Can I watermark a PDF without uploading it?

Yes. The watermark is applied entirely in your browser using JavaScript, so your PDF never leaves your device. This makes the tool suitable for confidential drafts and client documents.

Can I use my company logo as a watermark?

Yes. The tool accepts PNG and JPEG images as watermarks. Your logo is embedded into the PDF and scaled to the placement and size you choose.

Can the watermark appear on only some pages?

Yes. Instead of all pages, you can enter a custom page range such as 1-3,5. Only the pages you list will receive the watermark.

Which placements are available?

You can place the watermark in the four corners, centered as a single large mark, or tiled diagonally across the whole page. Tiled placement is best for deterring screenshots.

Does watermarking change the PDF quality?

No. The watermark is added as a transparent overlay on top of the existing pages. Your original text, images and layout remain unchanged.

Is a watermark the same as PDF password protection?

No. A watermark is a visual mark; it shows ownership but does not prevent editing. Password protection stops a file being opened or modified. For sensitive files, use both.

Will the text in my PDF still be searchable after watermarking?

Yes. The watermark is a separate layer, so the underlying text remains selectable and searchable. Only the area covered by a dense watermark is harder to select visually.

What happens to scanned PDFs?

Watermarks work on scanned PDFs as well, because they are simply placed above the page image. If the scan is rotated, consider rotating the PDF first so the mark sits straight.

Is this tool free and is there a file limit?

The tool is completely free with no account and no watermarks added to your output. Processing happens locally, so very large files simply take a little longer.

Can I remove a watermark later?

A watermark that has been flattened into the page image is very hard to remove cleanly. Because this tool keeps the overlay separate, some editors can delete it - which is why a tiled mark or password protection is better for high-risk documents.

Can I add both a text and an image watermark?

Yes. Run the tool twice - once with your text mark and once with your image mark - so both overlays appear. This layered approach is a strong deterrent against casual copying.

Does the watermark print along with the document?

Yes. The watermark is part of the PDF page content, so it appears both on screen and in printed output. Tiled marks survive printing particularly well.

Can I watermark a scanned PDF?

Yes. Watermarks are added on top of the page image, so scanned documents work exactly like digital ones. Rotate the scan first if it is sideways so the mark sits straight.

Does a watermark reduce the PDF quality or size?

No. The watermark is drawn into the PDF as a clean overlay, so the underlying text and images keep their original quality. The file size changes only minimally.
