Can I add a custom text watermark to my PDF?

Yes. You can type any text — CONFIDENTIAL, DRAFT, your company name, a project code, or any custom message. Font size, colour, opacity, angle, and position are all adjustable.

Will my PDF have PDFTash's watermark on it?

No. PDFTash never adds its own branding to your output file. The only watermark that appears is the one you create.

Can I remove a watermark from a PDF?

PDFTash has a separate Remove Watermark tool for PDFs where the watermark is a text/object layer. Image-based watermarks embedded in scanned pages cannot be removed without affecting the underlying image.

Does adding a watermark increase the file size?

Minimally. A text watermark adds only a few kilobytes to the file size — negligible for any practical purpose.

Q: Can I add a watermark to only some pages?

Yes. You can apply the watermark to all pages, only the first page, or specific page ranges — useful for marking just the cover or specific sections.

Frequently Asked Questions

Can I add a custom text watermark?

Yes. Type any text into the watermark field — CONFIDENTIAL, DRAFT, your company name, a project code, a client name, or any phrase. Font size, colour, opacity, rotation angle, and page range are all customisable.

Will my PDF have PDFTash's own watermark on it?

No. PDFTash never adds its branding to your output files on any plan. The only watermark that appears is the one you create with your custom text.

Can I add a watermark to only some pages?

Yes. You can watermark all pages, only the first page, only the last page, or a specific page range (e.g., pages 3–10). This is useful for branding just the cover page or marking appendices specifically.

Can I also remove a watermark from a PDF?

PDFTash has a separate Remove Watermark tool for text-layer watermarks. Note that watermarks embedded within scanned page images (printed on the original paper) cannot be removed digitally without affecting the underlying image.

Does adding a watermark change the file size?

Only minimally. A text watermark layer adds a few kilobytes to the file — imperceptible in any real-world usage. If file size is a concern, you can compress the watermarked PDF afterwards using PDFTash Compress.
