The 100KB preset is ideal when you need both quality and compliance:
Why choose 100KB over smaller sizes?
Superior text clarity
Small print on IDs and certificates remains perfectly readable at 100KB, unlike tighter 20-50KB limits where text can become fuzzy.
Facial recognition ready
Passport and visa systems rely on clear facial features. 100KB preserves the subtle details that automated systems check for.
Print-friendly
Need a physical copy? 100KB images print clearly at 2×3 inch size, while smaller files often appear pixelated on paper.

When should I choose a 100KB photo?
Choose 100KB when the portal explicitly allows files up to 100-200KB, or when you're submitting passport photos, visa applications, university admissions, or professional profiles where image quality is important. It's the sweet spot between file size and premium quality.
Is 100KB too large for exam portals?
Most government exam portals (SSC, UPSC, Banking) require 20-50KB, so 100KB would be too large for those. Always check your specific notification. However, many international applications, visa systems, and modern university portals happily accept 100KB files.
Will a 100KB photo be clear when printed?
Yes! A well-optimized 100KB JPEG at 250-300px width prints clearly at 2×3 inch size. This makes it perfect for passport photos, visa stickers, and ID cards that need to withstand both digital verification and physical inspection.
Can I resize a 20KB photo to 100KB?
Technically yes, but it won't improve quality. You can't add detail that wasn't there originally. For best results, always start with your highest quality original photo and compress down to 100KB, rather than trying to enlarge a smaller file.
What format should I use for 100KB photos?
JPEG is almost always the best choice for photographs at 100KB. It offers excellent compression while maintaining good color and detail. PNG files at 100KB would be much smaller in dimensions, so we automatically convert to optimized JPEG for the best results.
