Guide
Why merge PDFs
Merging PDFs shouldn’t mean installing desktop software or running into a two-file limit. This tool combines as many PDFs as your project needs, right in the browser — whether that’s a set of scanned pages, a stack of reports, or a folder of forms that all need to travel as one document.
Unlimited files
Combine as many PDFs as your project needs — there’s no artificial cap on file count.
Drag to reorder
Arrange pages by dragging thumbnails, and rotate anything upside down without re-scanning.
No quality loss
Pages copy over as-is, so your text stays selectable and your images stay just as sharp.
Do more after
Compress, split back apart, or add a signature to your merged PDF, all in the same session.

Security & privacy
What happens to your file
Your files are used once, then removed
Uploads are used to produce your merged download — they aren't kept afterward unless you save to a workspace.
No account required to merge
Upload, arrange, and download without creating an account.
Files aren't shared or indexed
What you upload stays private to your session — it isn't visible to other users or reused for anything else.
FAQ
Frequently asked questions
?Is merging PDFs online free?
Yes. Upload, arrange, and download — no account required.
?How many PDFs can I merge at once?
As many as you need. Very large files just take a bit longer to process.
?Will merging reduce quality?
No. Pages keep their original text and image quality.
?Do bookmarks survive merging?
Existing bookmarks carry over, but double-check them after reordering pages — they can end up pointing to the wrong page.
?Can I merge password-protected PDFs?
Remove the password first using Remove PDF Password, then merge as normal.
?What if one file is corrupt?
That file will fail with an error instead of breaking the whole merge — just re-export it and try again.
?Are my files stored after merging?
No, not unless you choose to save to a workspace. Otherwise files are removed after you download.
?Can I merge on mobile?
Yes, though desktop is easier for reordering a lot of pages.
