Image Editing Export and File Formats

Question 1

Which file format is best for photographs that need to be shared on the web with small file sizes?

Accepted Answer

Question 2

What type of compression does the PNG format use?

Accepted Answer

Lossless compression that retains all pixel data

Answer

PNG uses lossless compression, meaning no image data is discarded and the file can be re-saved repeatedly without quality loss.

Question 3

What is the main advantage of the WebP format over JPEG for web use?

Accepted Answer

It provides better compression with comparable quality, resulting in smaller file sizes

WebP achieves significantly smaller file sizes than JPEG at similar visual quality, reducing page load times for websites.

Question 4
