Merge PDF
Combine two or more PDF files into a single document, in the order you choose.
What it does
Merge PDF takes the PDFs you drop in and writes them out as one document, in the order you arrange them. Pages are copied across untouched — the same text, the same fonts, the same image data — so the result is not a re-export or a re-print of your originals.
When you need it
Usually when something has to be sent as a single attachment: a signed contract split across separate scans, a set of invoices for one month, or chapters that were drafted separately and now need to read as one file.
Limits and caveats
There is no page or file-count limit, but merging holds every document in memory at once, so very large scans are bounded by your device rather than by us. Bookmarks and form fields from the source files are not carried over. Everything happens in your browser, so the file never leaves your device.

Frequently asked questions

- No hard limit — merging runs in your browser, so it depends on your device's memory.
- Do my files get uploaded?
- No. This tool runs entirely in your browser, so the file never leaves your device.
