Is this PDF watermark tool free?

Yes — completely free, no usage limits, no watermarks on the output beyond the one you add, no sign-up required.

Can I add a diagonal watermark to a PDF?

Yes. Use the rotation slider or click the 45° diagonal preset. You can set any rotation from -90° to +90°.

Can I add a logo or image as a watermark?

Yes. Switch to the Image tab, upload a PNG or JPG, and it will be stamped onto every page. PNG transparency is fully preserved, making it ideal for logos.

Can I tile the watermark across the whole page?

Yes. Switch from Single to Tiled mode to repeat the watermark in a grid pattern across every page — like a security document.

What does placing the watermark 'behind content' do?

Behind content places the watermark under the existing page text and images, giving a subtle embedded look. On top places it over everything, making it more visible and harder to remove.

Can I use {page} or {date} in my watermark text?

Yes. Type {page} to insert the current page number, {total} for total pages, or {date} to insert today's date in your watermark text.

FAQ

Frequently Asked Questions

Everything you need to know about watermarking PDFs online.

Is this tool free?

Yes — completely free with no usage limits, no sign-up, and no additional watermarks added beyond the one you configure.

Are my files uploaded to a server?

No. All processing happens entirely inside your browser. Your files never leave your device and are never sent to any server.

Can I add a diagonal watermark?

Yes. Use the rotation slider or click the 45° or -45° preset buttons. You can set any rotation angle from -90° to +90°.

Can I add my logo as a watermark?

Yes. Switch to the Image / Logo tab, upload a PNG or JPG, and use the width slider to set how large it appears on each page. PNG transparency is fully preserved.

What is tiled mode?

Tiled mode repeats the watermark in a grid pattern across the entire page — like a security document background. You can control horizontal and vertical spacing, and optionally stagger alternate rows for a more natural look.

Can I watermark multiple PDFs at once?

Yes. Enable batch mode after uploading your first PDF. Add more files to the batch drop zone — all files will use the same watermark settings. Download them all as a ZIP archive.

What does "behind content" do?

"Behind content" places the watermark under the existing page text and images, giving a subtle embedded effect. "On top of content" places it over everything, making it more prominent and harder to edit out.

Can I use {page} or {date} in my watermark?

Yes. Click the token buttons below the text input to insert {page} (current page number), {total} (total pages), or {date} (today's date in your watermark text). These are replaced dynamically on each page.
