Frequently Asked Questions

Why do government and exam portals require photos under 20 KB?

Public admission portals and visa systems enforce strict file size caps (often 20 KB) to optimize database storage and ensure rapid form processing. BatchPixel guarantees your upload passes without rejection.

Will my signature or photo remain clear at 20 KB?

Yes. BatchPixel first explores the highest possible JPEG quality at original dimensions, only applying gradual 10% scaling if necessary so text and signature strokes stay crisp.

Is it safe to upload sensitive IDs and passports?

BatchPixel executes 100% locally on your machine. Your sensitive identification images are never uploaded over the internet or stored on third-party servers.
