JPG vs PNG vs WebP

The right image format depends on what the image contains and where it will be used. Choosing the wrong format can make files much larger than necessary.

JPG

JPG is best for photographs and realistic images with many colors. It uses lossy compression, which means it discards some visual information to reduce file size. A moderate quality setting can make photos much smaller with little visible difference.

JPG does not support transparency, so it is not ideal for logos, icons, or cutout graphics that need a transparent background.

PNG

PNG is best for screenshots, diagrams, interface graphics, logos, and images with transparency. It preserves sharp edges and text well, but it can be large for photographs because it is commonly used as a lossless format.

If a PNG is a full-color photo without transparency, converting it to JPG or WebP may reduce file size significantly.

WebP

WebP is a modern web format that supports lossy compression and transparency. It is often smaller than JPG or PNG for similar visual quality, which makes it useful for websites and web apps.

The main tradeoff is workflow compatibility. Some older systems or upload forms still expect JPG or PNG.

Quick decisions

• Use JPG for photos when compatibility matters.
• Use PNG for screenshots and transparent graphics.
• Use WebP for modern websites when smaller files are the priority.
• Keep source files before converting or compressing.
