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
Nothing to install. It runs in the browser on your phone or computer.
The output settings are written on the page, so you know what file you will get.
Uploads can be up to 80 MB and 60 minutes.
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.
