  • !The converted JPG image looks washed out → the source PNG likely uses a wider color space than JPG supports
  • !JPG file is much larger than expected → check if the conversion preserved an unnecessarily high resolution

About PNG and JPG

PNG

PNG is a lossless image format with optional alpha transparency, ideal for graphics, screenshots, and assets that need pixel-perfect fidelity. Its main drawback is file size: a photo stored as PNG can be several times larger than the same photo as JPG.

JPG

JPG is the universal photographic format. Its lossy compression produces small files that load instantly on the web and are accepted by virtually every device, CMS, and social platform. For photos without transparency, JPG is almost always the better delivery format.

Common Use Cases

  • Shrink a large PNG photograph so it uploads and loads quickly on a website.
  • Email a photo to someone whose client rejects or balloons PNG attachments.
  • Publish images to social media, which expects JPG and re-compresses everything anyway.
  • Reduce storage use for a library of photos that do not need transparency.
