Why Online Portals Reject Uploaded Images

Every government exam and service portal (SSC, UPSC, NSDL PAN, IBPS, State PSCs) enforces strict mathematical limits on uploaded photos and signatures. Submitting a file that is even 1 KB above the maximum threshold or lacking the required aspect ratio results in immediate form rejection.

Exact Target KB Guarantee

Type your desired KB limit (e.g. 20 KB, 50 KB), and our smart iterative algorithm hits the exact file size target automatically.

Multi-Unit Dimensions Support

Easily switch between Pixels (px), Centimeters (cm), Millimeters (mm), or Inches (in) with automatic aspect ratio preservation.

300 DPI Metadata Injection

Injects official 300 DPI print headers required for NSDL/UTI PAN card forms (213x213 px) and state recruitment portals.

Everything you need to know about target KB image compression.

How do I compress an image to exact 20 KB or 50 KB without blur?

Upload your photo, select the "Target KB" mode, and type 20 or 50. The tool runs an iterative binary-search compression algorithm in your browser that preserves facial details and sharp edges while hitting the exact target size.

How to resize photo for PAN Card (213x213 pixels at 300 DPI)?

Select the "Dimensions" mode, enter 213 in width and 213 in height with unit set to "Pixels", and choose 300 DPI. Under file size, set under 30 KB. Click Resize & Download to get an instantly accepted PAN card photo.

Does resizing images locally protect my personal documents?

Yes. eMitraTool performs all cropping, scaling, and re-compression directly on your computer or phone using HTML5 Canvas. Your sensitive certificates and photographs never leave your device.

Can I resize signatures and thumb impressions with this tool?

Yes. Select signature presets (such as 10 KB to 20 KB or 3.5 x 1.5 cm). The tool optimizes monochrome and high-contrast lines so signature strokes remain crisp and legible.
