Why you must watermark ID photos?

Identity theft is rising. Unscrupulous agents or data breaches can expose your clear ID photos, allowing criminals to apply for loans or credit cards in your name. Adding a specific watermark (e.g., "For Rent Application Only") invalidates the photo for any other use.

100% Private Processing

YuliusBox uses HTML5 Canvas technology to process your images directly in your browser. Your ID card photos are never uploaded to our servers. All watermarking happens locally on your device, ensuring maximum security.

Frequently Asked Questions

Are photos uploaded?

Absolutely not. You can disconnect your internet and this tool will still work perfectly. That is the best proof of privacy.

What text should I write?

Be specific. Include the purpose and date. Example: "Only for House Rental Application 2024. Invalid for other uses."
