Is this MP3 converter free?
Yes. It is a completely free online MP3 converter with no signup and no watermark, and it runs in your browser with no upload required.
Can I upload MP3 to this converter?
No. This tool converts other formats into MP3. Existing MP3 files should go to the MP3 editing tools instead of this converter.
Which input formats can I convert to MP3?
WAV, M4A, AAC, OGG, FLAC, and WebM audio are the main intended inputs, covering most recordings, voice memos, and downloads.
Does conversion stay local?
Yes. The audio-to-MP3 conversion runs entirely in your browser with no server upload, so your file stays private on your device.
How do I convert audio to MP3 for free?
Open the file here, pick a bitrate, and export. WAV, M4A, AAC, OGG, FLAC and WebM audio all convert to MP3 in your browser, with no signup and no upload: the file is decoded and re-encoded on your device.
What bitrate should I choose?
192 kbps is the right default: transparent for speech and near-transparent for music on phones and earbuds. Use 128 kbps for voice notes and podcasts, and 256 or 320 kbps only when the source is lossless and it will be heard on real headphones.
Does converting to a higher bitrate improve the quality?
No. If the source is a 128 kbps MP3, exporting at 320 kbps just makes a larger file with the same information. The detail was discarded by the first encoder and no re-encode can bring it back.
Can I convert a YouTube link to MP3 here?
No. This converts a file you already have on your device. There is no URL field and nothing is downloaded from other sites.
Is anything uploaded to a server?
No. The audio is decoded and re-encoded in your browser, so the file never leaves your device. That is also why it works on a slow connection and on a file you would not want to hand to a website.
