What is Compress Image to 100KB?

Compress Image to 100KB is an online tool crafted for university admissions, KYC (Know Your Customer) identity verification, recruitment portals, and job applications that require image uploads strictly capped at 100KB.

100KB provides the sweet spot between high resolution and lightweight file transfer. However, modern smartphone cameras capture photos between 3MB and 12MB. Our smart compression algorithm reduces file size by up to 98% while keeping text, stamps, signatures, and photographic portraits crisp and legible.
