Question 1

Is this PDF merger tool completely free?

Accepted Answer

Yes, the PDF merger is 100% free with no hidden charges. There are no sign-ups, watermarks, or usage limits. You can merge as many PDFs as you need.

Question 2

Is there a file size limit?

Accepted Answer

There is no hard file size limit since all processing happens in your browser. However, very large files (over 100 MB combined) may be slower depending on your device's memory and processing power.

Question 3

Is it secure? Are my files uploaded anywhere?

Accepted Answer

Your files never leave your device. All merging is done entirely in your browser using client-side JavaScript. No data is sent to any server, making it completely private and secure.

Question 4

How many PDF files can I merge at once?

Accepted Answer

You can merge as many PDF files as your browser can handle. There is no artificial limit on the number of files. For best performance, we recommend merging up to 20-30 files at a time.
