JPG to PNG: Everything You Need to Know
JPG and PNG are the two most common image formats on the web, but they serve very different purposes. Converting from JPG to PNG is a common task — and understanding when it makes sense (and when it doesn't) will save you both storage space and image quality.
What Is the Difference Between JPG and PNG?
JPG (Joint Photographic Experts Group) uses lossy compression — it discards some image data to reduce file size. PNG (Portable Network Graphics) uses lossless compression, preserving every pixel exactly. This means:
- JPG: Smaller files, good for photographs, slight quality loss
- PNG: Larger files, perfect quality, supports transparency
When Should You Convert JPG to PNG?
- You need a transparent background. JPG cannot store transparency. If you need to remove a background or overlay an image on a coloured surface, PNG is required.
- You are editing the image repeatedly. Each time you save a JPG, it recompresses and loses more quality. Converting to PNG before editing prevents this accumulation of artefacts.
- The image contains sharp lines or text. PNG handles logos, screenshots, and diagrams far better than JPG, which introduces visible blurring around edges.
- You need exact colour reproduction. PNG is lossless — colours are preserved exactly as they appear in the original.
What to Expect Quality-Wise
Converting a JPG to PNG does not recover quality that was lost during the original JPG compression. If the source JPG was saved at low quality, the resulting PNG will be a lossless copy of that low-quality image — not a restoration. Always start from the highest-quality source available.
File Size After Conversion
A PNG version of a JPG photograph will typically be 2–5× larger in file size. This is expected — PNG does not compress photographic content as efficiently as JPG. For web use where file size matters, PNG is better suited to graphics and screenshots, while JPG remains ideal for photographs.
