Before
After
This photo had a transparent area — in JPG that area now shows as white (JPG can't be transparent).
Your photo stays on your phone — it is never uploaded anywhere
How it works
Choose a photo → the tool detects its format, tap the other format's button to convert. Converting to JPG fills any transparent area with white (so a transparent signature never turns black). Nothing is ever uploaded.
