Preserving Critical Numbers & Official Seals at 100 KB
When compressing certificates and declarations to under 100 KB, automated algorithms often blur fine 8-point numerical digits or official rubber stamps. Follow these 3 practical rules:
1. Use Plain Unruled Paper
Horizontal blue or grey notebook lines create high-frequency edge data that wastes up to 25 KB of compression budget. Writing declarations on blank A4 paper keeps the file compact and readable.
2. Grayscale Chroma Savings
For black-and-white documents, converting to grayscale strips redundant color chrominance channels (Cb/Cr), shedding 20% to 30% file size without degrading letterform sharpness.
3. Eliminate Phone Shadows
Uneven lighting forces JPEG encoders to create gradient quantization steps across shadowed areas. Photograph documents under balanced daylight to ensure pure white backgrounds.
दस्तावेज़ सलाह: हस्तलिखित घोषणा हमेशा सादे सफेद कागज़ पर काले पेन से लिखें। लाइन वाले कागज़ का उपयोग न करें। 100 KB में कंप्रेस करने पर मार्कशीट के रोल नंबर और मुहर पूरी तरह साफ़ दिखाई देते हैं।
