How to add a watermark to a PDF
Add a text or image watermark to every page of a PDF directly in your browser. Choose the watermark type, position, opacity, rotation, size, and margin, then download a new watermarked copy.
Add your PDF
Select one PDF from your device. Fylento checks the file and page count before applying the watermark.
Choose text or image
Enter watermark text such as “CONFIDENTIAL” or choose a PNG or JPG image to use as the watermark.
Customize and download
Set the position, rotation, opacity, size, and page margin, then create the watermarked PDF.
Text and image watermarks
The current tool supports both PDF text watermarks and image-based watermarks.
Text watermark
Add up to 80 characters of watermark text. Fylento uses bold Helvetica in dark gray and lets you choose a text size from 12 to 120.
Image watermark
Use a PNG or JPG image such as a logo or stamp. The image size can be set from 10% to 80% of the PDF page width.
Control watermark position and appearance
Fylento applies the same watermark settings to every page in the document.
Nine page positions
Choose top-left, top-center, top-right, middle-left, center, middle-right, bottom-left, bottom-center, or bottom-right.
Four rotation choices
Rotate the watermark by -45°, 0°, 45°, or 90°.
Adjustable opacity
Set opacity from 5% to 100% so the watermark can be subtle or fully visible.
Adjustable page margin
For edge positions, set the page margin from 0 to 100 to control how far the watermark sits from the page edge.
Watermarks are added directly to the PDF pages
Fylento loads the original PDF and draws the watermark onto each page. It does not intentionally turn every page into a flat image just to add the watermark.
Text remains PDF text
Text watermarks are drawn as PDF text using an embedded standard font.
Image watermarks keep their proportions
Image watermarks are scaled proportionally based on page width, so the watermark image is not stretched.
Add PDF watermarks privately in your browser
The PDF and optional watermark image are processed on your device. They do not need to be uploaded to a remote watermarking service.
Local PDF processing
Fylento reads, modifies, and creates the output PDF directly in the browser.
No Fylento watermark
Fylento adds only the watermark you choose. It does not add its own promotional watermark to the document.

Watermark PDF FAQ
Can I use my logo as a PDF watermark?
Yes. Choose Image mode and upload a PNG or JPG logo, then adjust its size, opacity, rotation, and position.
Is the watermark applied to every page?
Yes. The current tool applies the same watermark settings to every page in the selected PDF.
Can I change the watermark transparency?
Yes. Opacity can be adjusted from 5% to 100%.
Does adding a watermark flatten the PDF?
No. Fylento draws the new text or image watermark onto the existing PDF pages rather than intentionally rasterizing the whole document.
Does Fylento upload my PDF?
No. The current Watermark PDF tool processes the document locally in your browser.
