How to merge PDF files

Drop two or more PDFs into the box (or click to choose).
Use ↑ and ↓ to put them in the order you want.
Click Merge PDFs and download the combined file.

Pages are copied exactly as they are, so text stays selectable and images keep their original quality. There's no file-count or size paywall.

Quick answers

Is it safe to merge confidential PDFs here?

Yes — the files are processed by your own browser and are never uploaded to a server.

Can I merge PDFs on my phone?

Yes, it works in mobile Chrome and Safari. Very large files depend on your phone's memory.

Is there a limit on files or size?

No paywall and no fixed limit — only your device's memory. Hundreds of pages merge fine on a normal laptop.

How to use PDF Tools

Pick a tab: Merge, Extract / delete / split pages, Rotate, or Images → PDF.
Drop your files in. Nothing is uploaded — the PDF engine runs in your browser.
Choose the pages or options, then download the new PDF.

Why use a private PDF tool?

Most online PDF tools upload your file to their server. Contracts, bank statements, invoices and ID scans shouldn't have to leave your device.
No sign-up, no file-size paywall, no watermark.
Fast: nothing to upload or download except the finished file.

Privacy

PDF Tools processes your files entirely in your browser using pdf-lib, an open-source PDF library (MIT license) loaded from jsDelivr. Only the library code is downloaded; your PDFs and images are never sent anywhere.

Frequently asked questions

Are my PDFs uploaded?

No. Merging, splitting, rotating and converting all happen inside your browser. QuickTiny never receives your files.

How do I write page ranges?

Use commas between items and a dash for ranges: 1-3, 5, 8- means pages 1, 2, 3, 5 and everything from 8 to the end.

Can it open password-protected PDFs?

Not yet. Remove the password in your PDF reader first, then use the tools here.

Does merging reduce quality?

No. Pages are copied as-is, so text stays selectable and images keep their original quality.

Is there a size limit?

There's no fixed limit; very large PDFs (hundreds of MB) depend on your device's memory.
