Add a watermark to a PDF

Yes. Choose a PNG or JPG image, then adjust its width, opacity, rotation, and position before applying it to the selected pages. Use an image with enough resolution for the intended size but avoid an unnecessarily large asset. Transparent PNG artwork can be useful for logos or stamps, while JPG always has a visible rectangular background. Preview the watermark over both light and dark page content and confirm that it remains legible without hiding information that readers need.

Yes. Enter individual page numbers or ranges, or leave the page selection empty to apply the watermark everywhere. Selective watermarking is useful for covers, confidential sections, draft pages, or specific exhibits. Verify that every requested page exists and check the first and last page in each range. If a document contains mixed page sizes or orientations, inspect representative pages because the same size and placement can appear different across the document.

Open the result and inspect every selected page type, including pages with dark backgrounds, dense text, signatures, diagrams, and different orientations. Confirm wording, spelling, image choice, opacity, rotation, size, color, and position. Make sure the watermark is visible at normal viewing and print size but does not obscure required content. A visual watermark is not access control or proof of ownership by itself, so apply any separate distribution or document-security requirements independently.

PNG and JPG watermark images are supported, along with text watermarks. Password-protected PDFs are not supported. One size, position, opacity, and rotation can look different across mixed page dimensions, orientations, and backgrounds. Watermarks do not automatically provide access control, ownership proof, or tamper detection. Some interactive features may not survive saving. Review every selected page type and confirm that required content remains readable.

Yes. Every PDF action listed in this section is free to use, requires no signup, and does not add a PetexSpace watermark. The tools have different input requirements and limitations, so open the exact action and review its page selection, supported image type, output behavior, and document warning before starting. Keep the original PDF until the result has been opened, checked page by page, and tested in the reader or workflow that will receive it.
