Best Image Formats for Web (PNG vs JPG vs WebP vs AVIF)

PNG vs JPG: the classic trade-off

PNG is lossless and supports transparency — ideal for logos, UI, and graphics with sharp edges.

JPEG is lossy but much smaller for photographs. It does not support transparency, so PNG→JPEG conversions need a background fill.

WebP and AVIF: modern web formats

WebP offers strong compression for both photos and graphics. Lossless WebP preserves screenshot text without blur.

AVIF typically beats JPEG and WebP on photo compression at equal visual quality — great for hero images and galleries.

Always provide fallbacks: AVIF → WebP → JPEG for maximum browser coverage.

Smart compression without visible loss

Do not use one quality setting for every image. Photos tolerate more compression than screenshots with small text.

Resize before compressing when displaying at smaller dimensions on the page.

Automated routing (photo → AVIF, UI → lossless WebP) saves time and avoids format mistakes.
