✅ Merge

📎Add at least two PDFs to merge.

One file instead of five attachments

Merging is the quickest way to send a complete pack — a quotation with its terms, an invoice with the delivery note and signed LPO, or a visa application with every supporting document — as one tidy PDF in the right order.

Lossless, private merging

The merger copies each page object as-is into the new document, so text stays selectable and images keep their original resolution. Because it runs in your browser, confidential documents never touch a server.

FAQ

Frequently asked questions

Are my PDFs uploaded to a server?

No. Every PDF tool on Pyalm runs entirely in your browser using JavaScript — your files are read, processed and saved on your own device and are never sent to us or anyone else. That makes them safe for contracts, invoices and ID documents.

Is there a limit on files or size?

There is no fixed limit. The practical limit is your device's memory — dozens of files and a few hundred MB are fine on a modern computer.

Can I merge password-protected PDFs?

Unlock them first with the Unlock PDF tool (you need to know the password), then merge the unlocked copies.

Will links and bookmarks survive?

Page content, including link annotations, is preserved. Document-level bookmarks (outlines) from the source files are not carried into the merged file.
