Frequently Asked Questions

Are my images uploaded anywhere?

No. Watermarking is done entirely in your browser using the Canvas API. Your images never leave your device.

What text should I use for a business watermark?

Use your website URL, business name, or "@handle". Keep it short — 15–20 characters maximum for clean results on most image sizes.

Can I adjust transparency?

Yes — the opacity slider controls how prominent the watermark is. 30–50% is a good balance between visible branding and not obscuring the image.

What image formats are supported?

JPG, PNG, and WEBP. Output is saved in the same format as the input.
