Compress an image to 100KB, 500KB or a custom size
Target-size compression is useful when a website, application form or email has a file-size limit. Start with a target that is realistic for the image: photographs generally tolerate JPEG/WebP compression better than screenshots or graphics with sharp text.
JPG vs PNG vs WebP
JPG is usually a practical choice for photographs. PNG preserves sharp edges and transparency but can produce larger files. WebP can often deliver a good balance of size and quality in modern browsers. The best format depends on the image and where you need to use it.
What happens during compression?
The tool works with the image in the browser and repeatedly adjusts encoding quality and dimensions until it approaches the requested size. A precise byte-for-byte target is not always possible because image codecs work with content-dependent output sizes.
Frequently asked questions
Can I compress an image to exactly 100KB?
The tool aims for the requested target, but codec output depends on the image, format and dimensions, so the final file can be slightly above or below the target.
Does image compression change the dimensions?
The tool is designed around file size. Depending on the source and target, quality and encoding settings are adjusted; check the generated file before publishing it.
Are my images uploaded?
This tool is designed for browser-first processing, so the selected image is processed in your browser rather than stored in a permanent file library.
