Frequently Asked Questions

What is the aspect ratio of a 3.5 × 4.5 cm passport photo?

The aspect ratio is 7:9. When measured in pixels at 300 DPI, it converts precisely to 413 pixels wide by 531 pixels tall, which satisfies Indian Passport Seva, OCI, and state service commissions.

How can I resize a signature without stretching or distorting it?

Uncheck "Lock aspect ratio" if your portal requires exact non-proportional dimensions (such as 140 × 60 px). Our high-resolution bilinear interpolation engine ensures smooth strokes without jagged pixelation.

Does this tool upload my photo to any server?

No. All resizing is computed locally in your web browser using HTML5 Canvas APIs. Your images never leave your computer or phone.
