Merge PDF

Why merge PDFs?

Related documents have a habit of arriving as separate files: a cover letter, a CV and a portfolio; three scanned receipts; the chapters of a report someone exported one at a time. Sending five attachments is clumsy, and whoever receives them then has to juggle five files. Merging stitches everything into one tidy PDF that opens, prints and shares as a single document. Add as many PDFs as you like, drag them into the order you want, and merge. When you need finer control, the Page Manager opens every page of every file as a grid, so you can rearrange pages across documents, drop the ones you don't need, rotate a page that came in sideways, and even slot in a blank page. Colour-coded chips keep track of which page came from which file. Merging copies your pages exactly as they are, so it stays lossless: the text remains selectable and nothing is re-compressed. It all runs in your browser, so your files never leave your device.

How do I combine multiple PDF files into one document?

Add your PDFs, drag them into the order you want (or open the Page Manager to arrange individual pages), then merge them into a single file. It copies the pages exactly as they are, so the result stays lossless, and the whole thing runs in your browser, so your files are never uploaded.

Frequently asked questions

Can I choose the order of the files?
Yes. Drag the files into the order you want, or nudge them up and down with the arrows. The merged PDF follows that order, top to bottom.
Can I rearrange or remove individual pages, not just whole files?
Yes, in the Page Manager. It lays out every page of every file as a grid, so you can reorder pages across documents, delete pages (with undo), rotate a page, and insert a blank one.
Does merging make the combined file smaller?
No. Merging copies the pages losslessly, so the result is roughly the size of the originals added together and the quality is untouched. If you need a smaller file afterwards, compress it. Compress a PDF
Can I merge a password-protected PDF?
Not while it's locked. Remove the password first, then merge the unlocked copy. Unlock a PDF
Is there a limit on how many PDFs I can combine?
You can add plenty of files; the practical ceiling is your device's memory, because everything is processed locally. Very large individual files (around 100 MB and up) may be rejected.
Are my files uploaded to merge them?
No. The PDFs are combined entirely in your browser, and nothing is sent to a server.
