Compress Image File Size

Reduce image file size to meet strict upload limits on Indian government exam forms and job portals. Target exact thresholds such as 20 KB, 50 KB, 100 KB, or 200 KB with intelligent iterative compression that preserves visual sharpness.

Key Recommendations & Best Practices

  • Target KB Presets for Indian Forms: One-click presets calibrated for UPSC (300 KB), SSC (50 KB), NTA (200 KB), and IBPS (50 KB).
  • Iterative Quality Tuning: Binary search compression algorithm finds the highest possible visual quality that fits below your target KB.
  • Live File Size Meter: See your exact before-and-after file sizes in Kilobytes with real-time percentage reduction readout.
  • Side-by-Side Visual Inspection: Inspect the compressed preview before downloading to ensure signatures and text remain completely legible.

Binary Search Compression Algorithm

Executes iterative binary search across DCT (Discrete Cosine Transform) quantization tables (quality range 0.05 to 0.95).

Dynamically downsamples pixel dimensions if 100% quality at original resolution cannot physically achieve the requested target KB.

Preserves high-frequency edge detail critical for signatures, handwritten text, and official stamps.

Runs 100% in client-side WebAssembly / Canvas memory with zero network latency.

Strict Indian Recruitment Portal File Size Limits

Almost every major Indian portal (SSC CGL/CHSL, UPSC CSE, NTA NEET/JEE, SBI/IBPS PO, Railway RRB) automatically rejects uploaded files that exceed narrow size windows (e.g., photo must be strictly between 20 KB and 50 KB; signature between 10 KB and 20 KB).

Key Recommendations & Best Practices

  • For SSC forms, select the "50 KB" preset for candidate photo and "20 KB" preset for signature.
  • For NTA NEET/JEE forms, select the "200 KB" preset for passport photo and postcard photo.
  • Never use screenshot tools to compress photos as they blur facial features and cause exam hall admit card verification issues.

Troubleshooting & Fixes

Common Errors & Troubleshooting Guide

Quick solutions to common upload errors, portal rejections, and browser canvas issues

Why this happens:

Standard compression indiscriminately discards image data, blurring edges and text.

Recommended Fix:

We use intelligent luminance quantization: it preserves high-contrast edges (text & signatures) while compressing flat background areas.
