About Pixel360

Pixel360 is a free collection of calculators and converters for web designers, front-end developers, photographers and anyone who works with screens, images and color. No sign-up, no downloads, no tracking of what you type.

Who builds it

Pixel360 is built by Sumair Roudani, founder and CEO of the software company Avancera Solution and a PMP-certified project manager who has led web and app projects for more than 13 years. These are the tools the team kept needing on real client work. .

How we build and check the tools

  • Every tool runs entirely in your browser: fast, free and private.
  • Each page shows the formula it uses, so you can check the maths yourself.
  • We test results against worked examples and published references before a tool goes live, and review pages regularly.
