The tool lowers the quality step by step until the file fits, and only scales the image down when quality alone is not enough.
The real-world form requirement: an exact pixel size that also has to stay under a file size limit.

How to Resize an Image to 100 KB
A 100 KB limit almost always comes from a document or certificate upload. 100 KB is generous enough for a readable scan of a certificate, ID card or diploma, which is why so many portals settle on it. The form checks the file size and nothing else, so the job is to give away as little sharpness as possible while still landing under 100 KB.
Why 100 KB?
For text documents, resolution matters more than colour depth - keep the pixel dimensions high and let the quality drop, so the text stays legible. This tool encodes your photo at several quality levels and keeps the best one that still fits 100 KB, instead of applying a fixed compression setting and hoping for the best.
Resizing to 100 KB Step by Step
Drop the photo into the upload area, check that the target is set to 100 KB and click resize. You will see the original size next to the result, so you can confirm it fits before downloading. Everything happens in your browser - the photo is never uploaded, which matters when it is an ID document or a passport picture.
