Frequently asked questions

Why do I need an image under 500 KB?

500 KB is a common upload cap on forums, content management systems and job portals that accept full-size photographs.

Can any image be compressed to 500 KB?

Yes. Half a megabyte is enough for a full-resolution photograph at good quality, so this target rarely costs anything visible.

What will the result actually look like at 500 KB?

A full-resolution photograph at good quality. At half a megabyte the compression is rarely something you can point to on screen.

How does it hit the target?

It repeatedly re-encodes the image, adjusting quality by binary search until it finds the highest setting that still fits. If quality alone cannot get there, it progressively reduces the pixel dimensions as well. The whole search runs on your device, typically in under a second.

Which format gives the smallest file?

JPG for photographs, which is what forums and job portals expect. WebP if the destination is a site you control.
