Frequently Asked Questions
How does resizing by Centimeters (CM) or Millimeters (MM) work?
Our engine calculates exact pixel values using the standard formula (Pixels = Millimeters / 25.4 * DPI). When you enter 3.5 x 4.5 cm at 300 DPI, it converts the canvas to 413 x 531 px and embeds a verified 300 DPI JFIF header.
What is the difference between Proportional, Force Stretch, and Pad to Canvas?
Proportional maintains your photo's original ratio. Force Stretch stretches the image to fit exact dimensions. Pad to Canvas fits your image inside a target box (e.g., 300x100 px signature) without distortion by centering it over a solid white or transparent margin.
Does this tool support official exam presets like SSC, UPSC, and PAN?
Yes! Clicking our 1-Click Presets automatically loads standard requirements for SSC Photo (3.5x4.5 cm), SSC Signature (4x2 cm), and NSDL PAN Card Photo (213x213 px).
Can I compress the file size (KB) while resizing?
Yes. Enable the 'Target KB Guard' to ensure the resized image also stays strictly below your required file weight (e.g., <= 50 KB or <= 20 KB).
Is my data processed locally?
100% locally. All file decoding, resizing, header injections, and ZIP compressions run directly in your browser's RAM without uploading images to any external server.
