Resizing and image quality
Reducing dimensions removes pixels and usually makes a file smaller. Enlarging an image cannot restore detail that was not in the original, so large increases may look soft. JPEG and WebP quality settings also affect appearance and file size.

JPG uses lossy compression to create small files and works best for photographs, but it does not support transparency. PNG uses lossless compression, preserves sharp details and transparency, and is best for graphics, logos, and screenshots, though files are often larger. WebP can produce smaller files than JPG or PNG, supports transparency, and is a strong choice for modern websites. Choose JPG for photos and broad compatibility, PNG when exact detail or transparency matters, and WebP when reducing web page file size is the priority.
