FAQ
Is there a file size or page limit?No hard limit from us — since everything runs in your browser, the practical limit is your device's memory. Most PDFs, even long ones, merge and split without issue.
Do you store or see my files?No. Files are processed entirely client-side and never transmitted anywhere. Closing the tab clears everything.
Do I need to sign up or install anything?No account, no browser extension, no software download. It works in any modern browser.
Can I merge PDFs in a specific order?Yes — files list in the order you add them, so add or remove them until the order is right before merging.
Does this work on mobile?Yes, the tool works on mobile browsers, though merging very large files is easier on a device with more memory.
