When you need images at 100 KB
Passport photo uploads, government forms, and some messaging apps set strict limits as low as 100 KB.
Meeting these limits often requires more aggressive compression than the default preset.
Getting the best result at 100 KB
For the smallest files start with a JPG input — JPG compresses more efficiently than PNG for photographs.
If your image has solid colors or transparency, PNG may be preferable despite larger size.
Frequently Asked Questions
Can every image be compressed to 100 KB?
Very large or highly detailed images may not reach exactly 100 KB without visible quality loss. The tool will compress as far as the preset allows.
Which preset should I use for 100 KB?
Start with Max for the strongest compression. If quality is too low, try Balanced and check if the result meets your limit.
Is this tool really free?
Yes. There are no charges, no hidden fees, and no account required.
