Questions
Does MP3 to FLAC make the audio lossless again?
No. It stores the decoded MP3 audio in a FLAC file, but it cannot restore details lost during MP3 compression.
Why export FLAC from MP3?
Some archives, players, and editing workflows require FLAC files. The shared local converter can also export MP3, WAV, or FLAC.
Does MP3 to FLAC upload audio?
No. The converter engine loads in your browser and creates the output locally.
Does Utilumo upload my input?
No. Utilumo has no backend that could receive your input. Where a tool makes a request as part of its function, it goes directly from your browser to the destination you choose, never through Utilumo.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
