Compress large WAV recordings and masters into compact MP3 files for listening, sharing, and publishing. No signup, no software, and local browser processing for files from your device.
Drop a WAV or another supported file here to convert, or import from:
WAV stores uncompressed samples and is ideal for production, but it is often unnecessarily large for review links, websites, phones, and everyday playback. MP3 reduces that delivery size with a selected bitrate.
The converter estimates the resulting file size from track duration and bitrate, and batch mode processes up to 10 WAV files sequentially in the browser.
Upload WAV or another supported source while this workflow keeps MP3 as the destination format.
Convert one file or process up to 10 tracks sequentially, then download individual MP3 files or a ZIP.
Choose compatible encoding settings, retain detected source parameters where possible, and estimate the MP3 size before conversion.
WAV-to-MP3 conversion removes audio data to reduce file size. Keep the original WAV if you may need to edit or master the audio again.
Keep the WAV master, select a delivery bitrate, review the estimated size, and create a separate MP3 copy.
Drop one file into the uploader, or choose Batch Convert for up to 10 files. Source formats and technical details are detected automatically.
Choose the available MP3 settings or keep compatible source parameters, then review the estimated output size.
Start sequential browser processing, preview a single result, or save batch files individually or together in a ZIP archive.
Choose this format direction when MP3's compatibility or workflow fit matters more than keeping the original WAV container.
Make a smaller copy of a WAV mix, interview, lesson, or recording for email and messaging.
Create a widely supported MP3 for websites, review links, and portable playback.
Keep the WAV master archived and use the MP3 copy on phones, cars, and music players.
These recommendations are specific to WAV sources and MP3 delivery rather than generic conversion advice.
Use 128 kbps for spoken audio, 192 kbps for general listening, and 256-320 kbps for a high-quality review or music copy.
MP3 is a delivery format, not a production replacement. Archive the original WAV for later edits, mastering, or new exports.
The size estimate is based on duration and selected bitrate, making it easier to plan a batch before starting the encoder.
The formats solve different delivery needs. Keep the source when you may need its original quality or metadata, and create MP3 as the working or listening copy.
| Format detail | WAV | MP3 |
|---|---|---|
| Format type | uncompressed PCM audio | lossy compressed audio |
| Typical file size | Large | Small |
| Quality model | Lossless when created from a lossless source | Lossy |
| Best used for | Editing, DAWs, mastering, transcription, and production handoff | Everyday playback, sharing, websites, cars, and older devices |
| Compatibility | Excellent in editors and desktop software | Near-universal |
At any common delivery bitrate, MP3 is normally much smaller than uncompressed WAV. The selected rate determines the final trade-off.
Add a WAV file, confirm MP3 as the output, select Convert Audio, and download the finished file. The conversion runs in your browser for files chosen from your device.

Files selected from your device are decoded and encoded locally in the browser. Imports from a link, Dropbox, or Google Drive first use the selected provider and configured import service.
Single files are limited to 200 MB. Batch mode accepts up to 10 files or 500 MB total and processes them sequentially to reduce browser memory pressure.
Yes. Switch to Batch Convert, add up to 10 supported files, and download each MP3 result separately or together in a ZIP archive.
Yes. MP3 remains the output for this focused page, but the uploader accepts every supported audio source and MP4 audio input. Use the main Audio Converter to choose a different output.
A 44.1 kHz, 16-bit stereo WAV uses about 1,411 kbps before container overhead. A 192 kbps MP3 is typically around one seventh of that data rate.
No. 128 kbps is often enough for speech, 192 kbps works for general listening, and 256-320 kbps is better suited to high-quality music copies.
Convert MP3, WAV, M4A, FLAC, OGG, AAC, AIFF, WMA, Opus, and AMR, with optional MP4 audio input and ALAC output.
Convert MP4, MOV, AVI, MKV, WEBM, FLV, or WMV entirely in your browser.
Detect monophonic pitch, clean up timing, transpose notes, preview the result, and export a standard MIDI file.
