WebP vs JPG vs PNG: Which Image Format Should You Use?
Understand the differences between JPG, PNG, and WebP so you always choose the right format for web, print, and applications.
Choosing the wrong image format can mean unnecessarily large files, quality loss, or compatibility issues. Here is everything you need to know to pick the right format every time.
JPG (JPEG)
Best for: Photographs and real-world images with many colours. JPG uses lossy compression, meaning it discards some image data to achieve small file sizes. At 80–90% quality, photos look nearly identical to the original at a fraction of the size. JPG does not support transparency.
Use JPG when: Sharing photos, uploading profile pictures, sending images via email or WhatsApp, submitting passport photos to government portals.
PNG
Best for: Graphics, logos, screenshots, and images requiring transparency. PNG uses lossless compression — no quality is lost on save. PNG files are typically 2–5× larger than equivalent JPGs. Supports transparent backgrounds.
Use PNG when: Logos, icons, UI screenshots, graphics with text, or any image where you need a transparent background.
WebP
Best for: Web images where you want JPG-like quality with even smaller file sizes. Google developed WebP to be 25–35% smaller than JPG at equivalent quality. Modern browsers all support WebP. Supports both lossy and lossless modes, and transparency.
Use WebP when: Optimising website images for fast page loading. Not ideal for forms or portals that require JPG.
