About Convertir Audio a MP3
Convertir Audio a MP3 is a collection of online tools to convert, trim, compress, and mix audio directly from your browser. It started with a simple idea: let anyone turn their audio into MP3 without installing software, registering, or wasting time.
The project homepage is convertiraudioamp3.com, where you can access the MP3 converter and the rest of the utilities.
Our approach
- No accounts or passwords: upload, convert, and download. That’s it.
- Privacy: audios are processed on the server and deleted automatically after a short time.
- All in the browser: optimized for desktop and mobile, no heavy installs.
- Real-life use cases: WhatsApp voice notes, meetings, interviews, videos, podcasts, and more.
Main tools
From the homepage you can access tools such as:
- Convert WhatsApp audios to MP3
- Convert video to MP3
- Mix audios online
- Trim audio online
- Compress MP3 files
- Transcribe audio to text
How it’s built
Technically, the project uses FastAPI for the web and API layers, and relies on FFmpeg for all audio/video processing. This combo enables fast, reliable conversions across many formats (OPUS, AMR, M4A, OGG, WAV, MP4, etc.).
Who’s behind it
My name is Mario Cepeda and I’m a full-stack developer. I like building useful tools that solve very specific problems: convert a tricky audio, trim an important meeting part, compress a file for sharing, and more.
Convertir Audio a MP3 was born from that need: a simple way to clean and convert audio without opening a heavy editor every time.
