What is WebP?
WebP is a modern image format developed by Google. It uses advanced compression algorithms to produce images that are:
- 25–35% smaller than JPEG at the same visual quality
- Up to 80% smaller than PNG for images with transparency
- Supported by all modern browsers (Chrome, Firefox, Safari, Edge)
In short: WebP gives you better quality at a smaller file size. It's the best format for almost every web image.
WebP vs JPEG vs PNG — Which Should You Use?
| Format | Best For | Transparency | File Size |
|---|---|---|---|
| JPEG | Photos | No | Medium |
| PNG | Graphics, logos | Yes | Large |
| WebP | Everything | Yes | Small |
| AVIF | Everything | Yes | Smallest |
WebP supports both lossy and lossless compression, and it supports transparency (like PNG). It's essentially a better version of both JPEG and PNG combined.

- Balanced (80%) — best size/quality ratio for most images
- Click Convert and download your WebP files
You'll see the exact file size reduction for each image, with a before/after visual comparison.
Does WebP Work in All Browsers?
Yes. As of 2024, WebP is supported by 97%+ of all browsers worldwide, including Safari (since version 14). You can safely use WebP for all web images.
When to Use Lossless WebP
Use lossless WebP when:
- You're converting logos or icons that need pixel-perfect edges
- You're archiving images and need exact reproduction
- You're converting screenshots with text
For photos and general web images, lossy WebP at 80–85% is the right choice.
