PDFs to merge
Page box: leave it empty for the whole file, or type 1-3, 7 to take only
those pages.
How it works
Add two or more PDFs and they are combined into a single document right inside your browser tab. The files are read with the PDF-lib library running locally on your device — nothing is uploaded, so contracts, invoices, bank statements and scanned ID documents never touch a server. Pages keep their original size, orientation and quality, because they are copied across rather than re-rendered.
Every file in the queue shows a thumbnail of its first page next to its name and page count, so you can tell similar scans apart and check the merge order without opening anything. Click a thumbnail to page through that document full size.
The PDFs are joined in the order shown in the list. Move any file up or down, drop one from
the queue, or sort the whole queue alphabetically — the merged result is rebuilt instantly
after every change. Each file also has a page box: leave it empty to take the whole document,
or enter pages and ranges like 1-3, 7 to pull only the pages you need. Set the
output name and download the finished PDF — free, with no watermark and no sign-up.
Frequently asked questions
How do I merge two PDFs without uploading them?
Drop the PDFs onto this page and they are combined locally by JavaScript running in your browser tab, and no file is ever sent to a server. Put them in the order you want with the up and down buttons, then click "Download merged PDF" to save the result.
Can I merge only some pages from a PDF?
Yes. Every file in the list has a page box. Leave it empty to include the whole document, or type pages and ranges like "1-3, 7" to take only those pages. The merged document is rebuilt instantly as you type, so you can see the new page count straight away.
Is there a file limit, and does the merged PDF get a watermark?
No watermark, no sign-up and no ads. The merged file contains only your pages. You can queue up to 40 PDFs of up to 80 MB each; the real limit is your device's memory, since all the work happens on your own computer. Password-protected PDFs must have their password removed first.
