Merge & Split PDF — Without Uploading Anything
Every other PDF tool asks you to send your file to their server. This one doesn't. All processing happens inside your browser, on your own device. Your files never leave your computer — not even once.
Combine multiple PDF files into one, in any order you like.
Drag & drop PDF files here
or click to browse — select multiple files
Extract specific pages, or split one PDF into several.

🔒 Nothing is uploaded. Processing runs entirely in this browser tab. Disconnect your internet — these tools still work.
Why "local" matters more than you think
Server-based tools hold your data
When you upload a PDF to a typical online tool, that file sits on someone else's server — often temporarily stored, logged, or scanned. Contracts, bank statements, medical records, IDs: all of it passes through a third party.
Local is also faster
No upload wait, no download wait, no queue. A 200 MB file merges as fast as your own machine allows, because there's no round trip across the internet.
It works with no internet
Once this page is loaded, you can pull the network cable and keep working. That's only possible because nothing here depends on a server.
Nothing to leak, because nothing is collected
No accounts, no emails, no analytics on your documents, no "temporary copies." There is simply no server configured to receive your file.
How to merge PDF files
- Add your files. Drag them in or click to browse. Select as many as you need.
- Reorder if needed. Drag items in the list, or use the arrows, to set the page order.
- Click "Merge PDFs". Your browser combines them locally — usually in a second or two.
- Save the result. The merged file downloads straight to your device.
Splitting works the same way: choose a page range, or split every N pages into separate files.
Frequently asked questions
Is it really 100% local? Do my files get uploaded?
No. Nothing is ever uploaded. All processing happens inside your own browser using JavaScript. You can verify this yourself: open your browser's developer tools (F12), go to the Network tab, and watch — after the page finishes loading, zero requests are made while you work. You can even disconnect from the internet entirely and the tools keep functioning.
Why does this matter for sensitive documents?
Most online PDF tools require uploading your file to their servers, which means contracts, financial statements, medical records and IDs pass through someone else's computer. With local browser processing, sensitive documents never leave your machine.
Is there a file size or page limit?
No artificial limits. Because the work happens on your own hardware rather than a shared server, the only real constraint is your device's memory. Large files work fine on modern computers.
Do I need to create an account or pay anything?
No account, no payment, no email address. The Merge and Split tools are completely free, with no daily caps or watermarked output.
Which browsers are supported?
Any modern browser — Chrome, Edge, Firefox and Safari. It runs on desktop and mobile, though large files are more comfortable to handle on a desktop machine.
Will the quality of my PDF change?
No. Merging and splitting move existing pages between documents without re-encoding them, so text, images and formatting are preserved exactly as they are.
