FAQ

How do I add a text or logo watermark online?

Simply upload your image, select 'Text Watermark' to enter your copyright info, or 'Image Watermark' to upload your logo. You can preview the watermark effect in real time, adjust it until it looks perfect, and export with one click to quickly complete copyright protection.

How can I prevent image theft? Does it support full-screen watermark tiling?

Absolutely. To effectively prevent image theft, we offer a 'Full-Screen Tile' mode. You can spread text or logo like tiles across the entire image and adjust transparency so it doesn't affect viewing while maximizing the anti-theft deterrent effect.

Can I customize the watermark position and transparency?

Of course. The tool supports precise 3x3 grid positioning (like top-left, bottom-right, center, etc.) and also allows free dragging. Plus, you can fine-tune watermark transparency, rotation angle, font size and color to ensure it blends perfectly with your image.

Can I save frequently used logo watermarks?

Yes. To make e-commerce operations and brand promotion easier, you can save your common logos or signatures to the material library. Next time, just call them directly without re-uploading, greatly boosting your bulk image processing efficiency.

Will image quality be reduced after adding a watermark?

No. Our processing runs locally in your browser at ultra-fast speed. Adding a watermark only overlays an image layer, so the original image's clarity, colors and details are fully preserved, exporting high-quality images with zero compression loss.
