Frequently Asked Questions (FAQ)
Why should I add a watermark to my ID or passport copy?
Adding a purpose-specific watermark (such as 'FOR VERIFICATION ONLY') and date to your ID copy prevents identity theft and unauthorized reuse for fraudulent loans, unauthorized registrations, or account openings.
Is my ID photo uploaded to your server?
No, absolutely not. All image rendering, text watermarking, and mosaic operations are executed client-side inside your browser via HTML5 Canvas. Your photos never leave your device.
What is the best watermark text for official documents?
We recommend including the recipient's name and intended purpose, such as 'FOR [COMPANY NAME] VERIFICATION ONLY - [DATE] - NOT FOR OTHER USE'. Using diagonal tiling ensures the watermark covers the entire document without obstructing critical readable details.
Can I hide sensitive information like my national ID number?
Yes! Use our built-in 'Mosaic / Privacy Mask' feature to place a resizable blur or solid black box over sensitive numbers, barcodes, or signatures before sharing your document.
