Frequently Asked Questions

Helpful answers about adding watermarks to PDFs in QaviloPDF.

How do I add a watermark to a PDF document?
Upload your PDF, choose between a text watermark (with custom words, size, and color) or an image watermark (PNG/JPEG logo), adjust the opacity and rotation angle, and click "Apply Watermark & Download".
Can I use our company logo or stamp as a watermark?
Yes. Switch to "Image Logo" mode and upload any PNG or JPEG file. Transparent PNG images work especially well for company logos, stamps, and signatures.
Can I adjust watermark transparency and rotation angle?
Yes. You can customize opacity from 5% to 100% and choose rotation angles such as diagonal (-45°), horizontal (0°), reverse diagonal (+45°), or vertical (90°).
Can I apply the watermark to only specific pages?
Yes. Select "Specific pages only" and enter page ranges such as "1-5, 8" or "2-" to watermark only selected pages while leaving others unmarked.
Are my confidential documents uploaded to a server?
No. The Watermark PDF tool processes all documents 100% client-side in your web browser. Neither your PDF nor your watermark image is ever sent over the network.
