Comprehensive Technical Guide & Reference
Upload your images, select a target portal file size (<20KB, <50KB, <100KB) or adjust the quality slider manually, and download your compressed images individually or as a batch.
11. Step-by-Step: How to Compress & Resize Images
Optimize image file sizes in three simple steps:
- •Upload Images: Drag and drop single or multiple JPG, PNG, or WebP images.
- •Choose Target Size or Format: Select portal presets (<20 KB for signatures, <50 KB for passport photos, <100 KB) or choose WebP conversion for web development.
- •Review Before & After: Inspect live file size savings percentage and visual zoom comparisons.
- •Download Single or Batch: Download optimized images individually or bundle all in a single ZIP archive.
22. Technical Explanation: Iterative Binary Search Optimization
Most recruitment portals (UPSC, SSC, IBPS, State PSC, US Visa DS-160) enforce strict file size thresholds (e.g. photo between 20KB and 50KB, signature under 20KB):
- •Binary Search Quantization: Runs an iterative binary-search loop to discover the exact highest quality parameter that satisfies your target byte cap.
- •Lossy vs Lossless WebP: WebP provides 25% to 35% smaller file sizes compared to standard JPEG at equivalent visual quality, dramatically accelerating webpage First Contentful Paint (FCP).
- •Zero Network Latency: Compression runs directly in browser CPU memory with zero upload or download wait times.
33. Preserving Aspect Ratios & Dimension Scaling
When resizing images, lock the aspect ratio to prevent distorted stretching of faces, signatures, or company logos.
