JPG vs PNG vs WebP: Which Image Format Should You Use in 2025?
Choosing the wrong image format is one of the most common mistakes web designers and content creators make. Use JPG where PNG would be better and you get blurry logos. Use PNG where JPG would do and your pages load in 5 seconds. Use WebP without a fallback and half your images vanish on old browsers.
This guide breaks down exactly when to use each format with real-world examples.
JPG — The Web Workhorse
JPG compresses photographs into small file sizes while maintaining visually acceptable quality. The compression is lossy — it discards image data the human eye is unlikely to notice — which is why a 4MB camera photo becomes a 300KB JPG without looking drastically different.
Use JPG for: photographs, product images, blog post hero images, social media posts, email attachments.
Never use JPG for: logos (compression blurs sharp edges), screenshots with text (text gets blurry), images that need a transparent background, or images you plan to edit and re-save multiple times.
Pro tip: Save JPGs at 80-85% quality. Most people cannot tell the difference between 85% and 100%, but the file size is 3-4x smaller at 85%.
PNG — When Quality and Transparency Matter
PNG uses lossless compression — no image data is discarded. This makes PNG files larger than JPG for the same image, but every pixel is pixel-perfect. The other key feature is alpha channel transparency — PNG files can have fully transparent, semi-transparent, or opaque pixels.
Use PNG for: logos, icons, brand assets, screenshots with UI elements and text, graphics that need a transparent background, digital art with flat colors, images used in design tools like Figma or Canva.
"If you are not sure whether to use JPG or PNG, ask one question: does this image need a transparent background? If yes, use PNG. If no, JPG is probably better for file size."
WebP — The Modern Standard
WebP was developed by Google to improve on both JPG and PNG for web use. It supports lossy compression (like JPG) AND lossless compression (like PNG) AND transparency — all in one format, with files typically 25-34% smaller than JPG at the same visual quality.
As of 2025, WebP is supported by all modern browsers covering over 95% of internet users. For new projects, WebP is almost always the best choice for web images.
Use WebP for: website images where page speed matters, progressive web apps, any situation where you would use JPG or PNG but want smaller files.
Avoid WebP for: email attachments (many email clients don't support it), very old browser compatibility requirements, or when the image will be edited in software that doesn't support WebP.
