Drop a live image resizer into any blog post or page with one iframe. It comes preloaded to the size you choose, runs entirely in the visitor's browser, and carries a small Powered by PixelSpec link.
The widget is a normal iframe pointing at a page on PixelSpec. Nothing is uploaded: the visitor's image is processed with the browser canvas, exactly like the full site. Set the height to taste; 560 pixels fits the tool comfortably.
Good places to use it
A blog post about a specific platform size, next to the spec.
A social media resource page or client onboarding guide.
An internal wiki where a team resizes assets often.
Prefer raw data? The JSON API exposes every spec, and the cheat sheet lists them all on one page.
