Transparent PNG to JPG — fill background online
JPEG has no alpha channel. Transparent PNGs forced into JPG often get black or speckled holes where transparency was. This page lays down white or your chosen background color first, then exports JPG — for forms, print shops, or platforms that only accept JPEG.

Design tools export transparent PNGs all the time, but banks, government portals, and some shops want JPG only. Renaming or blind converting leaves transparent pixels with nothing to encode — black is a common accident.
Fix it by painting an explicit background. White is the default; light logos may need a dark fill for contrast.
If you truly need transparency, stay on PNG/WebP or ask the recipient to accept those formats.
How to convert
- Upload transparent PNG
- Pick fill color (white by default)
- Preview — no black edges — then download JPG
Filling the background first helps you
- Avoid black or dirty holes where transparency was.
- Pick a fill color — not only forced white.
- Preview before download so the background looks right.
Scenarios
- Logo on clear background, form accepts JPG only
- Cut-out product on white for marketplace rules
- Print shop rejects PNG
Tips
- Light artwork on dark fill; dark artwork on white.
- Soft shadows on a fill may show halos — trim in design tools if needed.
- Skip JPG entirely when transparency still matters.
Before and after
| Input | Output | Note |
|---|---|---|
| Transparent logo → JPG blind | Often black background | The usual bug |
| Same logo with white fill here | Clean white JPG | Form-friendly |
