About this tool
What Merge PDF does
Merge PDF combines two or more PDF documents into one file in the order you select them. The browser reads each document, copies its pages into a new PDF, and downloads the result without adding a watermark or transferring the files to a server.
Practical example
A realistic way to use it
Combine a two-page cover letter, a three-page proposal, and a one-page terms document to create one six-page client package.
Know before you use it
Supported workflow and limitations
- Password-protected input PDFs may need to be unlocked first.
- Very large documents depend on the memory available to the browser.
Common questions
Merge PDF FAQ
Does merging add a watermark?+
No. Talzo does not add a watermark to the merged PDF.
Can I control the file order?+
Yes. Add files in the order you want; remove and re-add a file if the sequence needs changing.
Are my PDF files uploaded to Talzo?+
No. Talzo processes your PDF files inside your browser. The private input is not sent to our server.
Will bookmarks and forms always survive?+
Page content is copied, but complex document-level features may not transfer exactly. Review the final PDF.
Is there a file-size or usage limit?+
Talzo does not add an artificial usage gate. Practical limits depend on your browser, available memory, file complexity, and device performance.
