How to merge
- 1
Add your PDFs
Drop two or more PDF files onto the tool, or click to browse. Each page appears as a thumbnail — loaded straight into your browser, never uploaded.
- 2
Arrange the pages
Drag the page thumbnails into the order you want. You can rotate or delete any page, and add more PDFs at any time.

Download the merged PDF
Click “Download PDF”. The combined document is built on your device and saved instantly — no sign-up, no watermark.
Why use Merge PDF?
100% private
Your PDFs are processed entirely in your browser. Nothing is uploaded, stored or seen by anyone — even large or confidential documents stay on your device.
No limits, no watermark
No page caps, no daily limits, no sign-up, and never a watermark — unlike most online PDF tools.
Visual page editing
See every page as a thumbnail. Drag to reorder, rotate with one click, or delete the pages you don’t want — then download.
Works on any device
No install and no account. It runs in any modern browser on Windows, macOS, Linux, Android or iPhone.
Combine PDFs without uploading them
Most “merge PDF” websites upload your files to their servers, which is a problem for contracts, statements, ID scans and anything confidential. LocalTools merges everything locally in your browser using JavaScript, so your documents never leave your device. There are no page limits and no daily caps — the only ceiling is your device’s memory.
More than just merging
Because every page is shown as a thumbnail, you can fine-tune the result while you combine: drag pages from different files into a custom order, rotate a sideways scan, or drop pages you don’t need. What you see in the grid is exactly what the downloaded PDF will contain.
Frequently asked questions
Are my PDFs uploaded to a server?
No. Every page is read, rearranged and written entirely in your browser. Your PDF never leaves your device, so it works even offline once the page has loaded — ideal for confidential documents.
Is there a limit on the number or size of PDFs?
There’s no fixed limit. Because merging happens on your own device, the practical limit is your device’s memory — typical documents combine instantly.
Can I reorder or rotate pages while merging?
Yes. Drag thumbnails to reorder, use the rotate buttons on any page, and delete pages you don’t want before downloading.
