JPG, PNG, WebP, or HEIC: which format should you use?

A practical guide to choosing image formats before converting photos, screenshots, transparent images, and web assets.

Use JPG for photos

JPG is usually the easiest choice for photos where a small file matters more than perfect pixel preservation.

  • Good for camera photos and blog images.
  • Does not support transparency.
  • Repeated saving can reduce quality.

Use PNG for sharp or transparent images

PNG is useful when edges, screenshots, UI captures, or transparent backgrounds need to stay clean.

  • Good for screenshots and graphics.
  • Supports transparency.
  • Can be larger than JPG for photos.

Use WebP for web delivery

WebP often gives smaller files while keeping good quality, but compatibility requirements should be checked.

  • Useful for websites and social previews.
  • Supports transparency.
  • Keep JPG or PNG copies when maximum compatibility matters.
