PNG vs JPG vs WebP: Which Format Should You Use?

The right format depends on what the image must do. Transparency, file size, photo quality, browser support, and later editing all matter.

When this guide helps

  • •You are not sure whether to download or publish PNG, JPG, or WebP.
  • •You need transparent logos or game assets but also care about file size.
  • •You are preparing images for a website, document, shop, or design tool.

Decision steps

  1. 1Use PNG when transparency, crisp line art, logos, UI, or icons matter.
  2. 2Use JPG for photos when a solid background is acceptable and small size matters.
  3. 3Use WebP for modern web delivery when your publishing platform supports it.
  4. 4Convert to PNG when an editor, game engine, or workflow requires PNG input.

Good format choices

  • •Keep a PNG master file for transparent assets.
  • •Use JPG for final photo exports without transparency.
  • •Use WebP for web pages when compatibility is known.

Common mistakes
