Transparency note
Converting a JPG to PNG does not magically add transparency because JPG files do not contain transparent pixels.

Frequently asked questions
Will JPG become transparent after converting to PNG?
No. JPG has no transparency data, so converting to PNG preserves the visible image but does not create a transparent background.
Does JPG to PNG improve quality?
No. Conversion changes the file format; it cannot restore quality already lost in the JPG.
Why is the PNG larger than the JPG?
PNG is lossless, so PNG output can be larger than JPG for photos.
Is my image uploaded?
No. Conversion runs in your browser.
