Merge PDFs without uploading them
You can merge several PDFs into a single document without uploading any of them. LocalSign loads each file in your browser, lets you arrange the pages, and exports one combined PDF — no server involved.
Why this is useful
Merging usually means combining related, often confidential documents — statements, scans, reports. Most online “merge PDF” tools upload every file to do the work. Merging in the browser means all of those files stay on your device, and the combined result is built locally with the original pages copied (not re-rendered), so quality is preserved.
How to use it
- Open the Organize tool and drop in two or more PDFs.
- Drag pages into the order you want, across files.
- Optionally rotate, delete, duplicate, or insert blank pages.
- Download the merged PDF — built in your browser.
Good to know
- Interactive form fields can collide; bookmarks/outlines and metadata may not be preserved.
- Encrypted PDFs may fail to load.
- Combining many large files depends on browser memory.
FAQ
Are my PDFs uploaded?
No. Each file is read locally in your browser and the merge happens on your device.
Can I reorder pages across different files?
Yes — the page grid lets you drag pages from any file into any order.
Is there a hard page or file limit?
No fixed limit, but very large merges depend on your device’s available memory.
Privacy & honesty
