Transform your large, lossless music library into portable MP3s for your phone or player.
Drag and drop your .FLAC music files. We support batch processing for whole albums.
Select 320kbps for the best quality, or lower if you need to save more space.
Get your new MP3 files instantly. They are ready to play anywhere.
Our converter attempts to preserve your ID3 tags (Artist, Title, Album) during the conversion process so your library stays organized.
FLAC is incredible for quality, but terrible for portability. A single album can take up 300MB. Our converter solves this by using the most efficient MP3 encoding algorithms available.
We use a Variable Bitrate (VBR) capable engine when possible, or high-quality CBR (Constant Bitrate) at 320kbps to ensure that complex musical passages retain their detail, while silence or simple sounds take up less data.
The result is an MP3 file that is universally compatible with every player, car stereo, and phone on the planet, using 1/5th of the storage space of your original FLAC.
Processing happens on high-speed servers and is deleted immediately.
MP3s work on 100% of devices. FLAC works on about 40%.
Supports up to 320kbps output
FLAC (Free Lossless Audio Codec) is amazing for archival. It creates a perfect copy of a CD. However, file sizes are massive, and many older car stereos, iPods, and cheap MP3 players simply cannot play FLAC files.
MP3 is the universal language of digital audio. By converting to MP3, you ensure that your music can be played on literally any device made in the last 25 years. Plus, you can fit 5x more songs on your phone.
We prioritize audio integrity. Many online converters simply forcefully change the file container, often resulting in glitchy audio. We:
Audio compression where no data is lost. The file is smaller than raw WAV, but sounds identical.
The file uses the same amount of data for every second of audio. Good for compatibility.
The amount of data processed per second. Higher bitrate (320kbps) means better quality.
The software used to compress or decompress digital audio (e.g., LAME, FLAC).
Honestly? Probably not. Unless you have $500+ headphones and a quiet room, 320kbps MP3 is indistinguishable from FLAC.
Always choose 320kbps if you want to keep as much quality as possible from your FLAC source.
Your files are processed in a dedicated secure environment and auto-deleted.
