PDF merging uses pdf-lib — a JavaScript library that runs entirely in your browser. Your sensitive documents are never uploaded to any server, making this the most private PDF merger available online.
Frequently Asked Questions
How many PDFs can I merge at once?
There is no limit. Upload as many PDF files as needed and arrange them in any order.
Will the merged PDF lose quality?
No. PDF merging is completely lossless — all text, images, links, fonts and formatting are preserved exactly as in the original files.
Is there a file size limit?
Since merging happens in your browser, the limit depends on your device's memory. Files up to 50MB each work well on most computers.
Can I merge password-protected PDFs?
No. You need to remove the password protection first before merging. Most PDF readers allow you to save a copy without password.
