Resize Image to 100 KB

When you need 100 KB

100 KB is a common limit for scanned documents, certificates, ID proofs and photos on job portals, scholarship and admission forms, and some bank and insurance sites. It’s also a sensible size for emailing a photo that people just need to see, not print.

Typical uses

How to do it here

1. Under 100 KB is selected in the Exams deck.
2. Drop your photo or scan.
3. Hit Repixel it ✨. The badge shows the exact bytes against 100,000. Download and upload.

Scanned documents: getting the best result

• Crop the edges. Table and background around the paper waste bytes. In Pixels mode, drag the box to the page and download; then run that file again here in KB size.
• Use good light. A dark, noisy phone scan compresses badly; daylight gives a cleaner file.
• One page per file. Portals that want 100 KB usually expect one page.
• Text first. If you have a choice, a straight-on photo of the page beats an angled one.

How the studio fits it under 100 KB

It starts at high quality and steps down only as far as needed, then, if necessary, makes the image slightly smaller in pixels while keeping the shape. You get the best-looking file under 100,000 bytes, never one over it, and a note tells you if the pixel size changed. The KB rule we use is 1 KB = 1,000 bytes, so the file also passes portals that count 1,024.

Still too big? Or too small?

If a portal also has a minimum (like 50–100 KB) and your result is a bit small, there’s nothing wrong with the file; it’s just a simple image. You can type a larger size in the optional exact pixels boxes under KB size and run again. For photos with exact pixel rules, use the exam pages such as SSC photo resize or IBPS photo resize.

Email and chat

For sharing rather than forms, 100 KB per photo is a good size: about 20 photos fit in a 2 MB email, and they still look sharp on a phone or laptop screen.
