Image Resizer FAQ

Should I resize before compressing?

Often yes. Removing unnecessary pixels first can reduce file size more effectively than pushing quality too low.

Can I make a very small image sharp again by enlarging it?

No. Upscaling can make an image larger in dimensions, but it cannot recreate source detail that was never captured.
