Frequently asked questions

Does opening a PDF send it to a server?

No. The reader loads the file in your browser only.

Do I need Adobe Reader or any download?

No. The viewer runs in the browser you already have, so you can read a PDF without installing Acrobat or a mobile PDF app.

Can I search or select text in the viewer?

No. Pages are rendered as images for fast, private reading, so there is no text search or text selection. Use PDF to Text if you need the wording out of the file.

Can I open large PDFs on mobile?

Yes, within your device’s memory. Very large files may feel slower on phones than on a desktop.

Can I edit after opening?

Yes. Use tools such as organize, annotate, or sign from the catalog.

Do I need an account to view a PDF?

No. There is no sign-up or login.
