PNG vs JPG vs WebP: Which Image Format Is Best?
Choosing the wrong image format makes pages slower or images blurrier than they need to be. Here is how the three most common formats compare.
JPG: best for photographs
JPG compresses photos well and is supported everywhere. It has no transparency and shows artifacts on sharp text or flat graphics. Use it for photos, backgrounds and email attachments. Convert with the PNG to JPG converter.
PNG: best for sharp graphics and transparency
PNG is lossless, so logos, screenshots, icons and diagrams stay crisp. The cost is size: a photo saved as PNG can be several times larger than the same photo as JPG. Use the JPG to PNG converter when you need lossless output.
WebP: best all-rounder for the web
WebP supports lossy and lossless compression plus transparency, and is usually 25-35% smaller than JPG or PNG at similar quality. All current major browsers support it. Try the PNG to WebP and JPG to WebP converters.
Quick decision guide
- Photo on a website: WebP, with JPG as fallback if you must support old software.
- Logo or icon with transparency: SVG if possible, otherwise PNG or WebP.
- Screenshot with text: PNG or lossless WebP.
- Email or print service that asks for JPG: JPG at quality 85-92.
