Frequently asked questions
Is it safe to merge PDFs online?
Yes. JustUse.me processes files entirely in your browser using JavaScript. Your PDFs are never uploaded to any server, so they stay completely private.
Can I merge more than two PDFs at once?
Absolutely. You can combine up to 20 PDF files in a single merge. Just drop them all in and reorder as needed.
Will merging reduce the quality of my PDFs?
No. The merge process combines files without re-encoding, so your text, images, and formatting stay exactly the same.
