How do I compress an image to exactly under 100KB?

Upload your image and adjust the quality slider. Start at 40% and check the output size. Decrease quality if still over 100KB, or increase if you have room for better quality.

Will my image look blurry at 100KB?

At 100KB, some quality loss is expected, especially for large or detailed images. For passport photos and ID images (typically small), 100KB produces perfectly acceptable results.

What types of uploads need images under 100KB?

Common uses include government ID uploads, passport photo submissions, exam registration portals, visa applications, and online forms with strict file size limits.

Can I resize the image too to help reach 100KB?

Yes. Reducing image dimensions helps reach 100KB more easily. Use our resize tool first to reduce dimensions, then compress to get under 100KB with better visual quality.
