PNG-supporting Image Viewers
Image Viewers with PNG Support
One of the biggest categories of PNG-supporting applications is image viewers; virtually every major
operating system is represented. Note that PNG image editors can often be used as viewers, too; they
just tend to be slower and may not display as nicely on 256-color systems. And there's considerable
overlap between this page and the image-conversion page, since many viewers can save to different
formats. A few of the viewers here even have minimal editing functions like cropping, color balance,
etc. Follow the links for details. Ye have been warned...
As with the other applications pages, links to home WWW sites or to downloadable versions are
provided where known, but if a link is broken, check the location and see if an updated version is
available (and please tell Greg!). Relevant operating systems are printed in (parenthesized italics).
