FAQ
How small can it make an image?
The tool lowers quality and scales the image until it fits under your KB target. Very small targets may reduce resolution, but you always get the smallest version that works.
Can it resize for a website upload limit?
Yes — enter your upload limit in KB and it produces a compliant image, ideal for forms that cap file size.
Is the result good quality?
The tool keeps the highest quality that still fits the target. For most uses, a 20-100KB JPEG looks sharp on screen.
