Your files never leave your device.

Merge PDF files without uploading them

Combine several PDFs into one, in the order you choose, right in your browser.

How it works

Pages are copied as they are into one new PDF, in the order you set, on your device. Nothing is recompressed, so text, images and links stay unchanged.

Why use this tool?

No uploads, accounts, ads, or tracking. The processing engine runs locally on your device.

Frequently asked questions

Can I change the order of the files?

Yes. Move files with the arrows, drag them with a mouse, or sort them by name before merging.

What is kept in the merged PDF?

Pages are copied as they are, so text, images and links stay unchanged. Bookmarks and fillable form fields are not carried over.

Can I merge password-protected PDFs?

Yes. Enter the password on the file in the list; it is unlocked on your device, and the merged PDF has no password.

How many files can I merge?

Up to 50 PDFs at a time. Very large files depend on your device's memory.

Are files uploaded?

No. Files stay in this browser tab and are never sent to a server, whichever tool you use.

Is it free? Are there limits?

Free, with no account, watermark or daily limit. The only limit is your device's memory for very large files.

Does it work on iPhone and Android?

Yes. Every tool runs in modern mobile browsers. Very large PDFs can exceed a phone's memory; a computer handles those better.

Does it work offline?

Yes, once you have used a tool online: the site keeps its files in the browser and then runs without a connection.
