Compress an image to 50 KB
50 KB is about as tight as upload limits get. Zelio lowers the quality first and shrinks the pixel size only when it has to, until the JPG fits.

FAQ
Is the result always under 50 KB?
Yes. Every file you download is 50 KB or smaller, or it's marked as failed.
Why did the pixel size shrink?
Phone photos are often 3000 pixels wide or more. At 50 KB quality alone isn't enough, so the image is scaled down as well.
Does it work on my phone?
Yes. Open this page in your phone's browser, pick a photo and download the result. Nothing to install.
My photo is already under 50 KB.
A JPG that already fits is returned unchanged.
