How to make an image under 100 KB
The tool tries quality levels until it finds the highest one under 100 KB. If even low quality is too big, the picture is made slightly smaller and tried again, so the result always fits.
- Choose the image (JPG, PNG, WEBP or a phone photo).
- The limit is already set to 100 KB - change it if your form says otherwise.
- Press Compress images and download the result.
Good to know
100 KB is a common limit for profile photos, document uploads and email attachments. Photos from modern phones are often 3-5 MB, so this is a big reduction - the picture stays clear on screen.
Questions
Will my photo look bad at 100 KB?
On screen it usually looks almost the same. Fine details are softened slightly.
Is the result exactly the limit?
It is always at or under 100 KB (counted as 100,000 bytes, which also satisfies forms that count 1 KB as 1,024 bytes).
