Transparent PNG Checker
Confirm your PNG really has a transparent background.
What counts as transparent
Every pixel has an alpha value from 0 (fully see-through) to 255 (fully solid). This tool reads those values and reports how much of your image is transparent. Cut-out artwork for stickers or apparel should have its whole background at alpha 0, with the corners see-through.
If your image is not transparent
- Re-export from your design tool as a PNG or WebP with the background layer hidden.
- JPG never supports transparency — switch formats.
- Watch for a stray solid background layer left switched on.
Frequently asked questions
How can I tell if a PNG really has a transparent background?
Upload it here — the tool reads the image’s alpha channel and shows the exact percentage of transparent pixels, plus a checkerboard preview so you can see through the transparent areas.
My JPG looks like it has a white background — can I make it transparent?
JPGs can never be transparent; they always have a solid background. You would need to remove the background and save as PNG or WebP. This tool will tell you a JPG has no transparency.
Why does this matter for print-on-demand?
POD products (like shirts and stickers) print your artwork directly onto the item. If the background is not transparent, a solid rectangle prints around your design instead of just the artwork.
