What does WebP do better than PNG and JPG?
WebP combines the strengths of older formats: the transparency of PNG, the small photographic files of JPG, and the animation of GIF — all in one format, at a smaller size. A WebP image is typically 25–35% smaller than a comparable PNG or JPG, which speeds up pages and improves Core Web Vitals.
Is WebP lossy or lossless?
Both. WebP has a lossy mode that discards some detail for the smallest files, and a lossless mode that preserves every pixel like PNG. That flexibility lets you tune the balance between quality and size for each image.
Does WebP support transparency and animation?
Yes to both. WebP has a full alpha channel, so it keeps transparency exactly like PNG, and it supports animation as a lighter alternative to GIF. You can convert PNG to WebP without losing a transparent background.
Do browsers and apps support WebP?
Every modern browser supports WebP. Some older desktop software and workflows still don't, so when you need a universally compatible file you can convert WebP back to PNG.
When should you use WebP?
Use WebP for images on websites and apps, where smaller files mean faster loads. Keep PNG for lossless editing masters and anywhere WebP isn't supported. For a direct comparison, see PNG vs WebP, or start with what is a PNG.
Frequently asked questions
- Is WebP better than PNG?
- For the web, usually yes — WebP keeps transparency like PNG but at a much smaller size. PNG is still better for lossless editing and maximum compatibility.
- Can WebP be animated?
- Yes. WebP supports animation, making it a smaller, higher-quality alternative to animated GIF.
- Does WebP lose quality?
- Only in lossy mode, where you trade a little detail for a much smaller file. WebP also has a lossless mode that preserves every pixel.
- Do all browsers support WebP?
- Yes. Every modern browser — Chrome, Edge, Firefox, and Safari — supports WebP.
