How small does it need to be?

Your result is saved as a JPG, the format almost every upload form accepts. We search for the best quality that fits your limit, and only shrink the dimensions if quality alone can't get there.

100KB: profile photos and document scans

A 100KB limit is common for profile pictures, application photos and scanned certificates. Photos fit comfortably. Documents need more care, because small print turns soft if the image is shrunk too far.

Photos versus documents

A cropped portrait compresses well. A full page of text has fine edges everywhere, so it needs a bigger share of the 100KB to stay readable.

Keeping scanned text readable

Scan or photograph the page flat, in even light.
Crop away table edges and shadows before compressing.
Black-and-white or grayscale scans are usually smaller than color ones, if the form allows them.
After compressing, zoom to 100% and check the small print.

Frequently asked questions

How do I resize an image to 100KB?

Add your image, leave “Under 100KB” selected and press Compress. Download the result when it finishes.

Does resizing reduce quality?

Slightly. The tool keeps the highest quality that still fits your limit, so you only lose what is needed.

Is it private?

Yes. Processing happens in your browser and nothing is uploaded.

Will text in a scanned certificate stay readable at 100KB?

Usually, if the scan is cropped tight and the page is flat and well lit. Very small print can blur. Check at 100% zoom, and if it is soft, scan again closer to the page or ask whether 200KB is allowed.

Is 100KB enough for a passport photo?

For most online forms with a 100KB limit, yes, as long as the picture is cropped to the head and shoulders. The pixel dimensions the form asks for matter as well.
