Why We Built This?
It started with a simple frustration. In India, applying for exams like SSC, UPSC, or NEET is already stressful. The last thing a student needs is a confusing error message: "Image size must be between 20KB and 50KB."
Most existing tools were either full of ads, slow, or unsafe (uploading your personal photos to foreign servers). We decided to change that. Scan4U was born with a simple philosophy: Use modern technology (WebAssembly) to process images inside the user's browser. Fast. Safe. Private.
Engineering First
Our algorithms are calibrated to hit exact government file size limits (20KB, 50KB) without making the photo blurry.
Privacy Shield
We don't store your data. In fact, we can't. Your photos never leave your device. Once you close the tab, they are gone.
User Focused
We are a small team of developers based in India, dedicated to keeping this tool free and accessible for every student.
