About Convertir Audio a MP3

Convertir Audio a MP3 brings together tools to convert, compress, trim and join audio files, transcribe recordings and extract audio from local videos.

Why it exists

The project started to help with everyday voice-note and recording tasks without installing an editor: making an MP3 copy, selecting a segment or joining several clips.

Who develops it

I am Mario Cepeda, a full-stack developer. I develop these tools and welcome suggestions and problem reports through Contact.

How it is built

The application uses FastAPI and FFmpeg to process files on the server. You use it from your browser without registering. Each operation has its own processing and temporary-file cleanup workflow.
