HEIC for the source photo, WebP for the web
For HEIC vs WebP, keep HEIC as the source photo and create WebP when the image is being prepared for a website that supports it.
Photo storage versus web delivery
HEIC is commonly used for efficient photo capture and storage on modern devices. WebP is an image format designed for web use and supports both lossy and lossless compression.
WebP also supports transparency and animation, which makes it useful for many web assets beyond ordinary photos.
HEIC vs WebP at a glance
A practical comparison for source photos and web images.
| Decision point | HEIC | WebP |
|---|---|---|
| Typical use | Phone photos and HEIF-based source-image storage. | Website images and browser delivery. |
| Compression | Commonly HEVC-based inside HEIF. | Supports lossy and lossless compression. |
| Transparency / animation | HEIF can carry auxiliary images and sequences depending on the file. | WebP supports alpha transparency and animation. |
| When to choose it | Keep it when it is the original and your photo workflow supports HEIC. | Use it when publishing to a website or app that supports WebP. |
File size depends on the encoder and settings
Neither format has one fixed size advantage. For a website, compare WebP output made from the same source at acceptable visual quality and choose settings that fit your performance needs.
Which should you use?
Keep HEIC as the original photo when it works in your library and editing apps. Create WebP for web publishing when the site supports it.
If the recipient is a person or an unknown application rather than a website, JPG may be a more predictable converted format.
Preview a HEIC file before deciding. For a website image, convert HEIC to WebP; when JPEG is required, make a JPG copy.
Why WebP is common on websites
WebP is broadly supported by modern browsers and was designed for web image delivery. HEIC is more closely associated with device-origin photo workflows and is not a normal universal web-image choice.
Simple rule of thumb
For HEIC vs WebP, keep HEIC for the original photo and use WebP for a website that supports it.
