Prepare an image for a 300KB file-size limit
Many application systems impose a maximum file size without specifying exact image dimensions. This page preloads 300KB as the maximum and lets SizeFix balance quality and size locally in your browser.
If the image cannot reach the target through quality adjustment alone, reducing dimensions can help. The result panel shows the final size before you save it.
300KB image FAQs
Can the final image be less than 300KB?
Yes. The target is a maximum, so a smaller valid file is acceptable.
Can I keep the original dimensions?
Leave width and height blank. SizeFix will first try to meet the size target without an explicit resize.
