Convert WAV to MP3 Online

WAV files capture studio-quality audio but can be ten times larger than MP3. SeerKits converts WAV to MP3 in your browser so you can email voice memos, publish podcasts, and save phone storage without installing desktop software. All processing runs locally on supported browsers — your recordings never leave your device. Choose bitrate presets from 128 kbps for speech to 320 kbps for music.

How It Works

How to convert WAV to MP3 with SeerKits

  1. 1

    Upload your WAV file

    Select a .wav file from your device. SeerKits displays duration and file size before conversion.

  2. 2

    Set MP3 quality

    Pick an MP3 bitrate preset. Higher bitrates preserve more detail; lower bitrates produce smaller files for voice recordings.

  3. 3

    Download MP3

    Convert and save the MP3 file. Trim highlights afterward with Audio Cutter if you only need a segment.

Frequently Asked Questions

How much smaller is MP3 compared to WAV?
A typical WAV file at CD quality (44.1 kHz, 16-bit) is roughly 10 MB per minute. The same audio as 192 kbps MP3 is about 1.4 MB per minute — a 7× reduction.
Will WAV to MP3 conversion lose quality?
MP3 is a lossy format, so some detail is removed compared to uncompressed WAV. At 256–320 kbps, the difference is imperceptible for most listening scenarios.
Can I convert multiple WAV files at once?
The free web tier supports small batches per day. For folder-scale conversion with metadata preservation, use Seer Audio on desktop.
Are my audio files uploaded to SeerKits servers?
No. Audio conversion runs locally in supported browsers. Your tracks stay on your device with no signup required.
