Fixpicture, which seems to be affiliated with the great image viewer XNView, is such a online script that lets you easily convert and resize images in a matter of seconds. The service supports nearly 400 image formats, provides a flash (not working at the time of writing) and html version and translations for several languages.

The size restriction for images is three megabytes which should be enough under most circumstances. I would not be able to download high quality images made with my digital camera Casio Exilim EX-Z700 with 7.2 Megapixel which creates images that have a size of more than four Megabyte.

It is possible to use some of the default resize options or define a custom size. The maximum is 1000 pixels which is not that much either but enough for web publishers for instance.

The only mandatory option is the output quality which can be selected to be good, better or best and the output format with the choice between jpg, png, tiff, pdf, bmp and gif.
