Efficient Image Formats
Compare and choose optimal image formats (e.g., WebP, AVIF, JPEG) for different use cases to balance quality and file size.
Why Image Formats Matter
Choosing the right image format is crucial for web performance. It's a balance between image quality and file size.
Smaller image files mean faster loading times, which improves user experience and can even boost your search engine ranking.
JPEG: For Photographs
JPEG (Joint Photographic Experts Group) is ideal for photographs and complex images with many colors. It uses lossy compression, meaning some image data is permanently removed to reduce file size.
While it offers great compression for photos, repeated saving can degrade quality. JPEG does NOT support transparency.
