Post an MP3 to Facebook directly from a URL.
Append a ?url= parameter to this page and the MP3-to-Facebook tool opens with your audio pre-loaded, ready for a cover image, a size, and your Facebook Page. The audio is fetched server-side, so CORS restrictions on the source host don't apply.
How to use
Single MP3
The page fetches the audio file on the server, opens the tool, and drops you straight into the configure step — pick a cover image and size, connect your Facebook Page, then post.

One MP3 per session
This tool posts one video at a time because video encoding is memory-heavy in the browser. The ?url= parameter accepts a single audio URL; additional ?url= values are ignored.
Requirements
| Protocol | http:// or https:// only |
| Content-Type | audio/* or application/octet-stream |
| Source | Any publicly accessible URL |
| Formats | MP3, WAV, M4A, AAC, OGG |
Server-side fetch · No CORS restrictions · Works with any public MP3 URL
Why post from a URL?
Skip the upload step
When your MP3 is already hosted somewhere — a CDN, Bandcamp, an RSS feed — pass the URL directly instead of downloading then re-uploading. The tool opens with the audio ready to turn into a Facebook video.
No CORS restrictions
The page fetches the audio file server-side, so cross-origin rules on the source host don't get in the way — even for files served without permissive CORS headers.
Shareable and linkable
The URL is the session. Copy it, send it to a teammate, and they'll open the exact same MP3 ready to post — handy for chat handoffs and tickets.
Fits into automated workflows
Generate the by-url link programmatically from a CMS, a publishing pipeline, or a bulk script so posting to Facebook becomes a drop-in step wherever you produce finished MP3s.
Great for podcast episodes
Paste an episode URL from your hosting provider and the tool opens instantly, ready to wrap it in a video with your show's logo and publish it to your Page.
Same tool, different door
Every option from the main tool — cover image, size presets, fit modes, title, and caption — works identically once the MP3 has loaded.
How it works
Build the URL
Start with /audio/mp3-to-facebook/by-url, then append ?url= followed by the full address of the MP3 you want to post.
The audio loads automatically
Open the URL in your browser. The server fetches the MP3 and the tool opens with the track ready, skipping the upload screen.
Connect Facebook and post
Choose a cover image and size, connect your Page, add a caption, then hit Post to Facebook.
