Frequently asked questions
Can I make the file under 1024KB?
Yes, the tool works toward 1024KB and downloads a file under that limit when the browser can produce one. If the result is still too large, try WebP or a slightly larger target.
Is this safe for private photos?

Can I choose JPG output?
Yes. JPG is available as an output format, along with WebP and PNG.
