Frequently asked questions
How do I change the order of the files?
Drag pages by their handle, or use "Sort by file name". Each file has its own color dot so you can tell them apart.
Can I merge password-protected PDFs?
Remove the password first. Protected files can't be opened in the browser.
Is it safe to use for confidential documents?
Yes. Your files never leave your device: all processing happens locally in the browser.
Is there a page or file limit?
No fixed limit. Very large documents simply need a bit more time and memory on your device.
Can I combine PDFs and photos?
Yes. Mix PDFs and images freely; images become pages sized to fit, A4 or Letter.
Does rotating or merging reduce quality?
No. PDF pages are copied as they are, so text stays sharp and searchable.
