About MP3 to FLAC
Convert MP3 files to FLAC (Free Lossless Audio Codec) container format in your browser. Note: this wraps the audio data in a FLAC container but cannot restore audio quality lost during the original MP3 compression. The result is a FLAC file, but it will not have true lossless quality –only the quality of the source MP3. This conversion is useful when software or workflows require FLAC input format. For true lossless audio, record or obtain the original uncompressed source. Processing happens entirely in your browser using FFmpeg.
Frequently Asked Questions
Will this improve audio quality?
No. Converting MP3 to FLAC wraps the audio in a lossless container, but the quality remains that of the original MP3. You cannot recover data lost during MP3 compression.
Why would I convert MP3 to FLAC?
Some software or hardware only accepts FLAC input. This conversion ensures format compatibility without re-encoding through a lossy codec.
Will the FLAC file be larger?
Yes, typically 2-3x larger than the MP3, since FLAC uses lossless encoding of the decoded audio stream.
