Frequently Asked Questions

Is it safe to upload my private photos?

Absolutely. Our tool runs 100% locally in your browser. Your photos are never uploaded to any server, ensuring complete privacy and security.

Can I process images in bulk?

Yes! You can select hundreds of images at once. Our batch processing engine handles them efficiently and lets you download everything as a ZIP file.

Does it reduce image quality?

The watermarking process is designed to preserve your image quality. Only the watermark is added, and the rest of the image remains unchanged. You can also choose "Same as Original" in export settings.
