📝 About Transparent BG Checker
Transparent BG Checker lets you see at a glance whether a PNG or WebP image really has a transparent background. Drop in an image and it’s shown over a grey-and-white checkerboard, the same pattern used by image editors. If you can see the checkerboard around your artwork, those areas are transparent; if the background stays a solid colour, it isn’t.
This is especially useful for game sprites, logos, stickers and UI icons, where a stray white box around a character is easy to miss on a white page. Switch to the solid background mode and pick any colour — for example a dark tone close to your game’s scene — to spot leftover halos, semi-transparent fringes or pixels that weren’t fully removed.
The tool is a visual preview, not an automatic analyzer: you judge the result by eye. A JPG can never contain transparency, so convert to PNG or WebP if you need it. The image is displayed straight from your device without any upload, so it’s safe to check unreleased artwork.

❓ FAQ
Does it automatically tell me if the image is transparent?
No. It shows the image over a checkerboard or a colour of your choice so you can judge visually; it doesn’t analyze the pixels for you.
Can I check a JPG file?
The tool accepts PNG and WebP. JPG doesn’t support transparency at all, so a JPG background is always solid.
Why do I see a faint white outline on a dark background?
That’s a halo left by anti-aliased edges that were blended with white before the background was removed. Clean up the edges or re-export on a transparent canvas.
Is my image uploaded?
No. The image is displayed directly from your device and never sent to a server.
