Questions
Merge PDF FAQs
Does merging upload my PDFs?
No. Merge PDF reads files with the browser File API and builds the result in a same-origin worker on this device.
Can I mix page sizes in one merged file?
Yes. Each source page keeps its own dimensions. Letter, A4, and custom sizes can sit in the same output.
What happens if a file is password-protected?
Merge PDF rejects encrypted files with a clear error. Unlock that file first if you know the password.
