Frequently Asked Questions
Are my PDF files uploaded to a server?
No. Merge PDF combines your files entirely in your browser. Your PDFs never leave your device.
How many PDF files can I merge at once?
You can merge up to 20 PDF files in one go, each up to 50MB.
Can I change the order of the files before merging?
Yes. Use the up and down arrows next to each file to arrange them in the order you want them to appear in the final PDF.
What happens to password-protected PDFs?
Password-protected or corrupted PDFs can't be read in the browser and will be rejected with an error so you can remove or replace them.
Will merging affect the quality of my PDFs?
No. Merge PDF copies the original pages into a new document without re-rendering them, so text, images and formatting stay exactly as they were.
