HEIC to WebP
Best quality at smallest file size
Convert to WebPWant the smallest possible file size without sacrificing quality? WebP is the answer. Google's modern image format offers the best of both worlds: excellent compression that beats JPG, with quality that rivals PNG.
This guide shows you how to convert HEIC to WebP for optimal web performance. If you're building a website or optimizing images for fast loading, WebP should be your go-to format.
Why WebP?
WebP was developed by Google specifically for the modern web. Here's why it's worth considering:
1. Significantly Smaller Files
WebP produces files that are 25-35% smaller than equivalent JPG images at the same quality level. That means faster page loads and less bandwidth usage.
2. Excellent Quality
At the same file size, WebP produces noticeably better quality than JPG. Less compression artifacts, better color accuracy, and sharper details.
3. Flexibility
WebP supports both lossy compression (like JPG) and lossless compression (like PNG). It also supports transparency, making it versatile for all image types.
4. Better Compression Algorithm
WebP uses VP8/VP9 compression technology, which is more efficient than JPG's 30-year-old DCT-based compression.
File Size Comparison
Real-world example with a 12MP photo:
| Format | Quality | File Size | vs JPG |
|---|---|---|---|
| JPG | 80% | 2.1 MB | - |
| WebP | 80% | 1.4 MB | -33% |
| WebP | 90% | 1.8 MB | -14% |
These savings add up quickly when you're optimizing dozens of images for a website.

- 90% - Higher quality, slightly larger files.
- 70% - Maximum compression when file size is critical.
Step 5: Convert and Download
Click Convert, then download your WebP files individually or as a ZIP.
WebP Quality Settings
WebP quality works similarly to JPG, but produces better results at the same setting:
| Setting | Best For | File Size |
|---|---|---|
| 90-100% | Photography sites, portfolios | Larger |
| 80% | Most websites, blogs | Medium |
| 70% | Thumbnails, previews | Small |
| 60% | Maximum compression needed | Smallest |
Unlike JPG, WebP maintains quality better at lower settings, so you can often use lower values without noticeable degradation.
Browser Compatibility
WebP is supported by:
- Chrome - Full support since 2010
- Firefox - Full support since 2019
- Safari - Full support since 2020 (macOS Big Sur, iOS 14)
