FAQ

Compress JPEG: questions and answers

How do I reduce a JPG's file size?

Add the JPG on this page and choose a KB limit. The tool lowers the JPEG quality only as far as needed to fit, keeping the width and height when it can.

Does compressing a JPEG lose quality?

A little, but at normal limits it is hard to see on screen. The tool always picks the highest quality that fits your limit. Make the image smaller in pixels first if you need a very small file.

Can I compress PNG or iPhone photos too?

Yes. PNG, WebP and HEIC photos are opened and saved as JPG, which is usually far smaller. Choose PNG or WebP under Format if you need to keep that type.

Is my photo uploaded to a server?

No. The image is resized inside your web browser on your own device, so 0 bytes are uploaded and nothing is stored. It even works offline once the page has loaded.
