PNG and JPEG serve different purposes. Learn when lossless PNG transparency beats JPEG compression, and when JPEG is the obvious choice.

AVIF delivers 30–50% better compression than JPEG using the AV1 codec. Discover why it is the future of web images and how to start using it today.

WebP is a modern image format that delivers superior compression without quality loss. Learn why major browsers now support it and how it improves web performance.

Both shrink images far below JPEG, but they trade off differently on compression, encode speed, and browser support. Here is how to choose.

iPhones save photos as HEIC to save space, but many apps and Windows tools cannot read them. Here is the fastest fix.

Why a PNG of a photo is huge, why a JPEG of a logo looks fuzzy, and how to pick the right one every time.
