Convert HEIC to WebP for a faster website
HEIC to WebP conversion turns heavy iPhone photos into light, modern images that are made for the web. HEIC is efficient on your phone, but browsers, website builders and content management systems don’t display it. JPG works everywhere, yet the files are larger than they need to be. WebP sits in the sweet spot: it is supported by all current browsers and is often 25–35 % smaller than a JPG of similar quality.
This HEIC to WebP converter runs completely inside your browser. A WebAssembly build of libheif decodes each photo on your own device, so nothing is uploaded and there is no account, no watermark and no limit on the number or size of files.
Why WebP is a good fit for websites and WordPress
Images are usually the heaviest part of a web page. Every extra megabyte slows down loading, especially on mobile connections, and search engines pay attention to page speed through Core Web Vitals. Converting iPhone photos to WebP before you upload them is one of the simplest ways to keep a site fast.
- Blogs and WordPress sites – product shots, recipe photos and travel pictures load faster and use less storage on your hosting.
- Online shops – lighter product galleries make category pages and product pages feel snappier.
- Portfolios and landing pages – large hero images stay sharp without weighing down the first screen.
- Documentation and help pages – photos of devices or setups stay readable and quick to load.
HEIC to WebP: quality and size settings
The converter starts with a quality of 85, a balanced setting for web images: photos stay crisp while the files remain small. You can lower it when speed matters most, or raise it for images that visitors will zoom into.
The Size option lets you shrink the photo at the same time. Choose “Original size” or a maximum of 3840, 2560, 1920, 1280 or 800 px on the long side. Proportions are kept and photos are never enlarged. A 12-megapixel iPhone photo is around 4000 px wide, far more than most layouts display, so 1920 px is a sensible choice for full-width images and 1280 px for images inside an article.
| Format | Typical use | File size |
|---|---|---|
| HEIC | Storing photos on iPhone | Small, but not shown by browsers |
| JPG | Sharing, printing, e-mail | Medium |
| WebP | Websites, blogs, WordPress | Often 25–35 % smaller than JPG |
| PNG | Editing, design, lossless copies | Large |
How to convert iPhone photos to WebP
On Windows, Mac, Linux or ChromeOS: open this page in Chrome, Edge or Firefox, choose WebP under “Convert to” and drag your HEIC files onto the drop zone. Use “Choose a folder” to convert a whole folder, then click “Download all (ZIP)”.
On Android: if you received iPhone photos through WhatsApp, e-mail or a cloud drive, open this page in Chrome, tap “Choose photos” and save the WebP versions to your phone.
On iPhone and iPad: Apple browsers can’t create WebP files, so WebP export isn’t available in Safari or on iPhone and iPad – the converter tells you when that’s the case. Choose JPG instead, or transfer the photos to a computer and convert them there in Chrome, Edge or Firefox.

Colours, metadata and privacy
WebP keeps the photo’s full resolution (unless you choose a smaller size), and orientation is applied correctly so portrait shots don’t appear sideways. Photos you publish online should not reveal where they were taken: the GPS location in iPhone photos can point to your home. If you want to be sure your images are clean before uploading them, use our tool to remove the location from a photo.
When another format is better
WebP is ideal for the web, but not for every task. If a print shop, an older program or an e-mail recipient needs something universal, use the HEIC to JPG converter. If you simply want a smaller JPG for e-mail or messaging, compress HEIC photos with a size preset. And for editing or design work where every pixel counts, choose the lossless HEIC to PNG converter.
