Why use this tool

Merges as you add

There is no merge button. The combined PDF rebuilds automatically whenever you add, remove, or reorder a file.

Nothing leaves your browser

The whole merge runs locally in your browser. Contracts, statements, and scans are never uploaded anywhere.

No quality loss

Pages are copied as-is into the new document: text stays selectable, images keep their resolution, nothing is re-compressed or rasterised.

No watermark, no signup

The output is a clean PDF with no branding, and there is no account or daily quota.

As many files as your device can hold

There is no fixed cap on file count or size; your browser memory is the only practical limit.

About this tool

This PDF merger combines any number of PDF files into a single document without sending them anywhere. It runs entirely in your browser, and it merges continuously: the moment a second file is added the combined PDF exists, and every reorder or removal rebuilds it in place. There is nothing to wait for and no queue to sit in.

The common cases are the boring ones: stitching a signed contract back together with its annexes, combining a stack of scanned receipts for an expense report, or assembling chapters exported separately into one submission. Because pages are copied rather than re-rendered, the merged file behaves exactly like the originals: selectable text, working links, full-resolution images.

If you need the opposite operation, the split PDF tool extracts page ranges into separate files. To drop specific pages before merging, use delete PDF pages, and to stamp numbering on the combined result, add page numbers. Image collections can become a PDF first with images to PDF.

Frequently asked questions

How do I merge PDF files?
Drop two or more PDF files onto the tool or click to browse. They are combined into one PDF the moment a second file is added. Use the up and down arrows to reorder files before downloading, then click Download to save the merged PDF.
Are my PDFs uploaded to a server?
No. The whole merge happens locally in your browser. Your files never leave your device, are never uploaded, and are not stored or logged anywhere.
Can I change the order of the files?
Yes. Each file in the list has up and down controls so you can arrange them in any order. The merged PDF rebuilds instantly whenever you reorder or remove a file.
Is there a limit on the number or size of PDFs?
There is no fixed limit, but because everything runs in your browser, very large files use your device memory. Most everyday documents merge in a second or two; extremely large scans may take a little longer.
Will merging reduce the quality of my PDF?
No. Pages are copied as-is into the new document, so text stays selectable and images keep their original resolution. Nothing is re-compressed or rasterised.
