Can I compress PNG images using this tool?

Yes. PNG images are accepted and may be converted to JPEG when needed to reach a small target size.

Why does my photo look blurry after compression?

Very small targets reduce image detail; start with a sharp source and avoid repeatedly compressing the same file.

Is there a limit to how many images I can compress?

No site limit is imposed because compression runs locally in the browser.

The Ultimate Guide to Photo and Signature Compression for Indian Examinations

Image processing logic, portal specifications, and step-by-step guidance to avoid form rejections.

1. How Client-Side Browser Compression Works

Unlike conventional online compressors that upload your private photos to remote servers, our tool processes images client-side using the HTML5 Canvas API. The image is rendered and rescaled in local memory, keeping your documents secure and confidential.

2. Official Exam Portal Photo & Signature Criteria

Exam Agency	Document	Allowed Size	Dimensions

3. Important Rules to Avoid Rejections

Face Coverage: Ensure 70% to 80% face coverage with a plain white or light-colored background.
No Eyewear / Caps: Spectacles and caps cause flash reflections and lead to automatic photo rejections.
Signature Ink: Always sign using a black ink pen on clean white unruled paper for high contrast scanning.
