Best Image Formats Explained

Every image format makes a different trade-off between file size, quality, and compatibility. Understanding those trade-offs makes it much easier to pick the right one for a given job, instead of defaulting to whatever your camera or design tool happened to save.

JPG remains the default choice for photographs because it compresses smoothly and is supported everywhere. PNG is the better pick when you need transparency or crisp edges, such as logos and screenshots. WebP tends to beat both for web use, often producing smaller files at similar visual quality. AVIF pushes compression even further, though browser and tool support is still catching up.

In practice, the fastest way to decide is to try a couple of formats on your actual image and compare the resulting file size and quality side by side — which is exactly what the ConvertImageNow converter is built for.
