About this tool
Merging PDFs is the quickest way to turn scattered documents into one tidy file: a CV with its cover letter, scanned receipts for an expense claim, or all the chapters of a report. PDFly copies every page from each file into a new PDF without re-compressing anything, so text stays sharp and searchable and images keep their original quality.
You can add as many files as you like and reorder them with the arrows before merging. Because the work happens inside your browser, even confidential contracts or ID documents are never sent to a server.

Questions about Merge PDF
Is there a limit to how many PDFs I can merge?
No fixed limit. You can merge dozens of files; the only constraint is your device's memory for very large documents.
Will merging reduce the quality?
No. Pages are copied as they are, so text, fonts, vector graphics and images are identical to the originals.
Can I merge password-protected PDFs?
Not directly. Open the file with its password and save an unprotected copy first, then merge it.
