Stamping FAQs

Frequently Asked Questions

1 Does adding a watermark change or corrupt existing PDF text?
No. The tool adds the text or image overlay as a separate, clean vector layer. Your document layout, embedded fonts, and existing structures remain completely untouched and uncorrupted.
2 What type of images can I upload for watermarks?
You can upload standard image formats including PNG, JPG, and SVG. We highly recommend transparent PNGs or vector SVGs to achieve the most professional visual output for logos or signatures.
3 Can I apply the watermark to only the first or last page?
Yes, our page range controls allow you to specify exactly which pages to watermark. You can target specific indices (e.g., page 1 only) or skip standard introduction headers.
4 Is my original PDF document safe and secure?
Yes, safety is fully guaranteed. Since our processing engine executes directly in your browser viewport, we never transmit your raw documents over the internet.
5 Can someone easily remove the watermark using editing tools?
By default, standard overlays can sometimes be targeted by advanced editor software. For ultimate tamper prevention, we suggest running your PDF through our PDF Flattening tool after applying the watermark.
