How to merge PDFs
- Add two or more PDF files.
- Drag the files into the order the final document should read.
- Untick any file to leave it out.
- Click Download PDF.
Tips
- Pages are copied without re-rendering. Text, fonts, images and page sizes stay the same.
- Remove blank pages or duplicate covers afterward with the page editor.
- If merged form fields misbehave, print each form to PDF first and merge the flattened copies.
FAQ
Is there a limit on how many PDFs I can merge?
No fixed limit. Dozens of typical documents merge fine; capacity depends on your device's memory.
Will the merged PDF keep the original quality?
Yes. Pages are copied, not re-rendered.
Do bookmarks and links survive the merge?
Page content always does. The bookmark sidebar may not, and links to page numbers can point to the wrong page.
Can I mix page sizes and orientations?
Yes. Each page keeps its own size and orientation.
Are my documents uploaded to merge them?
No. Your browser combines the files on your device.
