How do I add a watermark to a PDF for free?
Upload your PDF, choose text or image watermark, customize its appearance and position, then download. No cost, no limits.
Can I add my company logo as a watermark?
Yes! Upload your logo image (PNG or JPG), adjust its size and opacity, position it where you want, and apply to your PDF.
How do I add diagonal "CONFIDENTIAL" text?
Select text watermark, type "CONFIDENTIAL", choose the diagonal rotation preset (45°), adjust opacity, and apply across all pages.
Can I control watermark transparency?
Yes. Use the opacity slider to make your watermark subtle (10-30%) or prominent (70-100%). Perfect for backgrounds that don't obscure text.
Can I watermark only specific pages?
Absolutely. Choose which pages get the watermark - all pages, odd/even only, or custom ranges like pages 1-10.
Will the watermark affect PDF text?
The watermark is added as a layer. Text underneath remains selectable and searchable. Adjust opacity so it doesn't interfere with readability.
Can I add multiple watermarks?
Apply one watermark per session. For multiple watermarks, download the result and re-upload to add another watermark.
Is watermarking permanent?
Yes, watermarks are embedded in the PDF. They can't be easily removed without specialized tools or the original file.
Is adding watermarks free?
Yes. Wow1 is 100% free with no limits on file size, pages, or usage. No registration required.
Are my files uploaded when adding watermarks?
