FAQ
Questions about merge PDF
Is there a limit on how many files I can merge?
No. The practical ceiling is your device's available memory, since everything runs locally — in normal use that means hundreds of files without trouble.
Does merging reduce quality?
Not at all. Pages are copied across intact rather than re-rendered, so images stay at their original resolution and text remains selectable and searchable.
Can I merge password-protected PDFs?
Remove the password first with the Unlock PDF tool, then merge. An encrypted file cannot be read into the merge without its password.
Is Merge PDF really free?
Yes — every tool on PDF Love is free, with no account, no email, no trial period, and no watermark stamped on your output. There is no file-count limit and no daily quota.
What happens to my files?
They never leave your device. This tool runs entirely inside your browser using WebAssembly, so your file is read from local memory, processed locally, and handed straight back. Nothing is uploaded, which is why it still works with your Wi-Fi switched off.
Is there a file size limit?
There is no limit imposed by us. Because the work happens on your own device, the practical ceiling is your available memory — comfortably a few hundred megabytes on a normal laptop or phone.
Does it work on a phone or tablet?
Yes. The site is built mobile-first and works in any modern browser on iOS, Android, Windows, macOS, and Linux. There is nothing to install.
