JPG vs PNG vs WebP: Which Image Format Should You Use?
Three formats, three different jobs. Here's how to pick the right one based on what's actually in your image.
"Which format should I use" comes down almost entirely to one question: is the image a photo, or is it graphics with sharp edges and flat color (a logo, a screenshot, an icon)? The two situations call for genuinely different formats.
JPG: built for photos
JPG compresses photographic content very efficiently - smooth color gradients, natural textures, complex scenes - which is exactly what most photos are made of. Its weakness is sharp edges and text, which can come out slightly blurred or show visible artifacts ("JPG noise") around hard boundaries, especially at lower quality settings.
PNG: built for graphics, not photos
PNG uses lossless compression, meaning it doesn't discard any detail - every pixel comes back exactly as it went in. That makes it excellent for logos, screenshots, and anything with sharp edges, flat colors, or text, and it supports transparency (a see-through background), which JPG doesn't. The tradeoff is file size: PNG handles photos poorly, producing much larger files than JPG for the same image.
WebP: the modern middle ground
WebP was designed to do both jobs well - it compresses photos more efficiently than JPG at a similar quality level, and it also supports transparency like PNG. For most modern use, especially websites, WebP is often the best default. See our full WebP breakdown for when it's worth switching to.
A simple way to decide
- Photo, no transparency needed → JPG or WebP
- Logo, icon, screenshot, or anything with text or sharp edges → PNG
- Need transparency and smaller file size than PNG → WebP
- Not sure, or need broad compatibility with older software → JPG for photos, PNG for graphics is the safest universal choice
Frequently asked questions
Which format is best for photos?
JPG or WebP - both are designed for photographic content with lots of color gradients, and compress it efficiently without much visible quality loss.
Which format is best for a logo or screenshot with text?
PNG, because it's lossless and handles sharp edges and flat colors (like text and simple graphics) without the blurring that JPG's compression can introduce around hard edges.
Is WebP always better than both?
WebP generally produces smaller files than JPG or PNG at similar quality, and supports transparency like PNG does. Its main drawback is that a small number of older apps and tools still don't support it, though modern browsers all do.
