What is the difference between “JPG” / “JPEG” / “PNG” / “BMP” / “GIF” / “TIFF” Image?

Question

I have seen many types of image extensions but have never understood the real differences between them. Are there any links out there that clearly explain their differences?

Answer 1

PNG supports alphachannel transparency.

TIFF can have extended options I.e. Geo referencing for GIS applications.

I recommend only ever using JPEG for photographs, never for images like clip art, logos, text, diagrams, line art.

Favor PNG.
