How to convert MP3 to FLAC

1

Upload the MP3

Choose a .mp3 file from your phone or computer.

2

Pack it as FLAC

The converter writes a FLAC. There is no bitrate to pick, because FLAC stores the decoded samples without MP3 compression.

3

Download the FLAC

Save the FLAC when the conversion finishes.

Why convert MP3 to FLAC

Some tools refuse MP3 and ask for FLAC. This page decodes the MP3 and packs those samples in FLAC. The file gets larger. It does not sound clearer, because the MP3 encoder already removed detail.

What this page converts

Sites that require FLAC

Hand over a FLAC when an uploader will not take MP3.

Same sound, larger file

The FLAC is a lossless packing of the decoded MP3, not a remaster.

Archive copy

Keep a FLAC copy of a decoded MP3 if a workflow demands that container.

Deleted afterward

The upload and the result are removed from the server when the job ends.

Why use this converter

Quality notes

Use this when a tool demands FLAC. Do not use it to improve a low-bitrate MP3. The highs that were removed stay removed.

MP3 to FLAC questions

Is MP3 to FLAC free?

Yes. Upload a MP3 and download the FLAC with no account.

Will the FLAC sound better?

No. It sounds like the decoded MP3. FLAC only changes how the samples are stored.

Why is it bigger?

FLAC does not use MP3’s heavy compression, so the file grows even though the sound does not improve.

Is there a bitrate?

No. FLAC is lossless. This page does not offer an MP3 bitrate.

Are files kept?

No. The MP3 and the FLAC are deleted after processing.

Why did it fail?

The file may be over 80 MB or 60 minutes, protected, or not a real media file. Try another file.
