Merge PDFs without uploading them

Merge PDFs

Choose two or more PDFs. They are joined into one file in the order listed below. Use the arrows to change the order before merging.

How to merge PDFs here

1. Add your PDFs with the box above. Nothing is uploaded; the files are only read by this page.
2. Order them with the Up and Down buttons. Pages appear in the merged file in exactly this order.
3. Click Merge PDFs. The combined file, named merged.pdf, downloads to your device.

Why merging without uploading matters

The PDFs people merge most are often the ones they least want on a stranger's server: contracts, tax forms, invoices, medical letters, and scans of ID documents. A server based merger asks you to trust its storage and deletion promises. A browser based merger removes that question entirely, because the file never travels. You can check for yourself: open your browser's developer tools, watch the Network tab while you merge, and you will see no request carrying your file anywhere.

Two honest limits: a PDF that needs a password to open cannot be merged, and very large files are limited by your device's memory, since everything happens inside the tab.
