GOOD TO KNOW
Frequently asked questions
How do I compress an image to 100KB online?
Choose an image, use the 100 KB preset, and click Compress Image. The finished file can be previewed and downloaded immediately.
Is my image sent to PixelsToKB?
No. The browser processes the image locally, and the tool does not upload your image to our servers.
Will the output be exactly 100KB?
The tool aims for the closest practical result at or below 100KB. Exact byte counts depend on the browser's image encoder.
