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.
