What is the difference between JPG and PNG?
JPG is usually best for photos and uses lossy compression. PNG supports transparency and is useful for graphics, screenshots and logos, but files can be larger.
What is WebP?
WebP is a modern image format for the web. It supports lossy and lossless compression, transparency and animation, and it often creates smaller files than JPG or PNG.
What is AVIF?
AVIF is a modern image format that can create very small files with strong compression. It is useful when the target browser or platform supports it.
Is WebP better than JPG?
Often, but not always. WebP can be smaller for web images, while JPG remains widely supported and may be required by some upload forms or older systems.
Is WebP better than PNG?
WebP can be smaller and still support transparency. PNG remains a strong choice for exact graphics, simple images and workflows that require PNG.
Is AVIF better than WebP?
AVIF can be smaller, especially for some photos, but WebP is usually more broadly compatible. Test both when compatibility and quality matter.
Which image format has the smallest file size?
There is no single winner for every image. AVIF or WebP may be smallest for many web images, while PNG can be better for simple transparent graphics.
Which image format is best for websites?
WebP is a practical default for many websites. Keep JPG or PNG when compatibility, transparency, editing workflow or upload requirements make them a better fit.
Which image format supports transparency?
PNG, WebP and AVIF can support transparency. JPG does not support transparency, so transparent areas need a background color before exporting as JPG.
Should I convert JPG to WebP?
For many website photos, converting JPG to WebP can reduce file size. Keep a JPG copy when the destination requires JPG or when you need maximum legacy compatibility.
