JPG vs PNG vs WebP

Format comparison

When to use JPG

JPG is a practical choice for photographs and other images with many colors and smooth tonal changes. Lossy compression discards some information to reduce file size. At sensible quality settings, the change may be difficult to notice; at aggressive settings, blockiness, ringing, and smeared detail can appear.

JPG does not support transparency. Converting a transparent image to JPG requires filling those areas with a solid color, commonly white.

When to use PNG

PNG preserves image data losslessly and supports transparent or partially transparent pixels. It is a strong choice for logos, diagrams, interface graphics, screenshots, and images with sharp text or flat color.

Photographic PNG files can be much larger than JPG or WebP because lossless compression must preserve every decoded pixel exactly.

When to use WebP

WebP supports both lossy and lossless encoding as well as transparency. For websites, it often produces smaller files than comparable JPG or PNG output while maintaining useful visual quality.

Modern browsers support WebP broadly. Some older editing, printing, or submission workflows may still prefer JPG or PNG, so confirm the destination’s accepted formats.

Conversion is not always reversible

Saving a JPG as PNG does not restore detail previously removed by JPG compression. It usually produces a larger file containing the same visible artifacts. Keep an original high-quality source or master file whenever possible.

Browser-based conversion commonly creates a new encoded image without the original EXIF or other metadata. Preserve the source if camera settings, dates, location, color profiles, or editing history matter to you.
