Launch notes and practical guidance for Novus Examples: 5,075 files across 27 categories and 288 extensions, generated by deterministic scripts rather than collected, each with an exact spec sheet and often a clean-to-noisy twin, made for testing converters, background removers, editors, parsers, and upload flows. Plus 840 visual templates and OBS-compatible scene collections for the broadcast set. Browser-first, free, and no account required.

About the Novus Examples thread
Every developer who has tested an upload flow has been through the same twenty minutes: hunting for a CMYK TIFF, or a corrupt ZIP, or a video with an unusual codec, so they can find out what breaks. Novus Examples exists to end that hunt: 5,075 generated test files across 27 categories and 288 extensions, each with an exact spec sheet describing what it contains and why.
The files are generated by deterministic scripts rather than collected, which matters more than it sounds: it means the properties are known and stated, and it means clean-and-noisy twins of the same file exist so you can isolate exactly which property broke your parser. On top of the fixtures sit 840 visual templates and fifty-two live pages built specifically as targets for accessibility, scraper, and automation testing.
What this topic covers
- The 5,075-file library: what each of the 27 categories holds and how the spec sheets read
- Test files designed to break things on purpose: malformed, oversized, and adversarial fixtures
- Clean-to-noisy twins for isolating exactly which property a parser choked on
- Video fixtures (402 of them), codec coverage, caption tracks, and ground truths
- fifty-two live automation and accessibility targets, plus OBS-compatible scene collections
Who it's for
Developers and QA engineers testing upload, parsing, and conversion paths; accessibility auditors; and anyone who needs a specific file format right now.

Generated, not collected: what a test file’s provenance decides

The test files that break your app, on purpose
The most useful test files are the ones built to fail on purpose, and generating them to spec is what makes those failures reproducible.

Novus Examples: free sample and dummy files for every format
Why the test files you reach for at the worst possible moment deserve a real home, organized by format and edge case instead of scattered across old downloads.
