When and How to Target 100KB
When an online submission platform or document verification system permits file sizes up to 100 KB, targeting this higher ceiling allows you to retain superior visual fidelity. You can keep higher pixel dimensions and richer color transitions while staying safely below the maximum file limit.

A 100 KB ceiling easily accommodates larger resolutions like 600 × 800 px, preserving fine hair, garment textures, and facial contours.
Size an identification card badge photo under 100 KB. Or trim a scanned physical photograph to remove uneven white borders while keeping it under 100 KB.
Choose between standard ratios like 3:4, 4:5, square 1:1, or customized dimensions in centimetres or millimetres at 300 DPI.
All image encoding happens directly in your browser on your device. Your sensitive identification images are never transmitted or stored remotely.
