Formats, explained
A guide to each image format this site reads and writes: what a file in it actually contains, where the format came from, what it does well, where it falls short, and what will open one. These pages answer the question that comes before a conversion — which format you should be using — rather than performing the conversion itself.
Every technical figure on them is read from one description of the format, so the table on a guide, the comparison on a tool page, and the head-to-head below all say the same thing. Where a page says something a table cannot, somebody wrote it.
