Frequently Asked Questions

Can I control watermark transparency and make it semi-transparent?

Yes, you can adjust opacity from 0% (invisible) to 100% (fully opaque). 30-50% opacity works well for visible but non-intrusive watermarks.

Can I position the watermark in different locations like corners or center?

Yes, you can place watermarks in all four corners, center, or any custom position. You can also tile watermarks across the entire page for maximum protection.

Will adding a watermark affect text selection or searchability?

No, original text remains fully selectable and searchable beneath watermarks. Watermarks are added as overlay layers without modifying the underlying content.

Can I use my logo or image as a watermark instead of text?

Yes, you can upload PNG, JPG, or WebP images as watermarks. PNG format with transparency works best for logo watermarks that blend naturally with the document.
