How to use Transparent Image Background Filler
- Choose one or more PNG or WebP images that already contain transparency.
- Enter a solid HEX background color and select PNG or JPG output; set JPEG quality when using JPG.
- Fill the transparent areas, inspect the result, and download the converted image files.
What this tool does
This composites transparency; it does not remove a background.
Example
A transparent logo exported as JPG with background #ffffff is composited over white because JPG cannot store transparent pixels.
Frequently asked questions
Does this remove a background from an ordinary photo?
No. It puts a chosen solid color behind existing transparency. It does not identify or remove the background of an opaque photo.
Can I keep transparency in the output?
Choose PNG to retain alpha where it remains in the image. Choosing JPG composites the image onto the selected color; animated input is reduced to a still frame.
