Kaj se zgodi, ko JPG postane PNG

Izvorni format

JPG uses lossy compression and does not support transparency.

Ciljni format

PNG uses lossless compression and supports full transparency.

Kaj se spremeni

The JPG pixels are decoded and written using PNG compression and color capabilities.

Kaj se ohrani
Pixel dimensions and visible composition are preserved unless resize or crop settings are selected.
Kaj se lahko izgubi
Layers, editable vectors, camera-raw controls, animation, high bit depth, and metadata are preserved only when PNG supports them.
Vpliv kodeka in kakovosti
Writing PNG without further lossy compression avoids additional codec loss, but it does not restore detail discarded by the JPG encoding.
Praktične omejitve
Multi-page, layered, animated, camera-raw, or very large images may be flattened, reduced to one frame, or rejected if the decoder cannot safely read them.
