02About
What is Base64 to URL?
Base64 data URIs are handy inside code, but they're long, they bloat HTML and JSON, and many apps won't accept them. Converting one into a hosted file gives you a short, normal URL.
Decoding happens in your browser. If the input is a data: URI, its declared type is used. For raw Base64, the file type is detected from the first bytes, recognizing PNG, JPEG, GIF, WebP, PDF, ZIP, MP3, MP4, and more.
Popular uses

Replace a huge inline image in HTML, CSS, or email with a short URL.
- Debug API output

- Canvas exports
Turn a canvas.toDataURL() result into a shareable image link.
03Features
Why use this Base64 to URL tool
Type detection
The file type comes from the data: prefix or the file's own signature bytes.
Forgiving input
Line breaks, spaces, URL-safe characters, and missing padding are handled.
Links that clean up after themselves
Every upload is deleted automatically after 24 hours or 7 days, so nothing lingers.
No account, no email
Upload and share straight away. There's nothing to sign up for or log in to.
HTTPS everywhere
Uploads and links use encrypted HTTPS connections from end to end.
04FAQ
Base64 to URL: frequently asked questions
How do I convert Base64 to an image URL?
Paste the Base64 string or data:image/… URI and select Create link. The tool decodes it, detects the image type, uploads it, and gives you the URL.
What if the type can't be detected?
The file is uploaded as generic binary data (application/octet-stream), and the link downloads it. Add a data:<type>;base64, prefix to set the type yourself.
Is Base64 encryption?
No. Base64 is an encoding that anyone can reverse. Don't treat it as a way to protect sensitive data.
How long does the link last?
You choose: 24 hours or 7 days. After that the file is deleted automatically and the link stops working. Links can't be extended. Upload the file again for a new link.
Who can see my upload?
Anyone who has the link. Links are long and random, so they can't be guessed, but anything you share can be forwarded. Don't upload passwords, ID documents, or other sensitive data.
Is it free? Do I need an account?
Yes, it's free, and no account, email, or sign-up is needed. Each file can be up to 100 MB, and the service limits how many uploads you can make in a short time.
Can I delete a link before it expires?
Not from this page yet; every link is removed automatically after its lifetime (at most 7 days). To report content that breaks the rules, use the contact page.
