Tips for HEIC to WebP conversion
Quality 80 for Web
For most web images, quality 80 provides an excellent balance — visually similar to JPG quality 90 but 25–35% smaller file size.
Use Lossless for Graphics
For graphics, logos, or screenshots with sharp edges, use lossless WebP mode. It preserves every pixel while still being smaller than PNG.
Enable Transparency
If your HEIC image has transparent areas, make sure transparency is enabled in the conversion settings to preserve alpha channels.
Test Multiple Qualities
Try converting at different quality levels (70, 80, 90) and compare. Often, lower quality settings look identical to the eye but are much smaller.
Serve WebP on Your Site
Configure your web server or CDN to serve WebP images. Most modern CDNs can automatically convert and serve WebP to supported browsers.
Provide JPG Fallback
For maximum compatibility, serve WebP with a JPG fallback using the <picture> element. This ensures older browsers still display your images.
