Merge PDF
Combine PDFs and images into one PDF, in the order you choose.

How it works
- Drag to reorder files before merging; the result follows the list order.
- Mix PDFs with JPG, PNG or WebP images — each image becomes an A4 page.
- Pages are copied, not re-rendered, so text stays selectable and quality is unchanged.
- PDFs with only print/copy restrictions open without a password.

Are my files uploaded?
No. This tool runs inside your browser on this device. ORDO's servers never receive the file, and the page's security policy blocks it from sending file data anywhere.
Is there a file or page limit?
There is no fixed limit. Very large batches are limited by your device's memory.
What about password-protected PDFs?
PDFs that need a password to open can't be merged. Remove the password first, then merge.
