About Clicknack

Clicknack is a small collection of single-purpose tools. Each one opens in your browser, needs no account and has its own page with instructions for using it. Tools that work with files, such as the EXIF tools, image tools and PDF extractor, read the files locally; the selected files are not uploaded to a server.
