ISH to WEBPLL Conversion: FAQ

What are ISH files?

ISH is an archaic bitmap image format associated with Image Speeder and Image System — two image processing programs which have been long discontinued. In case you found such a file on your hard-drive or were sent one, it is probably very old and will be difficult to open. For best results, we recommend converting it to a more widely used format.

What are WEBPLL files?

WebPLL is the lossless version of WebP, an image format released by Google in 2010 with the declared objective of improving browsing times. WebPLL images are aimed to offer the same quality as other standard image formats used online, such as JPEG and PNG, but in a smaller size. Although received with enthusiasm, the two Google formats are still not compatible with some browsers and viewers, and have features that need to be developed in the future for wider accessibility.
