Novus Examples
The current map of Novus Examples: a free library of sample and dummy files in every common type and format, made for testing converters, background removers, editors, and upload flows. Browse a format, download a genuine correctly-formed sample, and put your tool through its paces — including deliberately empty, corrupt, and oversized files for error-handling. Everything is free, needs no account, and downloads in your browser.
