Compress Image to 100KB

About Compress Image to 100KB

This free tool compresses an image to under 100 KB. Under 100 KB is a safe size for application forms, email signatures, profile pictures, CMS uploads and web pages that need to load fast, and it leaves enough room to keep a photo detailed.

For every image, the browser searches the encoder quality step by step and keeps the highest quality that still fits under 100 KB. When lowering the quality is not enough, it scales the image down gradually until it fits, and an image that is already under 100 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.
