Why Convert HEIC to WebP for Your Website?
WebP is the image format purpose-built for the modern web. Developed by Google and now supported by every major browser, WebP produces images that are 25–35% smaller than equivalent JPG files at visually identical quality. For website owners and bloggers who regularly upload iPhone photos, converting HEIC to WebP is one of the most impactful image optimisation steps you can take.
If you're uploading images to a website still using HEIC or even JPG, you're leaving significant performance on the table. Smaller images mean faster page loads, which directly improves your Core Web Vitals scores — particularly Largest Contentful Paint (LCP), a confirmed Google ranking signal.
WebP vs JPG vs PNG — Which is Best for Websites?
| Format | Typical file size | Quality | Browser support | Best for |
|---|---|---|---|---|
| WebP | Smallest | Excellent | 97%+ (all modern) | Websites, page speed |
| JPG | Medium | Very good | 100% (universal) | Email, social media, print |
| PNG | Large | Lossless | 100% (universal) | Logos, graphics, editing |
| HEIC | Very small | Excellent | Limited (Apple only) | iPhone storage |
| AVIF | Smallest | Excellent | ~90% | Cutting-edge web |
For website use, WebP is the clear winner — it combines the file size advantages of HEIC with near-universal browser compatibility. The only reason to use JPG over WebP on a website today is legacy compatibility with very old browsers, which represent less than 3% of global traffic.
How WebP Improves Your SEO
Converting your website images from HEIC or JPG to WebP can meaningfully improve your search rankings through the following chain:
- Smaller files → faster pages — a 35% reduction in image file size directly reduces page load time, especially on mobile connections
- Faster pages → better LCP — Largest Contentful Paint measures how fast your main content loads. Images are usually the LCP element. WebP images load faster, improving your LCP score
- Better Core Web Vitals → higher rankings — Google uses Core Web Vitals as a ranking signal. Improved LCP can push pages higher in search results
- Lower bounce rate — faster pages keep visitors on-site longer, sending positive engagement signals to Google
- Better mobile experience — most website traffic is mobile, where connections are slower. WebP makes the biggest difference on mobile
Understanding the Quality Slider for WebP
WebP quality works similarly to JPG — a percentage controls how much image data is preserved vs discarded to reduce file size:
- 80–85% (recommended for web) — the optimal balance for most website images. Visually indistinguishable from the original at significantly smaller file sizes. This is Google's own recommended range for WebP on the web.
- 90%+ — for high-detail photography, product shots, or portfolio images where visual quality is the priority.
- 70–78% — for thumbnails, background images, or decorative elements where the smallest possible file size matters most.
Unlike JPG, WebP also supports lossless compression (100% quality) and transparency — making it more versatile than JPG for web use.
Does WebP Work in All Browsers?
Yes. WebP is now supported by all major browsers — Chrome, Safari (since version 14), Firefox, Edge, and Opera. Global WebP browser support exceeds 97% as of 2025. The remaining browsers are predominantly very old versions that represent negligible traffic. It's completely safe to use WebP as your primary image format on any modern website.
WordPress 5.8+ automatically converts uploaded images to WebP if your server supports it. Shopify serves WebP natively. Most modern CDNs and image hosts also serve WebP automatically when supported by the visitor's browser.

Frequently Asked Questions
Why convert HEIC to WebP instead of JPG?
WebP produces files 25–35% smaller than JPG at the same visual quality. For website images, this means faster page loads, better Core Web Vitals scores, and improved SEO. For offline sharing or email, JPG is still the more universally compatible choice. For web publishing, WebP is the better option.
Is this HEIC to WebP converter free?
Yes, completely free. No signup, no watermarks, no file size limit, no restrictions on conversions. Runs entirely in your browser — we never see your files and there are no server costs to pass on.
Are my HEIC photos uploaded to a server?
No. Conversion runs entirely in your browser using JavaScript. Your files never leave your device and are never sent to any server. This is a technical design decision — it also means conversion is instant because there's no upload time.
Does WebP work in all browsers?
Yes. WebP is supported by all modern browsers — Chrome, Safari (v14+), Firefox, Edge, and Opera. Global browser support exceeds 97% as of 2025. It's safe to use WebP as your primary image format on any modern website.
Can I convert multiple HEIC files to WebP at once?
Yes. Drop as many HEIC files as you want at once. The tool converts every file in your browser and lets you download individually or use "Download All" to get every WebP file at once. No file count limits, no size limits.
Does WebP improve SEO?
Yes, indirectly but meaningfully. WebP images are smaller, pages load faster, and page speed is a confirmed Google ranking factor. Faster loading improves Largest Contentful Paint (LCP), a Core Web Vitals metric that Google uses in its ranking algorithm. Switching to WebP is one of the highest-ROI technical SEO improvements for image-heavy sites.
What quality setting should I use for WebP?
80–85% is the recommended sweet spot for most web images — visually identical to the original at significantly smaller file sizes. Use 90%+ for high-detail photography or product shots where quality is critical. Use 70–75% for thumbnails or background images where smallest file size is the priority.
Does this HEIC to WebP converter work on iPhone?
Yes. Works on Safari on iPhone and iPad, Chrome on Android, and all desktop browsers. No app download required on any device.
