About this tool

Merging PDFs is useful when you need to send one document instead of several attachments, such as contracts and addendums, monthly receipts, book chapters, or documents requested for an application.

Unlike other sites, your files are never uploaded to a server. They’re merged right in your browser, making the process faster and safer for personal or confidential documents.

Frequently asked questions

Is there a file or size limit?

We don't impose a limit. Since everything runs on your device, the only limit is your device's memory—most computers can merge hundreds of pages with ease.

Does merging change the PDF quality?

No. Pages are copied without recompression, so text, images, and internal links remain identical to the originals.

Can I merge password-protected PDFs?

PDFs with an open password need to be unlocked first. Use the Unlock PDF tool, then merge them as usual.

Are my files uploaded to a server?

No. This tool runs entirely in your browser: your file is read and processed on your device, and not a single byte is sent over the internet. You can even disconnect from the internet after the page loads.

Is it really free? Is there a daily limit?

It's free with no daily limits. Processing happens on your device, so there's no per-use cost and no need to limit you.

Does it work on phones?

Yes. The site works in any modern browser on Android, iPhone, Windows, Mac, and Linux—no installation needed.
