Every guideline on this platform is verified against live application portal validation criteria so candidates never have to guess whether their uploaded assets comply.
Key Technical Concepts Demystified
Aspect Ratio & Pixels
Aspect ratio is the proportional relationship between image width and height. For instance, SSC requires 3.5cm x 4.5cm (a 7:9 ratio). Forcing a square 1:1 image into this frame without proportional cropping causes facial stretching.
Target KB vs. Resolution
Compressing a file to under 50KB should never mean reducing image resolution to a blurry smudge. Modern bicubic downsampling preserves crisp facial edges while eliminating wasteful color metadata.
Vector Text vs. Raster Images
PDF files generated from word processors contain scalable vector text that can be parsed by ATS bots. In contrast, scanned paper produces raster pixel grids that require OCR to become searchable.
