Why Convert to WebP?
WebP is Google's image format built specifically for the web. It typically produces files 25-35% smaller than JPEG at the same visual quality, and significantly smaller than PNG while still supporting transparency. If you're optimising a website, switching to WebP is one of the easiest performance wins available.
WebP supports both lossy compression (like JPEG) and lossless compression (like PNG), plus transparency and even animation. It's essentially one format that can replace JPEG, PNG, and GIF for most web use cases.
Browser support now covers over 97% of users globally — Chrome, Firefox, Safari, Edge, and Opera all handle WebP natively. The only holdouts are very old browsers that represent a tiny fraction of traffic.
File Size Comparison
| Image Type | JPEG Size | PNG Size | WebP Size | Savings vs JPEG |
|---|---|---|---|---|
| Photo (2000×1500) | 450 KB | 2.8 MB | 320 KB | ~29% |
| Screenshot (1920×1080) | 280 KB | 1.5 MB | 180 KB | ~36% |
| Logo with transparency | N/A | 85 KB | 32 KB | 62% vs PNG |
| Product photo (800×800) | 120 KB | 650 KB | 82 KB | ~32% |
| Blog hero (1200×630) | 180 KB | 1.1 MB | 125 KB | ~31% |
What this means for you: Switching to WebP across a typical website can cut total image weight by 25-35%, directly improving page load times and Core Web Vitals scores.
When NOT to Use WebP
Print Workflows
Most print software doesn't support WebP. Stick with PNG or TIFF for anything heading to a printer. Convert to WebP only for the web version.
Email Newsletters
Many email clients (especially older Outlook versions) don't render WebP. Use JPEG or PNG for email images to ensure everyone sees them.
Archival Storage
For long-term photo archives, JPEG is more universally supported. WebP is great for serving, but keep originals in a widely-supported format.
Image Editing Chains
Not all image editors support WebP natively. If you'll be editing the file further, work in PNG or PSD and export to WebP as the final step.
WebP vs AVIF: The Next Generation
| Feature | WebP | AVIF |
|---|---|---|
| File size (vs JPEG) | 25-35% smaller | 50%+ smaller |
| Browser support | 97%+ | ~92% |
| Encoding speed | Fast | Slow (5-10× slower) |
| Transparency | Yes | Yes |
| Animation | Yes | Yes |
| HDR support | Limited | Full 10/12-bit |
WebP is the safe choice today — wider support and faster encoding. AVIF offers better compression but slower encoding and slightly less browser coverage. The ideal setup is a <picture> element serving AVIF with WebP fallback.
