About the Compress Image to KB
Many online forms set strict limits on photo size: "passport photo under 50 KB", "signature between 10 and 20 KB", "upload a CV photo under 100 KB". Hitting those numbers by trial and error is frustrating. The Compress Image to KB tool does it automatically.
Enter your target size, or tap a quick preset like 20 KB, 50 KB, 100 KB or 200 KB, and the tool searches for the highest quality that fits under your limit using a binary search on the compression level. If the image still does not fit at acceptable quality, it gradually reduces the dimensions until it does. You get the best-looking image possible for the size you need.
It is especially handy for job applications, university admissions, NADRA, passport and visa forms, bank forms and exam registrations. Everything runs locally in your browser, so your personal photos and documents stay private.

Frequently asked questions
How do I reduce photo size to 20 KB for a form?
Upload the photo, click the 20 KB preset and download the result. The tool lowers quality and, if needed, dimensions until the file is under 20 KB.
Why did my image get smaller in dimensions?
When a target is very small, reducing quality alone would make the photo look blocky, so the tool also scales it down to keep it clear.
Should I choose JPG or WEBP?
Choose JPG for forms and official websites because it is accepted everywhere. WEBP gives smaller files but is not accepted by all upload forms.
