Merge PDF
Join multiple PDFs into one.
Runs entirely in your browser. Nothing you enter or upload leaves your device.
What the PDF merger does
The PDF merger joins separate PDF files into a single document, one after another in the order you set. It saves sending five attachments when one will do: a cover letter, CV and certificates for a job application, a year of bank statements, or pages that came off the scanner as separate files.
Each file is checked as soon as you add it, so you see its page count, and the total for all files, before anything is joined.
How to use the PDF merger
Join several PDF files into one document.
- Drop two or more PDF files.
- Use the arrows to put them in order. Each file shows its page count.
- Press Merge PDFs and download the result.
Understanding the results
The finished file is called merged.pdf, and its card shows the number of pages and the file size. Pages are copied across rather than redrawn, so text stays selectable and searchable, and pictures keep their original quality.
A file that is password-protected or can’t be read stays in the list with a short note beside it, but it is skipped when you merge. The button only becomes active once at least two readable files are in the list. The merged file starts as a new document, so it doesn’t take on the title or author details stored in your originals.
Questions
Can I merge password-protected PDFs?
No. Remove the password first; protected files are marked in the list and left out.
Is anything lost?
Pages, text and images are kept. Bookmarks and some form fields from the originals may not carry over.
Are my PDFs uploaded?
No. Merging happens in your browser.
How large can the files be?
There is no fixed limit on file size, but everything happens in your browser’s memory. Very large files (hundreds of megabytes) may be slow on phones. You can add up to 50 files each time you drop or choose them, and add more afterwards.
Can I remove a file I added by mistake?
Yes. Press the cross next to it. The page total updates straight away.
Can I merge just some pages of a file?
Use Split PDF first to extract the pages you need, then merge the results.
