Why Add a Watermark to Your PDF?
Protect Your Intellectual Property โ Watermarks deter unauthorized use of your documents. Adding "CONFIDENTIAL" or "DRAFT" across your PDF makes it clear the document is not final or should not be shared.
Brand Your Documents โ Adding your company logo as a watermark is a subtle way to promote your brand every time someone views your PDF.
Track Document Versions โ Label different versions with unique watermarks (e.g., "Version 2.0" or "Draft 3") to easily identify document stages.
Mark Sample or Preview Copies โ If you're sharing a preview before payment, a watermark ensures the recipient can't use the preview as the final version.
Frequently Asked Questions
Will the watermark affect my PDF quality?
No. The watermark is added as an overlay and does not modify the original content. Your PDF's quality remains completely unchanged.
Can I remove a watermark after adding it?
Once a watermark is applied and the PDF is saved, it cannot be easily removed. We recommend keeping a backup of the original file before adding watermarks.
Is there a file size limit?
PDF files up to 100MB are supported. For image watermarks, the image should be under 20MB. Supported formats: PNG, JPG, GIF, WEBP.
What's the difference between text and image watermarks?
Text watermarks use custom words (like "CONFIDENTIAL" or "DRAFT") rendered in your chosen font and color. Image watermarks let you upload a logo or graphic to overlay on your PDF pages.
Can I watermark multiple PDFs at once?
Currently, we process one file at a time. Batch watermarking is on our roadmap.
Are my files secure?
Yes. Uploaded files are processed securely and automatically deleted from our servers within 60 minutes. We do not store, share, or access your documents.
