Why Use a 100% Local Browser ID Photo Maker & Exact KB Sizer?

Whether you are applying for a US/Japan Visa (2×2 inch / 600×600px), civil service exams, professional certifications, or university admissions, online application portals enforce strict pixel dimensions, background colors, and exact kilobyte (KB) file size windows.

  • Edge Flood-Fill Chroma Matting: Replaces light indoor walls with Official Blue, Pure White, Official Red, or Executive Grey gradients without erasing facial highlights or white shirt collars.
  • Exact KB Target Sizer (e.g. 15–30 KB): Binary-searches JPEG encoding quality and applies lossless byte padding so your photo passes automated portal validators on the first try.
  • 4×6" (1800×1200px) Multi-Up Print Sheet: Automatically tiles your ID photos onto a 300 DPI 6-inch photo canvas complete with precision scissor crop marks.

Frequently Asked Questions (FAQ)

Q1 How does the Exact KB File Size Controller work for exam and visa portals?
Many government exam and visa portals reject ID photos that are either above 30 KB or below 15 KB. Our tool runs an 8-step binary search over JPEG quantization quality to get as close to your maximum KB limit as possible, and injects a benign JPEG comment segment if needed to guarantee your file never falls below the minimum KB threshold.
Q2 Are my biometric portrait photos uploaded to any cloud server?
No. Every step—from edge-flood background replacement and formal suit overlay to 6-inch print sheet composition—runs 100% locally in your browser via HTML5 Canvas. Your portrait never leaves your device.
Q3 How can I print 8 ID photos for $0.15 using the 6-Inch Print Sheet?
Instead of paying $5–$15 for "Passport/ID Photo Printing" at a pharmacy or studio, download the generated 4×6 inch (1800×1200px @ 300 DPI) multi-up sheet with crop marks and print it as a single standard 4×6" photo.
