WAV to MP3 Conversion FAQ
What bitrate does the MP3 file end up at?
+
A lossy MP3 is encoded at 192 kbps by default. The Audio Quality setting also offers 320 kbps for the best quality and 128 kbps for a smaller file. A lossless MP3 (WAV, FLAC) ignores the bitrate and keeps every sample.
How much quality do I lose converting WAV to MP3?
+
Some, and it is permanent — this is the one direction where information is genuinely thrown away. WAV holds every sample exactly; MP3 discards what a psychoacoustic model predicts you will not hear. At 192 kbps and above that prediction is good enough to be transparent on most material and most equipment. Keep the WAV as your master, because you cannot get back to it from the MP3. WAV normally stores raw uncompressed PCM — every sample kept exactly, at whatever bit depth and sample rate was captured. MP3 is lossy: a psychoacoustic model discards frequencies the ear is unlikely to notice, typically at 128 to 320 kbps.
Can I tag the MP3 with artist and album information?
+
Yes, and it is a genuine gain over WAV, which has nowhere dependable to store any of it. MP3 carries title, artist, album, year, track number and embedded cover art in the container itself, so a music library files it correctly without a manual pass. Nothing beats MP3 for compatibility — car stereos, gym equipment, DAPs and twenty-year-old hardware all read it without question.
Will going from WAV to MP3 actually reduce my audio quality?
+
If WAV is lossy (MP3, AAC) and MP3 is lossless (WAV, FLAC), the MP3 is no better than the WAV — you cannot recover information already discarded by the lossy WAV codec. If WAV is lossless and MP3 is lossy, expect the MP3 encoder to recompress; at 192 kbps the loss is imperceptible to most ears.
Can I batch-convert hundreds of WAV files into MP3?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Can I normalize loudness in the WAV to MP3 step?
+
Not in this step. The converter has no loudness setting and leaves the level as it is. To even out the volume, run the finished MP3 through a Normalize tool on this site.
Will the MP3 play on my car stereo / iPod / Sonos / Bluetooth speaker?
+
MP3 plays almost everywhere. AAC plays on Apple devices, most Android phones and Sonos. FLAC plays on Sonos and Android but not on older iPods, and WAV plays on nearly everything but makes large files. There are no device presets on this page, so choose the target format your player supports. MP3 is technically outclassed by AAC and Opus at every bitrate, cannot store more than two channels usefully, and always adds a small encoder delay.
Is my WAV file private during conversion?
+
Yes. Uploaded WAV files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted MP3 are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
How long does converting a 1-hour WAV to MP3 take?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
