Frequently Asked Questions

Are my images uploaded to your servers?
No. All watermarking happens entirely in your browser using the HTML5 Canvas API. We never see, store, or transmit your images. Your files stay on your device throughout the entire process.
Can I choose where the watermark is placed?
Currently, watermarks are automatically placed in the bottom-right corner, which is the most standard and visually appealing position for copyright and branding watermarks.
What image formats are supported?
You can watermark JPG, JPEG, PNG, and WebP images. The watermarked output is saved as a PNG file to ensure the text overlay is rendered with perfect quality.
Can I watermark multiple images at once?
Yes. You can upload multiple images and apply the same watermark text to each one. Each watermarked image is available for individual download.
Will the watermark affect the original image quality?
The original image quality is fully preserved. The watermark text is rendered on top of the image data without altering the underlying pixels — only the watermark layer is added.
What is the best watermark text to use?
For copyright protection, use your name or © YourName YEAR. For branding, use your website domain or company name. For document marking, use CONFIDENTIAL, DRAFT, or SAMPLE — whatever best communicates the status of the image.
