Are my PDF files uploaded anywhere?

No. The merge runs entirely in your browser using pdf-lib, so your PDFs never leave your device.

How many PDFs can I merge at once?

There is no hard limit because nothing is uploaded. Very large or numerous files depend only on your device's available memory.

Can I choose the order of the files?

Yes. You arrange the PDFs before merging, and their pages are combined in exactly that order.

Does merging keep every page of each PDF?

Yes. Every page of each source PDF is copied into the combined document, so nothing is dropped.

Will the quality of my PDFs change?

No. Pages are copied as-is into the new document, so text, images, and formatting are preserved.

Is there a watermark or sign-up?

No. The tool is free with no watermarks, no account, and no file-size paywall.

Does it work offline?

Yes. Once the page has loaded, you can merge PDFs even without an internet connection.

Merge PDFs without uploading them

Joining several PDFs into one file makes it easy to send a full contract, a set of statements, or a bundle of scanned pages as a single tidy document. This tool copies every page of each PDF you add into one combined file, keeping the exact order you set. It runs with pdf-lib directly in your browser, so sensitive paperwork like contracts and bank statements never leaves your device — nothing is uploaded to any server.

How to merge PDF files

Add your PDFs Drag and drop the PDF files you want to combine, or click to select them from your device.
Arrange the order Reorder the files so the pages appear in the sequence you want in the final document.
Merge locally The pages are copied and stitched together in your browser to build one combined PDF.
Download Save the merged PDF to your device — no account or upload required.

Your PDFs stay private

All processing happens directly in your browser. Your PDF files are read and merged on your own device and are never uploaded to any server, so contracts, statements, and other sensitive documents stay with you. We collect only anonymous, aggregated usage statistics (such as how often a merge starts or succeeds) to improve the tool — never your files, filenames, or any personal data.

Verify it yourself: Open your browser DevTools → Network tab and run the tool: no request ever carries your file. Everything happens on your device.
