Merge PDF Files Online — Free & Fast

Combining scanned pages into a single application, stitching together chapters of a report, or assembling a set of invoices into one file — merging PDFs is one of those tasks that comes up constantly and shouldn't need a paid tool or an account. This one runs entirely in your browser: drop in your files, drag them into the order you want using the up/down controls, and merge. The combined file downloads immediately, and nothing is ever uploaded to a server along the way.

Frequently asked questions

How many PDFs can I merge at once?
There's no fixed limit — add as many files as you need. Everything runs on your device, so there's no upload cap to enforce.
Can I control the order of the merged pages?
Yes — files merge in the order they're listed. Use the up/down arrows next to each file to rearrange it before merging.
Are my PDFs uploaded anywhere?
No. The merge happens entirely in your browser in a background thread; your files never leave your device.
Will merging affect the quality or content of my PDFs?
No — pages are copied as-is into the combined document, with no re-rendering or recompression that could degrade text, images, or formatting.
Does this work with password-protected PDFs?
Not yet — remove the password first (or use the unlock-pdf tool, coming soon) before merging a protected file.
