Compress Image to KB (Under 100 KB)

Many application, exam, job and visa portals only accept photos up to a certain size, such as "max 100 KB". Pick the target size and Fotudio converts your image to JPG and finds the highest quality that still fits. Pixel dimensions are reduced only when the limit cannot be reached otherwise.

Your images stay on your device. Processing happens entirely in your browser.

Frequently asked questions

How do I get a photo under 100 KB?

Select 100 KB and start. The tool tries different JPG quality levels and keeps the best one that stays under 100 KB. The result shows the new file size and pixel dimensions.

Will the pixel dimensions change?

Only if necessary. Quality is lowered first; if the photo is still too large at the lowest sensible quality, the width and height are reduced step by step until it fits.

Why is the result a JPG?

JPG gives the smallest files for photos and is accepted by almost every upload form. PNG, WebP and HEIC images are converted to JPG automatically, with transparent areas filled in white.

The form also asks for specific pixel dimensions. What should I do?

First resize or crop the photo to the required dimensions with our resize or passport photo tools, then compress the result here to the required KB.

Are my photos uploaded?

No. Everything happens in your browser, so your photos never leave your device. That matters for ID and document photos.
