Best Use Cases

Email Attachments

Many email services have attachment limits. Compressing images to under 100KB ensures fast sending and receiving.

Government & Job Portals

Online application forms often require photos under 100KB or 200KB. Use the quality slider to hit the exact limit.

Website Performance

Smaller images load faster, improving Core Web Vitals and SEO scores.

Frequently Asked Questions

How do I compress an image to exactly 100KB?

Upload your image, then adjust the quality slider downward until the output file size shows under 100KB. Converting to WebP or JPEG format also reduces size significantly.

Will compressing to 100KB ruin my image quality?

For most photos, JPEG at 60-70% quality produces files well under 100KB with acceptable visual quality. The quality loss is usually not noticeable on screens.
