Convert audio files to and from MP3 online with bitrate control and optional edits.
MP3 remains the most compatible audio format across devices and platforms. Shrinkify lets you convert locally and fine tune bitrate to balance file size and sound quality.
Convert WAV or FLAC to MP3 for smaller files, or batch convert multiple audio tracks for uploads and sharing.

| Option | Best For | Tradeoff |
|---|---|---|
| MP3 | Wide compatibility | Less efficient compression than some modern codecs |
| AAC/M4A | Better quality at same bitrate | Slightly less universal playback |
| WAV | Editing and archival | Very large file size |
Why it happens: Bitrate too low for source complexity
Fix: Increase bitrate and reconvert from original
Why it happens: Trim settings remained active
Fix: Disable trim when full-length conversion is required
Theory: Lossy and lossless formats trade compatibility, size, and fidelity differently.
When to use: Use MP3/AAC for delivery, WAV/FLAC for editing or archive flows.
Common mistake: Converting lossy-to-lossy repeatedly from previously compressed sources.
Theory: Cut points near transients can sound abrupt.
When to use: Trim around natural pauses and verify first/last seconds.
Common mistake: Cutting exactly on visible waveform peaks without listening.
Theory: Loudness balancing improves consistency but can raise noise floor.
When to use: Normalize after all edits are complete.
Common mistake: Applying gain early and clipping after later edits.
Theory: Global settings speed up output but can overfit one content type.
When to use: Group files by speech/music type before batch jobs.
Common mistake: Using one bitrate profile across very different recordings.

Pick bitrate by content type: speech vs music.
Using very low bitrate for music causes metallic sounding highs.
