How do I add a watermark to a PDF online for free?

Upload your PDF, type your watermark text (or upload a logo), choose the position and opacity, then click Apply Watermark. The watermark is stamped on every page and you can download the result immediately.

Can I add a logo image as a watermark to a PDF?

Yes. Switch to the Image Watermark tab, click to upload your PNG or JPG logo, adjust the size percentage and opacity, choose the position, and click Apply Watermark.

Is my PDF uploaded to a server?

No. All watermarking happens locally in your browser using pdf-lib. Your file never leaves your device, making it safe to use with confidential or sensitive documents.

What positions are available for the watermark?

You can place the watermark diagonally across the center (most common for CONFIDENTIAL stamps), centered horizontally and vertically, in the header at the top, or in the footer at the bottom.

Can I control the watermark opacity?

Yes. Use the opacity slider to set the transparency from 5% to 100%. A value around 20–40% is typical for a subtle watermark that is readable but doesn't obscure the document content.

What image formats are supported for logo watermarks?

PNG and JPG images are supported. PNG is recommended for logos with transparent backgrounds — the transparency is preserved in the watermark.

Will the watermark appear on every page?

Yes. The watermark is applied to every page of the PDF automatically. There is no option to skip specific pages.

Is there a file size limit?

Yes. The PDF must be 50 MB or smaller. If your file is larger, try compressing it first with our PDF Compressor tool before adding the watermark.
