Why PixelSpec
Answer first
The exact pixels, ratio and safe zone are in the first thing you see. No scrolling past a template gallery.
Actually current, and labelled
Every spec carries a last-verified date and says whether the platform publishes that number itself or whether it is a widely used convention.
Private by design
The resizer uses your browser canvas. Images are never uploaded to a server, so nothing leaves your device.
Open data
A free JSON API exposes every spec so you can build the sizes into your own tools. No key needed.
