How to Add a Watermark to PDF Online
Add a text or image watermark to PDF files directly in your browser with EDITHUBS. Use a watermark to mark a document as confidential, draft, approved, copyrighted, or branded. Choose the watermark content, adjust its size, position, opacity, and rotation, select the required pages, and download the updated PDF without installing extra software.
Upload the PDF you want to watermark
Click Select PDF file and choose a document from your device, or drag and drop it into the upload area. You can add watermarks to reports, contracts, invoices, proposals, certificates, forms, presentations, manuals, and other supported PDF documents.
Choose a text or image watermark
Select a text watermark when you want to display words such as Confidential, Draft, Approved, Sample, or Copyright. Choose an image watermark when you need to add a company logo, stamp, brand mark, signature, or custom graphic.
Enter and format watermark text
Type the watermark message and use the available controls to adjust its font, size, color, weight, or style. Keep the wording clear and short so it remains easy to recognize across different PDF pages.
Upload and resize an image watermark
When using an image, choose a clear file with suitable dimensions. Resize it so it fits naturally on the page and does not hide important text, signatures, tables, diagrams, or other document content.
Set the watermark position
Place the watermark in the center, corner, top, bottom, or another available position. A centered watermark is useful for document status, while a corner watermark works well for logos, ownership marks, and branding.
Adjust opacity, size, and rotation
Use opacity to control how strongly the watermark appears. Adjust its size for visibility and rotate it horizontally, vertically, or diagonally depending on the document design and the purpose of the watermark.
Choose which pages receive the watermark
Apply the watermark to the complete PDF or select only the pages that need it. Page selection is helpful when a cover page, appendix, signature page, or certain document sections should remain unchanged.
Preview and review the watermark
Check the watermark on different pages before saving. Make sure it is readable, correctly aligned, consistent in size, and transparent enough to preserve the visibility of the original PDF content.
Apply changes and download the PDF
When the watermark looks correct, apply the changes and download the updated PDF. Open the result for a final check, rename the file if needed, and keep the original document as a backup.
