HEIC to WebP Converter

Why Convert to WebP?

WebP is Google’s modern image format designed specifically for the web. It delivers 25-35% smaller file sizes than JPG at comparable visual quality, supports transparency (unlike JPG), and even handles animation (unlike PNG). If you run a website, blog, or online store, WebP should be your default image format.

Since iPhone photos are captured in HEIC format, you need a conversion step before using them on the web. This tool converts HEIC directly to WebP — no intermediate JPG step needed, which avoids double compression quality loss.

WebP vs JPG: Why WebP Wins for the Web

Metric	JPG	WebP	Advantage
File size (same quality)	3.5 MB	2.3 MB	35% smaller
Transparency	❌	✅	WebP
Animation	❌	✅	WebP
Browser support (2025)	100%	97%+	Nearly equal
WordPress/CMS support	✅	✅	Both

Google recommends WebP as the primary image format for web pages. Google PageSpeed Insights and Lighthouse audits specifically flag JPG images that could be served as WebP.

Ideal Use Cases

E-Commerce Product Photos

Online stores typically display 5-10 product images per page. Converting from HEIC to WebP instead of JPG can save 2-5 MB per page load — directly improving your Google Core Web Vitals scores and customer experience.

Blog and Content Sites

If you photograph recipes, travel destinations, or DIY projects with your iPhone, WebP gives you the best balance of quality and page speed. Faster pages rank higher in search results.

Portfolio and Gallery Sites

Photographers and designers can showcase their iPhone work in WebP format. At quality 85-90%, WebP is visually indistinguishable from the HEIC original while being significantly smaller.

Quality Settings Guide

• Quality 85-90%: Recommended for most web use. Visually identical to the original, optimal file size.
• Quality 95-100%: Use when quality is paramount (photography portfolio, detailed product shots).
• Quality 70-80%: Aggressive compression for thumbnail galleries or low-bandwidth audiences.

How It Works

Our converter uses WebAssembly to decode your HEIC file locally, then re-encodes it as WebP using your browser’s native Canvas API. Your files never leave your device — making this the most private HEIC-to-WebP converter available.

The entire process is:

1. Drop your HEIC files onto the converter
2. Adjust quality if needed (default 80% is a good starting point)
3. Download individual WebP files or all at once as a ZIP
