How to convert URL to MP3
Extracting audio from an online video or stream requires fetching the media from the URL, separating the audio track, and encoding it as MP3. This is a common workflow for saving podcast episodes that lack direct RSS downloads, archiving online lectures and conference talks, or extracting the audio from video tutorials for offline listening.
This converter fetches the media from the URL you provide and encodes the audio as MP3 in your browser. Because the download happens client-side via WebAssembly, the resulting MP3 is processed on your device rather than stored on a server. Note that this tool works with direct media URLs (ending in .mp4, .webm, .ogg, or similar); it does not bypass platform-specific access controls or download restrictions.
Paste the media URL
Enter the direct URL of the video or audio file. This should be a link that directly loads the media file, not a webpage containing an embedded player. Direct URLs typically end in .mp4, .webm, .m4v, .ogg, or .m4a.
Select the audio quality
Choose the MP3 bitrate. 128 kbps is sufficient for speech content like lectures and podcasts. 192 kbps is better for music or content where audio quality matters.
Fetch and convert
The converter downloads the media to your browser memory, extracts the audio track, and encodes it as MP3 using WebAssembly. The download speed depends on the source server and your connection.
Download the MP3
Once complete, download the MP3 file. Verify playback and trim any unwanted silence from the beginning or end using an audio editor.
Frequently asked questions
Can I use this to download audio from YouTube?
YouTube serves video through dynamic streaming URLs with authentication tokens, not direct media URLs. This converter does not work with YouTube or similar platform-protected streams. It works with direct media file URLs that are publicly accessible.
What kinds of URLs work with this converter?
Direct links to media files served over HTTP or HTTPS. Examples: podcast episode .mp3 links, direct video .mp4 files hosted on web servers, publicly accessible .webm or .ogg audio streams. If your browser can play the URL directly by pasting it into the address bar, this converter can likely process it.
Is the audio downloaded to a server?
The media is fetched by your browser and processed locally in WebAssembly. The resulting MP3 is not stored on any server. However, the source media is fetched via your IP address, which is visible to the source server.
The URL loads the media in my browser but the converter fails. Why?
Cross-origin restrictions (CORS) prevent the browser from fetching media from some servers. If the server sends a CORS header that blocks cross-origin requests, the converter cannot access the file even if your browser can play it directly.
