FLAC vs MP3
| FLAC | MP3 | |
|---|---|---|
| Compression | Lossless, about half of WAV's size | Lossy, adjustable bitrate |
| Device support | Growing, but not universal | Supported everywhere |
| Typical source | Lossless music stores, CD rips | Everyday downloads and streaming |
Picking a bitrate for lossless source audio
Since you're starting from a lossless file, the bitrate you pick is the only thing that determines how close the MP3 gets to the FLAC. 320 kbps is the closest match, 256 kbps is very close for most ears, and 192 kbps or below trades noticeably more detail for a smaller file.
Batch converting a music library
If you're clearing out a folder of FLAC albums to save space on a phone or a portable player, drop the whole folder's files in at once. Each track converts independently at the bitrate you set, and the download all option packages the results as a single ZIP so you can unpack them straight into a music folder.
FLAC to MP3 FAQ
Why won't my FLAC files play on my phone?
Some music apps and older phones do not support FLAC, while MP3 plays on nearly everything, including basic media players and car stereos.
Will converting lose quality?
FLAC is lossless, so converting to MP3 is the first quality loss in the chain. 256 or 320 kbps keeps it close to the original for most listening, especially on phone speakers or earbuds.
How much smaller will the file be?
FLAC albums often shrink to a third or less of their size once converted to MP3, since FLAC itself is already only about half the size of the original WAV.
Where do FLAC files usually come from?
Music purchased from lossless stores like Bandcamp or HDtracks, CD rips, and some audiophile download sites that sell FLAC alongside or instead of MP3.
Should I keep the FLAC files after converting?
If storage space allows, yes. Keep the FLAC as your archive copy and use the MP3 for phones and everyday listening, since you can't get back to FLAC quality from an MP3.
Can I convert a whole folder of FLAC tracks?
Yes. Drop them all in and download the results individually or as one ZIP.
When was FLAC created?
The format dates back to 2001, and has been maintained by the nonprofit Xiph.Org Foundation as a free, open alternative to proprietary lossless formats ever since. It's still widely used today for music archiving.
Is my music uploaded?
No. The conversion happens on your device.
