Wasserzeichen
Text oder Logo aufprägen
Über dieses Tool
Add a text or image watermark to one or many photos in a single batch. Useful for protecting work-in-progress designs, marking proofs, branding social-media posts, or stamping copyright notices on photography.
Control position with a 9-point grid, fine-tune with custom offsets, and adjust opacity, scale and rotation. The watermark renders identically across every output file. Originals on disk are never touched - only downloaded copies are watermarked.

Häufig gestellte Fragen
No - your originals on disk stay untouched. Only the downloaded copies have the watermark.
Yes - alpha is preserved, so a logo with transparent background blends cleanly.
60-80% is visible without overwhelming the photo. Use lower (20-40%) for subtle stamps, 100% for clear copyright notices.
Visual watermarks can always be removed by someone with image-editing skills. They're a deterrent, not security.
Visible watermarks survive any normal copy or screenshot, since they're part of the pixel data. Invisible (steganographic) watermarks are out of scope for this tool - those need specialised software.
Yes. Upload a PNG with transparency and position it over the image. Adjust opacity and size with the sliders; the original is never modified, only the exported copy.
