Frequently Asked Questions
Will the PDF file lose quality after merging?
No. PDF Merge copies the pages as they are, without compressing or changing the content.
Is there a file size limit?
There is no hard limit because processing is in the browser. However, very large files (>100MB) can slow it down.
What if the PDF file is password protected?
Encrypted PDFs might not be readable. Please remove the password before merging.
