The case for choosing JPEG over PNG for certain workflows

PNG files are lossless and support transparency, making them ideal for graphics and logos. However, their larger size can slow website load times, cause email delays, and create issues with some platforms. You convert PNG to JPEG when transparency isn't needed and you want a smaller, faster-loading file. JPEG keeps the image clear, shrinks the size, and works smoothly across email, web, and platforms like Instagram or Shopify.

When trading PNGs for JPEGs pays off

  • Webmasters and bloggers: Looking to speed up site load times by reducing image sizes without losing noticeable photo quality.
  • Photographers: Sending client galleries who need smaller files that won't clog inboxes or cause delays during download.
  • Social media managers: Optimizing images for platforms that prefer JPEG for speed and compatibility.
  • E-commerce sellers: Uploading product photos fast while maintaining visual appeal on marketplaces that do not support PNG transparency.
  • Marketers: Preparing email campaigns where attachment size can affect delivery success.
  • Client proofs: If you're sending preview galleries, JPEGs keep load times low without overwhelming the client with file size.
  • Watermarked previews: PNGs are often used for watermarking. Converting to JPEG makes them easier to send and view online.
  • Delivery platforms: JPEGs are more compatible with gallery tool, CRMs, and print labs.
