What is HEIC to WebP conversion?
Nothing in this conversion passes through JPG, and that is precisely the point. Decoding HEIC, encoding to JPG, decoding again, and re-encoding to WebP applies two independent rounds of lossy quantization; going straight from one format to the other is a single decode-encode hop.
Both sides comfortably outperform JPG on compression but serve different ecosystems — HEIC is Apple's capture format built on HEVC, defined by ISO/IEC 23008-12, while WebP is Google's delivery format built on VP8 intra-frame coding per RFC 6386 — and this conversion is the bridge between them. Anyone who shoots on iPhone and publishes to the web is the audience here: content creators, bloggers, small e-commerce operators, web developers. A typical iPhone 15 HEIC weighs 2-3 MB; at 90% quality the WebP lands between 400 and 800 KB, which loads nearly instantly on modern connections and pulls Largest Contentful Paint down with it. Photography portfolios, travel blogs, food blogs, and product galleries all feel the difference in their Core Web Vitals scores. Metadata transfers cleanly, since both formats support EXIF and alpha channels — orientation, capture date, and camera settings all survive. Browser coverage per caniuse.com/webp spans Chrome, Firefox, Safari 14+, and Edge, effectively every browser users actually run in 2026. What WebP is bad at is everything outside a browser: email newsletters (most clients refuse to render it inline), print-lab uploads, and some legacy photo managers that reject it. Use HEIC-to-JPG when any of that matters, and HEIC-to-PNG for editing masters.
Why convert HEIC to WebP?
- WebP is 25-35% smaller than JPG, speeding up page loads and reducing bandwidth costs
- All modern browsers (Chrome, Firefox, Safari 14+, Edge) support WebP natively
- Better compression than JPG while maintaining higher visual quality
- Ideal for website images, blog posts, and online portfolios from iPhone photos

Frequently asked questions
Can I use WebP images everywhere?
WebP works in all modern browsers but is not supported by some older software and printing services. If broad compatibility is more important than file size, use JPG instead.
Is HEIC to WebP better than HEIC to JPG for my blog or portfolio site?
Yes, for web use. WebP files are 25-35% smaller than equivalent JPGs at the same visual quality, which means faster page loads and better Core Web Vitals scores. All modern browsers support WebP. Use HEIC to JPG only if you also need the images to work in older desktop apps.
Should I convert to WebP or AVIF for my website?
WebP has broader browser support (Safari 14+ vs Safari 16+ for AVIF) and faster encoding. AVIF achieves 20-35% better compression than WebP. For maximum compatibility with good compression, use WebP. For cutting-edge optimization, serve AVIF with a WebP fallback using the HTML picture element.
Can I use HEIC to WebP for my WordPress or Shopify site?
Yes. Convert your iPhone photos to WebP before uploading. WordPress supports WebP natively since version 5.8, and Shopify accepts WebP for product images. Both platforms will serve the WebP directly to supporting browsers, delivering faster page loads than JPG uploads.
Will my iPhone photo look the same on a Retina display after converting to WebP?
Yes. At 90% quality, WebP preserves sufficient detail for Retina and high-DPI displays. The lossy compression targets imperceptible detail, and the resulting image is visually identical to the HEIC source at both standard and Retina pixel densities.
Does HEIC-to-WebP avoid the quality loss of going through JPG first?
Yes — and that is the main reason to prefer this direct path. Decoding HEIC, encoding to JPG, decoding the JPG, and re-encoding to WebP applies two independent rounds of lossy quantization. Converting HEIC straight to WebP is a single decode-encode hop, which preserves more detail at the same final file size.
