC to MP3 conversion introduces some loss, because MP3 uses lossy compression. You can minimise it: choose 320 kbps, convert from the original FLAC, and use a reliable converter like this one, which relies on the latest LAME encoder.
If I convert FLAC to MP3 now, can I change it back later for editing?
You can create a lossless file later, but it will not restore the audio data discarded by the lossy encode. Keep the original file if you might edit, remaster, or archive the track.
Can I convert a large album folder, or is there a limit after a few files?
It is free and unlimited in practical terms: queue up to 20 tracks per run, with no usage counter or paid tier. There is no strict file-size cap, but very large audio files are still limited by your upload speed and re-encoding time.
Will my cover art, artist name, and track numbers survive the conversion?
This page is not a tag manager; the reliable controls here are bitrate and sample rate for the audio output. If those tags matter, check the downloaded file and fix the metadata in your library app before syncing.
