Frequently asked questions
Is the watermark tool free?
Yes. Adding a watermark to a PDF on PDFMax is completely free, with no account, subscription or signup required. Just open the tool and start.
Can I add a logo or image instead of text?
Yes. You can either type a text watermark like "Draft" or "Confidential", or upload your own logo or image to stamp onto the PDF.
Can I control the opacity and angle?
Yes. You can adjust opacity (transparency), rotation, size and position. A faded, slightly rotated mark around 20-40% opacity usually looks best so the text underneath stays readable.
Does it apply to all pages?
Yes. The watermark is applied across every page of your PDF, so the whole document is consistently marked before you share or print it.
Does it work on my phone?
Yes. PDFMax runs in your browser with no installation, so it works the same on Android and iPhone as it does on a laptop or desktop.
Is there a file size limit?
PDFMax handles typical everyday documents with ease. Very large or high-resolution PDFs may take a little longer to process depending on your device and connection.
