The Problem

Government Portals are Brittle

Have you ever tried to upload a photo for a US Visa, NTA Registration, or Passport Renewal, only to see "Upload Failed"? Government portals are notoriously brittle. They crash if your photo has hidden metadata (EXIF), if the resolution is 1% too high, or if the file size is 201KB instead of 200KB. Users get stuck for hours trying to "guess" the right format.

Challenge

The Solution

A Compliance Engine, Not Just a Compressor

I engineered Under 200KB—a specialized utility designed to bypass these strict digital gatekeepers. It automatically strips hidden metadata, forces compliance by intelligently resizing images without blurring faces, and operates entirely in-browser for privacy. No data leaves the user's phone.

Process

Engineering for the Real World

Built for environments where bandwidth is expensive. The entire app respects the "37KB Rule" - smaller than a single low-quality JPEG, loading instantly on 3G networks. It uses the Canvas API for client-side processing, ensuring 100/100 Google Lighthouse performance.

Phase 1
