Convert Audio & Video to MP3 — Free, Secure, No Upload

PDFGami's audio converter turns M4A, MP4, MOV, WAV, FLAC, AAC, OGG/Opus, WebM, and MP3 files into MP3 — entirely in your browser. The decoding uses your browser's built-in audio engine and the MP3 encoding runs locally via lamejs (a JavaScript LAME port), so audio data never travels to any server. Free, secure, with adjustable bitrate from 96 to 320 kbps, batch input, and ZIP download for multiple files. Useful for converting iPhone voice memos (M4A), extracting audio from YouTube downloads (MP4), shrinking studio WAVs, or trimming lossless FLAC libraries to a portable format.

Supports Many Formats

M4A, MP4, MOV, WAV, FLAC, AAC, OGG/Opus, WebM, and MP3 all decode natively in modern browsers. Drop any of them, get MP3.

100% In-Browser, Secure

No upload. The audio is decoded and MP3-encoded on your device — safe for voice memos, recordings, and other private audio.

Free, No Watermark

No signup, no email, no MP3 watermark, no monthly cap. Convert as many files as you want.

Bitrate Control

96 / 128 / 192 / 256 / 320 kbps. Pick the size-vs-quality trade-off that matches your use case.
