About HEIC to WebP Converter
WebP was built by Google for the modern web. At equivalent visual quality, a WebP file is typically 25 to 35 percent smaller than JPG and often smaller than PNG — which means faster page loads, lower bandwidth bills, and better Core Web Vitals scores. Every current version of Chrome, Edge, Firefox, and Safari understands WebP natively, so unlike HEIC you can embed the output directly with an `<img>` tag and expect it to render everywhere.
Converting HEIC to WebP is the sweet spot for publishing iPhone photos to a website, blog, Shopify store, Ghost newsletter, or Next.js image CDN. You keep most of the storage efficiency that made HEIC attractive on the iPhone, gain broad browser support that HEIC still lacks on the desktop, and unlock features JPG cannot provide — full alpha transparency and even animated frames.
FormatFuse runs the conversion entirely in the browser: HEIC is decoded with WebAssembly, then re-encoded through `@jsquash/webp` with a quality setting you control. No photos are uploaded to a server, so you can safely batch-process unreleased product shots, client deliverables, or personal memories before they go live.

HEIC to WebP — Frequently Asked Questions
How much smaller are WebP files compared to JPG?
At the same perceived quality, WebP is typically 25-35% smaller than JPG and often matches HEIC's compression efficiency. For an image-heavy blog post or product page, that size reduction translates directly into faster load times and better Lighthouse scores.
Do all browsers support WebP?
Yes. WebP is supported natively by Chrome, Edge, Firefox, Safari (14+), Opera, and every major mobile browser. That is a major advantage over HEIC, which still has limited browser support and typically requires conversion before publishing.
Does HEIC to WebP preserve transparency?
Yes. WebP supports a full alpha channel, so any transparency present in the source HEIC is carried through. That makes WebP a good choice for product shots on white backgrounds, UI captures, and graphics pulled from iPhone screenshots.
Can I control the WebP quality?
You can. Choose Lossless for a pixel-perfect master copy, or drop into the quality slider to tune the balance between size and fidelity. Quality 80-90 is the typical sweet spot for web photos — visually indistinguishable from the original at a fraction of the bytes.
Is this better for websites than HEIC or JPG?
For almost all public web use cases, yes. HEIC lacks cross-browser support, and JPG cannot compete with WebP on file size or features (no transparency, no animation). Converting HEIC to WebP gives you broad compatibility, smaller bytes, and modern format capabilities in one step.
