Frequently asked questions

No. The PDF is opened and edited entirely in your browser, so your documents never leave your device. Nothing is stored or sent anywhere.

Up to 30 files at a time. Very large documents use more memory, so on phones it's best to keep the total under a few hundred pages.

No. Pages are copied as-is, so text stays selectable and images keep their original quality.

Page content, links and annotations are copied, but the combined file doesn't keep each document's bookmark outline, and form fields may stop being fillable.

Not yet. Encrypted PDFs can't be edited in the browser, so you'll see a message asking you to remove the password first.
