Merge PDF: frequently asked questions
How do I merge PDF files?
Select or drop your PDFs, drag them into the order you want, then press Merge PDF. Your combined file downloads straight away.
Is there a limit on how many PDFs I can merge?
No fixed limit. Very large sets (hundreds of megabytes) depend on your device’s memory, because the work happens in your browser.
Is it safe for confidential files?
Your file never leaves your device: hellpdf does this in your browser, so nothing is uploaded and there’s no file size limit beyond what your device can handle.
Is it really free?
Yes. It’s free with no sign-up, no watermark and no daily limit on the tools that run in your browser.
