Frequently Asked Questions
Can watermarks be removed?
Our tool embeds watermarks permanently into images. While tech-savvy users might remove simple watermarks, positioning strategically and using appropriate opacity makes removal difficult.
What opacity should I use?
For visibility: 80-100%. For subtle protection: 30-50%. For portfolio preview: 20-40%. Balance protection with viewer experience.
Should I use text or logo watermarks?
Logos look more professional and brand-focused. Text watermarks are simpler and work without logo files. Many use both for maximum protection.
Is this tool really free?
100% free with unlimited use. We don't add our watermarks to your watermarked images. No signup, no hidden fees.
Where should I position watermarks?
Bottom corners for minimal distraction. Center for maximum protection. Tiled for comprehensive coverage. Avoid important focal points.
Are my images safe?
Completely safe! All watermarking happens in your browser. Images never uploaded to our servers. Total privacy guaranteed.
