Frequently Asked Questions

Are my images uploaded to a server?

No. All processing happens in your browser using WebAssembly. Your images never leave your device.

Can I adjust the watermark opacity?

Yes. Use the opacity slider to make the watermark more or less visible. Lower opacity is subtle; higher opacity is more prominent.

Can the watermark be removed?

The watermark is embedded into the image pixels. It cannot be easily removed, which is the purpose of watermarking for protection.

Can I watermark multiple images at once?

Yes. Upload multiple images and the same watermark text and opacity will be applied to all of them.

Can I adjust the watermark position?

The watermark is applied as a centered overlay. Adjust the opacity slider to control how visible or subtle the watermark appears.

Does the watermark survive if someone takes a screenshot?

Yes. Text watermarks are permanently embedded into the image pixels. They cannot be removed by screenshotting or basic image editing.

Does this work on mobile devices?

Yes. The tool runs entirely in your browser on any device — smartphones, tablets, and computers. No app needed.

Can someone remove the watermark from my image?

The watermark is permanently embedded into the image pixels, making it very difficult to remove cleanly. Higher opacity and tiled watermarks provide stronger protection against removal attempts.

Can I add a logo or image as a watermark?

Currently the tool supports text-based watermarks with customizable opacity and color. For logo watermarks, consider using text that matches your brand name or social media handle.

What is the best watermark position?

The tool applies watermarks as centered overlays. For maximum protection, use tiled mode which repeats the watermark across the entire image, making it much harder to crop out.

Can I watermark hundreds of photos at once?

Yes. Upload multiple images and the same watermark settings are applied to all of them. Download individually or all at once. The batch process is fast since everything runs locally in your browser.

Higher opacity (70-90%) is better for proof images or preventing unauthorized downloads

Short text like @handle or your name works better than long sentences
