PNG to JPG: Compress Images the Right Way

PNG to JPG: When Compression Is the Right Move

PNG files are lossless and large. JPG files are compressed and small. Converting from PNG to JPG is one of the fastest ways to reduce an image's file size — but it comes with a permanent quality tradeoff you should understand before converting.

Why Convert PNG to JPG?

  • File size reduction: A photographic PNG can shrink by 60–80% when converted to JPG. This matters enormously for web page load times and storage limits.
  • Email and upload limits: Many platforms cap attachments at 5–25 MB. JPG is the easiest way to stay under the limit without cropping.
  • Social media sharing: Most platforms re-compress PNGs automatically — converting to JPG first gives you control over the quality setting.
  • Web performance: Smaller images mean faster pages, better Core Web Vitals scores, and improved SEO.

When Not to Convert

Avoid converting PNG to JPG when:

  • The image has a transparent background — JPG replaces transparency with a solid colour (usually white)
  • The image contains text, logos, or sharp geometric shapes — JPG compression blurs these edges noticeably
  • You intend to edit and re-save the image repeatedly — each JPG save recompresses and degrades quality

Understanding Quality Settings

JPG converters typically offer a quality slider from 1 to 100. Here is a practical guide:

  • 90–100: Near-lossless, minimal compression benefit, best for professional print
  • 75–85: Recommended for web images — good quality, significant size reduction
  • 50–70: Visible artefacts, best only for thumbnails or previews
  • Below 50: Heavy distortion, use only when file size is critical
