Frequently asked questions
Can I watermark only some pages?
Yes. Choose “Some pages” and enter page numbers or ranges.
How do I add a watermark to a PDF?
Open the PDF, type the text, for example CONFIDENTIAL or DRAFT, set the font, color, transparency, angle and position, and click “Add watermark”. The preview updates as you change each setting.
Can I use my logo as a watermark?
Yes. Choose an image instead of text and place it in one of nine positions, or repeat it across the page as a mosaic.
Can the watermark sit behind the text?
Yes. Place it below the content and it appears behind the text like a background, or leave it over the content to mark the page more strongly.
Can someone remove my watermark?
With the right software, yes. A watermark deters casual reuse but isn’t protection. Combine it with Protect PDF, and use Redact PDF for anything that must not be shared at all.
Is it really free?
Yes. There is no sign-up, no daily limit and no watermark added to your files.
Are my files uploaded to a server?
No. ModifyPDF processes files with JavaScript inside your browser. Your documents never leave your device, and nothing is stored after you close the page.
Text or image watermarks
Stamp text such as CONFIDENTIAL or DRAFT with your choice of font, size, color and rotation, or place a logo image. Pick one of nine positions or a mosaic that repeats the mark across the page, and set the transparency.
Pages and layering
Apply the watermark to every page or a page range. Place it over the content, or below it so it sits behind text like a background.
Why add a watermark
Marking a draft so it isn’t mistaken for the final version, labeling a document CONFIDENTIAL before sharing it, branding a portfolio or report with your logo, or discouraging reuse of sample pages.
Watermarks are a deterrent, not protection
A determined person can remove or crop a watermark with the right software. For real protection, combine it with Protect PDF, and use Redact PDF for information that must not be shared at all.
