Comparison guide

WebP vs JPEG vs PNG

Image format decisions affect quality, file size, transparency, text readability, and Core Web Vitals. This comparison helps you choose a publishing format before compressing or resizing an image.

Core differences

Topic Format choice Publishing tradeoff
WebP Modern web images, screenshots, photos, and mixed content. Often smaller at similar visual quality, but check older workflows and download expectations.
JPEG Photos and complex images without transparency. Widely supported and small, but compression can damage text and UI screenshots.
PNG Logos, transparency, line art, pixel UI captures, and lossless screenshots. Sharp and lossless, but can become very large for photos or full-page screenshots.
Text readability PNG or carefully tuned WebP is usually safer for screenshots. JPEG artifacts can make small text look fuzzy.
Toolkits path Use Image Compressor and Resizer to test width, quality, and output size. Review the image at mobile display width before publishing.

How to choose

Format choice

  • Use WebP for most web publishing when compatibility is acceptable.
  • Use JPEG for photos where transparency is not needed.
  • Use PNG for transparent assets, logos, and screenshots where sharp text matters.

Publishing tradeoff

  • Resize to the actual display width before tuning quality.
  • Keep the original image outside the publishing folder.
  • Check alt text and final rendered size, not only file size.

Review boundaries

  • Small files are not automatically better if text becomes unreadable.
  • PNG can be wasteful for large photos.
  • WebP is excellent for websites, but source assets may still need PNG or JPEG archives.

Common mistakes

  • Compressing the only original copy.
  • Choosing JPEG for screenshots with small interface text.
  • Publishing 2400 px images into 720 px containers.
  • Forgetting transparent backgrounds when converting PNG to JPEG.
