Question 1

How do I merge PDF files for free?

Accepted Answer

Upload two or more PDF files to our free PDF merger. Drag and drop to rearrange their order, then click download to get your single merged PDF document. All processing happens in your browser.

Question 2

Can I merge PDF without login or sign-up?

Accepted Answer

Yes! PdfImageEditor is 100% free with no login required. Just upload your PDFs, merge them, and download — no email, no account needed.

Question 3

Is my data safe when I merge PDFs online?

Accepted Answer

Absolutely. Your files never leave your device. All PDF merging happens locally in your browser using WebAssembly. We never upload your files to our servers.

Question 4

Is there a limit to how many PDFs I can merge?

Accepted Answer

You can merge up to 50 PDF files at once. For the best performance, we recommend a total combined file size of under 100MB, as larger sets may be slower on some devices.

Question 5

Can I rearrange pages before merging?

Accepted Answer

Yes! After uploading, you can drag and drop the files to change their order. You can also use our more advanced PDF Editor to move, rotate, or delete individual pages before final merging.
