JPG and PNG — What Is the Difference?
Think of JPG like a painting where the artist smudges some tiny details to save paint. The result looks great from a distance, but if you zoom in very close you might see tiny blurry patches. That smudging is called lossy compression.
PNG is like a perfect photograph — every single pixel is saved exactly as it was. No detail is lost. That is called lossless compression.
When Should You Convert JPG to PNG?
1. You Need a Transparent Background
JPG cannot do transparency. If you need your image to sit on a coloured background without a white box around it — like a logo, a sticker, or a product photo — you need PNG.
2. You Are Going to Edit the Image Again
Every time you save a JPG, it loses a tiny bit of quality. If you edit and re-save ten times, it gets noticeably worse. Convert to PNG first, do all your edits, then export a final JPG when you are done.
3. The Image Has Text or Sharp Lines
Logos, screenshots, infographics, and QR codes all have sharp edges that JPG makes slightly blurry. PNG keeps those edges crisp.
When Should You NOT Convert JPG to PNG?
Converting a JPG to PNG does not magically improve quality. It only stops future quality loss. The original smudging from when the JPG was first created stays forever.
Also, PNG files are much larger. A photo that is 200KB as a JPG might become 1.5MB as a PNG. If you just want a smaller file, use our Image Compressor instead.
