Why add a watermark to a PDF?
Watermarks are essential for protecting your intellectual property, marking documents as 'Confidential' or 'Draft', and ensuring your brand logo is visible on your work.
By permanently stamping a watermark on your PDF, you discourage unauthorized distribution and clearly identify the document's status.
Frequently Asked Questions
Can I use an image as a watermark?
Yes, you can upload your company logo or any other image to use as a transparent watermark on your PDF pages.
Will the watermark cover my text?
You can adjust the transparency (opacity) of the watermark so that it sits subtly in the background without making the document hard to read.
Is my data secure when using Dowll?
Yes, absolutely. All file transfers use advanced SSL encryption. Additionally, we never store your files—they are automatically and permanently deleted from our servers shortly after processing.
Can I use this tool on my mobile phone?
Yes! Dowll is fully optimized for mobile devices. You can process your documents easily on any iPhone, iPad, or Android device directly from your web browser without installing an app.
Are there any hidden fees or unwanted watermarks?
No. Dowll provides this service completely free of charge, with no hidden subscription fees, and we will never add our own watermark to your documents.
