Novus Examples Real example files for testing, documented and free to use.
Sample PDFs, images, audio, video, data files and archives. 8,584 of them across 27 categories, built deliberately for testing software that has to open them. Every file has a page listing exactly what is inside, so you know what a correct result looks like.
Safe to use anywhere
Every file is generated by a deterministic script rather than collected from the web, so it ships with an exact spec sheet and no copyright exposure.
You know what is inside
Each file has its own page listing precise properties (noise sigma, silence timestamps, form fields, encodings, seeds) instead of being dumped in a folder.
Matched before-and-after pairs
352 matched pairs: clean ↔ noisy, colour ↔ greyscale, source ↔ scanned. Testing a change needs both sides, and a file on its own cannot give you that.
