FAQ
Frequently Asked Questions
Both are used. 'JPEG' is the formal acronym, while 'jpeg' (especially lowercase) is common for the file extension (.jpg) and informal usage.
There is no technical difference. .jpg was used due to older Windows systems limiting extensions to three letters. Both refer to the same JPEG format.
No. JPEG is ideal for photographs and complex images with gradients. It is not suitable for simple graphics, logos, or text, where lossless formats like PNG are better, as JPEG compression can create artifacts.
Yes, JPEG is a 'lossy' compression format. It permanently discards some image data to reduce file size. The quality loss can be controlled with compression settings, but some detail is always lost.
