Why In-Browser Processing is Essential for Sensitive Photos & IDs

🔒 Zero Cloud Uploads

Signatures, Aadhaar IDs, and passport photos are sensitive personal biometric assets. PixelKit processes all operations locally in browser RAM.

⚡ Sub-Second Quantization

Powered by WebAssembly and Canvas binary-search encoding, resizing and compressing takes under 200ms with zero server latency.

🎯 Portal Pass Guarantee

Dimensions, aspect ratios, and KB file limits are locked directly to the official government guidelines for immediate intake clearance.

Frequently asked questions

Why was my photo rejected in the previous RRB application?

The most common reasons for RRB photo rejections are selfies, wearing sunglasses or caps, patterned backgrounds, and file sizes outside the strict 20KB–50KB bracket.
