What is a .png file?
PNG (Portable Network Graphics) is a raster image format using lossless DEFLATE compression. It supports full 8- or 16-bit-per-channel truecolor, palette, and greyscale modes with an optional alpha channel, but no animation. It is the standard choice for screenshots, logos, and graphics with sharp edges or transparency.
How to use this file
Use an example PNG to test image decoders, alpha-compositing, thumbnail generators, and format converters, or to verify that a pipeline preserves transparency and color depth on round-trip.
How to use this file for testing
“PNG icon sprite (5-icon strip)” is a deterministic Novus Examples fixture for Web assets, Conversion testing. Favicons, web app manifests, service workers, robots and sitemap files, Open Graph images, and .well-known resources — for testing web tooling, crawlers, PWA installers, and asset pipelines.
Documented properties for this file: PNG sprite strip. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
Web-platform fixtures are standards-compliant samples against fictional example.com data. Test crawlers, PWA installers and manifest validators, favicon/icon pipelines, service-worker registration, or .well-known parsers against the documented structure.

- svgFavicon (scalable SVG)A scalable SVG favicon of the brand mark — the modern crisp-at-any-size icon format, for testing SVG favicon support and vector-to-raster favicon pipelines.
- atomFeed twin - Atom 1.0The same four articles as Atom 1.0: tag: ids identical to the RSS twin, RFC 3339 published and updated timestamps, escaped HTML content, and both alternate and self links. For diffing an RSS-to-Atom converter against a known answer.
- jsonFeed twin - JSON Feed 1.1The third twin: the same four articles as JSON Feed 1.1, using the 1.1 `authors` array rather than the 1.0 singular form, with ids, URLs, summaries, HTML bodies and timestamps identical to the RSS and Atom files. The reference output for an XML-to-JSON feed converter.
- rssFeed twin - RSS 2.0Four articles of a fictional publication as RSS 2.0, with a self-referential atom:link, non-permalink tag: GUIDs, RFC 822 dates and full HTML bodies in content:encoded. One of three twins carrying identical content, so a feed converter can be diffed against a known answer.
- otfOTF — CFF (Cubic) OutlinesThe same design in CFF outlines: cubic Type 2 charstrings with no glyf and no loca. The half of the pair that catches code assuming every OpenType font is TrueType-flavoured. Original typeface, free to use.
