Watermark PDF: protect and identify your documents
A watermark shows where a document comes from or what its status is: "Confidential", "Draft", "Copy" or your company name. With ConverteJá you apply the watermark to every page at once, using text or an image.
You can customize font, size, format, transparency and rotation, so the mark is visible without getting in the way of reading.

When to use this tool
- Marking business proposals and contracts as confidential.
- Identifying early versions with the word "Draft".
- Applying the company logo to marketing materials.
- Discouraging misuse of documents shared outside the company.
Tips for a good result
- Use high transparency so the document text remains readable under the mark.
- A diagonal rotation, around 45°, is the most traditional and makes it harder to simply crop the mark out.
- For logos, use a PNG image with a transparent background.
Frequently asked questions
Can the watermark be removed later?
It is applied to the generated PDF, but no watermark replaces other security measures. To restrict who can open the file, combine it with Protect PDF.
Can I use my logo as a watermark?
Yes. Upload a PNG or JPG image and adjust its size on the page and its transparency.
Does the watermark appear on every page?
Yes, it is applied automatically to every page of the document.
What are the limits of the free plan?
The free plan allows 10 conversions per day, with files up to 60 MB and no sign-up required. The Premium plan removes the daily limit and the ads.
