Convert any PDF to CBZ directly from a URL
Pass a ?url= parameter pointing to any publicly accessible PDF and the converter opens it instantly — no upload step, no file picker. The PDF is fetched server-side, so browser CORS restrictions never get in the way.
How to use
Single PDF
The page fetches the PDF from that URL and opens the converter with it pre-loaded, ready to configure and convert.
https://mytools.com/pdf/pdf-to-cbz/by-url?url=https://example.com/my-comic.pdf
Requirements
| Protocol | http:// or https:// |
| Content-Type | application/pdf or application/octet-stream |
| Source | Any publicly accessible URL (no authentication supported) |
Server-side fetch · No CORS restrictions · PDF never stored on disk
Why use the by-URL entry point?
Skip the Upload Step
If your PDF is already hosted somewhere — a CDN, a GitHub release, a cloud storage bucket — pass the URL directly and jump straight to conversion.
No CORS Restrictions
The server fetches the PDF on your behalf, so browser same-origin rules never block the request. Any public URL works, regardless of the host's CORS policy.
Shareable Conversion Links
The URL is the session — share the by-url link with a colleague and they land directly on the converter with the same PDF pre-loaded.
Fits Automated Workflows
Build the URL programmatically in a script, CI step, or no-code automation tool. No browser interaction needed to get the converter loaded.
Same Converter, Different Entry Point
All the same settings are available — image format, quality, page range, grayscale. The by-url route is just a faster way in when you already have a link.
No Re-Download, No Re-Upload
When the source PDF lives online, fetching it via URL is faster than downloading it yourself and re-uploading it — one step instead of three.
Build the URL
Start with /pdf/pdf-to-cbz/by-url, then append ?url= followed by the full address of your PDF.
The PDF loads automatically
The server fetches the PDF from the URL you provided and opens the converter with it pre-loaded — no file picker, no drag and drop.
Configure and download
Adjust any settings (format, quality, page range, grayscale), click "Convert to CBZ", and download your .cbz file.
- PDFs are never stored — fetched and forwarded in a single request.
