Common questions
Will image compression reduce quality?
Lossy compression can reduce detail, but a reasonable quality setting balances file size and visual clarity.
Should I use PNG, JPEG, or WebP?
Use JPEG or WebP for photos, PNG or WebP for transparency, and WebP when web performance is the priority and compatibility is acceptable.
Where are compressed images useful?
They are useful for web pages, blog images, product photos, email attachments, and social uploads where smaller files load faster.
