Frequently Asked Questions

Yes, this tool is completely free with no limits on usage. All processing happens in your browser, so there are no server costs or subscriptions. You can watermark as many images as you need.

Absolutely. Your images never leave your device. All watermark processing is done entirely in your browser using the HTML5 Canvas API. No images are uploaded, stored, or transmitted to any server.

The tool supports four watermark styles: Text Watermark (custom text at any position), Image Logo Watermark (overlay your logo), Diagonal Watermark (text stretched across the full image diagonal), and Tiled/Repeating Pattern (watermark repeated across the entire image).

Yes, the opacity slider lets you set transparency from 1% to 100%. A lower opacity creates a subtle watermark that does not distract from the image, while higher opacity makes it more prominent and visible.

You can upload up to 30 images at once. The same watermark settings are applied to all images. A progress bar shows the processing status for each image, and you can download them individually or all at once.

All watermarked images are downloaded as PNG files, which support full transparency and lossless quality. This ensures your watermark looks crisp and professional regardless of the original image format.

Yes, the tool is fully responsive and works on smartphones and tablets. The interface adapts to smaller screens with full-width controls and a scrollable preview. You can watermark images directly from your phone's camera roll or file manager.
