How to use it

Add one or more images, choose 100 KB, 200 KB, 500 KB or 1 MB, then start the queue. The tool adjusts JPG quality and, when needed, reduces dimensions to approach the target size.

Which settings to choose

Use 100-200 KB for avatars and forms, 500 KB for website images, and 1 MB for larger photos. Transparent PNG or AVIF files are exported as JPG with the selected background color.

Privacy

Your files are not uploaded to a server. Processing happens in your browser with local scripts from this site.

Limits

Very large images may take longer on phones or older laptops. If the browser runs out of memory, reduce the number of files in the queue or choose a smaller output size.
