Frequently asked questions
Is there a file limit?
No fixed limit — very large files depend on your device’s memory.
Can I merge password-protected PDFs?
Remove the password first; locked PDFs can’t be combined.
Are my files uploaded to a server?
No. Everything happens inside your browser using your own device. Files are never uploaded, stored or seen by anyone — you can even switch off the internet after the page loads and the tool keeps working.
