How to convert CD to MP3
Audio CDs store music as uncompressed PCM audio at 44,100 Hz and 16 bits per sample, which is why a single album occupies 650 to 700 MB on disc. When you rip a CD to your computer, software like iTunes or Windows Media Player often produces WAV or AIFF files first. Converting those WAV files to MP3 reduces the size by roughly 10 to 1 at 128 kbps while keeping the audio perceptually close to the original, making the music practical to store and carry on a phone.
Upload the WAV or AIFF file ripped from your CD and this converter will encode it to MP3 directly in your browser using WebAssembly. The audio never leaves your device, no account is needed, and you can choose the exact bitrate that balances size against quality for your listening situation.
Rip the CD track to WAV first
Use any CD ripping software (iTunes, Exact Audio Copy, Windows Media Player) to extract the track as a .wav or .aiff file. Most rippers default to WAV, which is what this converter expects.
Upload the WAV file
Drop the ripped WAV file onto the converter. A typical four-minute CD track is about 40 MB as WAV; the file stays in your browser and is not uploaded to any server.
Choose the bitrate
192 kbps is a common choice for music converted from CD. It produces a file roughly 15x smaller than the original WAV while maintaining quality that is difficult to distinguish from lossless in controlled listening tests. 128 kbps halves the file size further with a modest quality trade-off.
Download the MP3
Once conversion completes, download the MP3. Verify playback on your target device. The original WAV can be deleted once you are satisfied with the MP3 quality.
Frequently asked questions
What bitrate comes closest to CD quality?
CD audio is 1,411 kbps of uncompressed data. MP3 at 320 kbps is the highest MP3 bitrate and passes most blind listening tests against the original. 192 kbps is where most listeners cannot reliably distinguish MP3 from lossless. Below 128 kbps, artifacts become noticeable on complex musical passages.
Should I use joint stereo or stereo in the MP3 encoder?
Joint stereo stores only the difference between the left and right channels instead of both independently, which improves quality at a given bitrate for most music. It is the correct choice for music at 128 kbps and above.
Is the audio uploaded to a server?
No. The conversion runs entirely in your browser via WebAssembly. No data leaves your device.
Can I convert directly from a CD without ripping first?
No. This converter works with files on your file system. You need to rip the CD to a WAV or other audio file using separate software before converting here.
Does the MP3 keep the track title and artist metadata?
WAV files rarely contain metadata. If your ripping software added ID3 tags or embedded a RIFF INFO chunk, the converter will attempt to carry those over to the MP3. For reliable tagging, use a dedicated tag editor after conversion.
