Frequently asked questions
Can the watermark be removed?
The watermark is drawn into each page of the new PDF, which makes it much harder to remove than a simple annotation.
Are my files safe?
Yes. With Helpdf, your files stay on your device. They are never sent to our servers, nobody else can see them and nothing is stored.
Is Helpdf free?
Yes, every tool is completely free with no sign-up and no watermark. The site is funded by advertising.
Does it work on phone?
Yes. Helpdf works in any modern browser on Android, iPhone, iPad, Windows, Mac and Linux. Very large files may be slower on older phones.
