See it on real backgrounds
If the background is genuinely transparent, each colour shows through. If it’s a fake checkerboard, you’ll see grey squares on every one.

Real transparency vs a fake checkerboard
When an image is genuinely transparent, it carries a hidden fourth channel — the alpha channel — that records how see-through each pixel is. Place it on any colour and the background shows through cleanly.
The grey-and-white checkerboard you see in editors like Photoshop or Canva is just how those programs draw “nothing here” on screen. The trouble starts when an image actually has those grey squares painted into it — no alpha channel at all. It looks transparent in a preview, but drop it onto a coloured website header or a printed flyer and the grey squares appear. This is extremely common with:
- AI image generators asked for a “transparent background” that flatten the editor’s checkerboard into the picture;
- screenshots of a transparent image taken inside an editor;
- JPGs, which can never be transparent — the format has no alpha channel.
How this tool decides
We read every pixel in your browser. First we check for a real alpha channel — any fully or partly transparent pixels. If there are none, we look at the background for the tell-tale signature of a baked-in checkerboard: two near-neutral grey tones alternating in a regular grid. Then we show you the image on several solid colours so you can confirm with your own eyes.
