Images that look different
in different apps.

Every file here is a normal, standard image. They look different because apps handle optional features differently: transparency, colour profiles, rotation tags, CMYK, animation, or how they shrink pictures.

How it works

  1. 1

    Pick a trick

    Seventeen, from hidden-under-transparency to size-reveal.

  2. 2

    Make the file

    Previews show how each kind of app should show it.

  3. 3

    Test it and record it

    A results board keeps what worked where, and when.

Ground rules

  • Valid files only: nothing malformed or meant to crash anything.
  • The lab never uploads your pictures or contacts other sites; only results you choose to record are saved here.
  • Just for fun: don't use it to mislead people or get around a site's rules.

Questions

Is it free?

Yes. It runs in your browser, so your pictures are never uploaded.

Will it work on my site?

It depends on how that site processes images, which changes over time. That's what the results board is for.
