Why use WebP for photos on a website?
WebP is an image format Google created for the web. Google’s own comparison reports that lossy WebP files are 25–34% smaller than comparable JPEGs at the same quality. Smaller images download faster, which helps pages load quickly – something search engines take into account through Core Web Vitals.
iPhone photos are a common source of oversized web images: a straight-from-the-camera photo is often several megabytes, far more than a blog or shop page needs. Converting to WebP and scaling down can cut that dramatically.
How to convert HEIC to WebP
- Add your HEIC photos to the box above.
- Choose WebP. Set quality to about 80% for web photos.
- Set Max size to 1600 or 2048 px for most page layouts.
- Press Convert all and download the files or a ZIP.
Where WebP works – and where it does not
| Where | WebP support |
|---|---|
| Current Chrome, Edge, Firefox, Safari | Displays WebP |
| CMS platforms and website builders | Most current ones accept WebP uploads |
| Email clients | Mixed – use JPG for email |
| Print shops, older editors, some marketplaces | Often not accepted – use JPG |
When a photo has to work everywhere, keep a JPG copy alongside the WebP.
Serving WebP with a JPG fallback
If you run a website, the HTML <picture> element lets browsers choose the best format they support:
<picture>
<source srcset="photo.webp" type="image/webp">
<img src="photo.jpg" alt="Describe the photo" width="1600" height="1067">
</picture>Picking a WebP quality
- 75–85% is a common range for web photos.
- Below 70% is fine for thumbnails but shows artefacts on large images.
- Above 90% rarely looks different but makes files bigger.
This converter creates lossy WebP. For a lossless copy, use PNG.

Frequently asked questions
Quick answers about HEIC files, privacy and conversion.
Why convert HEIC to WebP?
WebP was designed for the web. Google reports that WebP images are 25–34% smaller than comparable JPEGs at the same quality, which helps pages load faster.
Which browsers can save WebP files?
Chrome, Edge and Firefox can encode WebP. Some browsers, notably Safari, may not be able to. If your browser cannot, the converter tells you instead of producing a mislabelled file – switch browser or choose JPG or PNG.
Can every website and app open WebP?
All current major browsers can display WebP. Some older apps, email clients, print services and image editors still cannot, so keep a JPG copy if the file has to work everywhere.
What WebP quality should I choose for the web?
A quality of 75–85% is a common range for web photos, and a maximum size of 1600–2048 pixels on the long side is enough for most layouts.
Does this create lossy or lossless WebP?
Lossy WebP, using the quality slider. If you need a lossless copy, choose PNG instead.
Will WebP help my SEO?
Smaller images can make pages load faster, and page speed is one of the signals Google looks at. Image size alone will not rank a page, but it removes a common performance problem.
