JPG vs PNG vs WebP: Which Should You Actually Use?
Most people use whatever image format their phone, camera, or screenshot tool happens to save by default, without ever thinking about it — and most of the time that's fine. But if you've ever wondered why some images load faster than others, why a logo looks blurry after conversion, or why a colleague asked you to "send it as a PNG instead," the answer comes down to a genuine, practical difference between these three formats.
JPG: the default for photos
JPG uses lossy compression, meaning it throws away some detail the eye is least likely to notice in exchange for a much smaller file. For photographs — with their gradual color transitions and natural detail — this trade-off is usually invisible at normal viewing sizes, which is exactly why it's the default format for cameras and phones.
JPG's real limitation: no transparency support, and it handles sharp edges (like text or line art) poorly — compression artifacts show up as blurring or blocky patterns around hard edges, which is why a JPG screenshot of a document often looks slightly fuzzy around the text.
PNG: the default for screenshots, logos, and anything needing transparency
PNG uses lossless compression — every pixel is preserved exactly. This makes it the right choice for anything with sharp edges or flat colors: screenshots, logos, icons, and any graphic with a transparent background. The trade-off is size: a PNG of a photograph is typically much larger than the equivalent JPG, since lossless compression can't take advantage of the same detail-discarding tricks.
WebP: the modern all-rounder
WebP is a newer format that supports both lossy and lossless compression, plus transparency — essentially combining what JPG and PNG each do well into one format. A WebP photo at similar visual quality is typically 20-35% smaller than the equivalent JPG, and a WebP graphic with transparency is often 60-90% smaller than the equivalent PNG.
The only real limitation is compatibility with very old software that hasn't been updated to support it — but every current browser, and most modern image-editing tools, handle WebP natively. For anything destined for the web, it's now the better default over both JPG and PNG.
A simple decision guide
• Photo, going on a website: WebP (fallback to JPG only for legacy compatibility needs) • Photo, need maximum compatibility with older software: JPG • Screenshot, logo, or icon with transparency, going on a website: WebP • Screenshot, logo, or icon, need maximum compatibility or a lossless master copy: PNG • Archiving an image you might edit further: PNG (lossless, so no quality is lost before you've even started editing)
