No. No AI model touches your audio - the conversion is fully deterministic. The same input and target format always produce the same output.

Will converting lose quality?

WAV and FLAC targets are lossless. MP3, M4A, and OGG are compressed formats, so converting to them re-encodes the audio and, when the source was already compressed, some quality is lost. Keep your originals if you may need them again.

What happens to album art and video?

Embedded cover art and any video stream are dropped in the re-encode, so you get clean audio only. The output is a single-codec file named after the original upload.

Yes. Conversion runs on our own servers, your files are never sent to a third party or used for training, and everything is auto-deleted 7 days after the job finishes.

Convert Opus to MP3

Audio → MP3 · WAV1 credits per file

Opus is the format behind WhatsApp and Telegram voice notes, and most players and editors still won't open it. Export the notes, drop them in as a batch, and get back one MP3 per note, named after the original, ready to play, share, or send to a transcription tool.

Who uses this tool

PODCASTING

Masters any host accepts

WAV or FLAC masters become MP3s that podcast hosts and upload forms with size limits accept without complaint.

VOICE NOTES

iPhone memos that open anywhere

m4a voice memos convert to MP3 so they play in editors, players, and systems that still refuse m4a.

MUSIC & AUDIO

Archive without losing quality

Convert WAV session bounces to FLAC to shrink a library on disk while staying bit-for-bit lossless.

EDUCATION

Lecture audio students can play

Recordings saved in odd formats become MP3s that drop straight into a course page or an LMS.

LEGAL & COMPLIANCE

Recordings in one file format

Standardize a mixed pile of interview and call recordings to a single format for the case or matter file.

CUSTOMER SUPPORT

Call recordings, standardized

Export call audio from different systems and convert the whole batch to one format your QA tools read.
