Compress Image to 500KB

About Compress Image to 500KB

This free tool compresses an image to under 500 KB. Under 500 KB keeps a photo sharp on screen while making it light enough for websites, blogs, marketplace and real estate listings, and the many upload forms that stop at half a megabyte.

For every image, the browser searches the encoder quality step by step and keeps the highest quality that still fits under 500 KB. When lowering the quality is not enough, it scales the image down gradually until it fits, and an image that is already under 500 KB is kept as it is. A target counts 1 KB as 1,000 bytes, so the file also passes the strictest upload checks.

You can add up to 30 images at once, save them as JPG or WebP (or keep the original format), cap the width and height, and download one file or everything as a ZIP. Nothing is uploaded: the compression runs entirely in your browser, so your photos stay private. Need another size? Pick any other chip or type your own value.
