ToolzyLab
Add text or image watermarks directly to PDF pages with full control over style, opacity, size, position, rotation, tiling, and page range — fully local in your browser.
Protect documents, mark drafts, brand reports, add logos, insert copyright labels, or apply confidential stamps across PDF pages. Use text or image watermark mode and export your final file instantly.
Choose one or more PDF files and add a professional watermark.
Preview shows approximate watermark placement before export.
A text or image watermark can identify a draft, client copy, confidential packet, or branded proof, but it is not access control. Set content, opacity, rotation, scale, position, layout, offsets, page range, and draw order from the actual page preview, then check both light and dark pages before saving the marked copy.
Labels such as Draft, Confidential, Sample, or a recipient name are easiest to scan when concise. A transparent PNG logo can preserve brand shape without a solid box. Avoid adding sensitive personal data unless the distribution workflow requires it, because the watermark becomes part of every selected page in the exported file.
A centered diagonal mark is difficult to miss but can interfere with tables and signatures. A corner mark is quieter but easier to crop. Draw above content for reliable visibility or behind content for a restrained effect only when the PDF page is not opaque. Test pale pages, photographs, dark diagrams, and scanned pages rather than judging one representative sheet.
A review label may belong on every page, while a branding mark may be appropriate only on selected sections. Repeating or tiled watermarks increase resistance to simple cropping but also raise visual noise. Preview mixed page sizes and rotations, and keep an unwatermarked original because this tool produces a new marked copy rather than an editable watermark layer.
Inspect several kinds of pages before the file is shared outside the intended group.
Yes. Choose image watermark mode and use a suitable PNG, JPG, or WebP source supported by the control. A transparent PNG usually blends most cleanly; inspect edges and scale on several pages.
Choose the lowest opacity that remains readable over the document's lightest and darkest content. There is no universal percentage, so preview photographs, scans, and text-heavy pages before saving.
Above-content placement is more consistently visible but can cover details. Behind-content placement is subtler and may disappear beneath opaque page artwork. Select by purpose and inspect the actual pages.
Yes. Use the page-selection or custom-range controls and verify the first and last affected pages. This is useful when appendices, forms, or already marked pages should remain unchanged.
No. It communicates status or identity and may discourage casual reuse, but it can be covered or removed. Keep source records and use password protection or controlled sharing when access is the real concern.
This workflow writes a new watermarked PDF rather than maintaining an editable project layer. Keep the original clean PDF so you can produce another version without attempting to erase marks from page content.
