Frequently Asked Questions
How do I compress or resize an image to 500KB?
Drop your image above. The tool binary-searches JPEG quality to land just under 500KB at the best possible quality, and only reduces the pixel dimensions if even low quality can't fit. Download the result instantly. Nothing is uploaded.
What dimensions fit in 500KB?
As a rule of thumb, a good-quality JPEG photo of about 1850×1850 pixels fits in 500KB. Simple images (documents, signatures, flat backgrounds) can be much larger; detailed photos with lots of texture need fewer pixels.
