Convert HEIC to WebP

Turn your HEIC photos into WebP to publish them on a website: small files, readable by every browser.

Drop your HEIC files here

Or choose them, or paste an image (Ctrl + V or ⌘ + V).

Up to 20 files of 50 MB each (10 files of 30 MB on mobile).

The lower the quality, the smaller the file.

Longest side, proportions kept. Never enlarged.

Metadata (GPS location, camera, date) is always removed from the converted file.

    100% local processing, nothing is uploaded

    How does it work?

    HEIC (High Efficiency Image Container)

    HEIC has been the default photo format of iPhones and iPads since iOS 11 (“High Efficiency” option). Based on HEVC compression, it produces photos about half the size of JPG at equal quality. But Windows only opens it with extensions to install, Chrome and Firefox do not display it, and many websites reject HEIC files.

    WebP

    WebP, created by Google, was designed for the web. It offers lossy or lossless compression, transparency and animation, with files 25 to 35% smaller than a JPG of comparable quality. Every current browser reads it, but some older software (viewers, office programs, printing services) cannot open it yet.

    HEIC or WebP: which format should you choose?

    Keep HEIC on your iPhone: it is an excellent storage format, but the Chrome and Firefox browsers cannot display it.

    WebP is the right choice for publishing your photos on the web: every current browser reads it, and it stays almost as light as HEIC. For office software or a printing service, prefer JPG, which is more universal.

    How does the conversion work?

    1. Drop your HEIC files in the area provided, choose them or paste an image: several files at once if you like.
    2. Adjust the options if needed: they apply to every file in the list, which are converted again automatically.
    3. Download each WebP file, or all of them at once in a ZIP archive.

    The conversion takes place in your browser. For your information:

    • The real format of each file is checked from its content, not its extension.
    • HEIC photos are decoded by libheif, a free library running in your browser (WebAssembly), downloaded only once with the first file.
    • If your browser cannot create WebP itself (Safari, for example), a free WebAssembly encoder takes over automatically.
    • The photo’s orientation is applied: the converted image displays the right way up everywhere.

    Examples

    Illustrating a blog post with iPhone photos

    You import 8 HEIC photos of about 2.5 MB. With a maximum size of 1,280 px and quality 80, each becomes a WebP of about 150 to 250 KB: your page loads fast, even on mobile.

    Stocking an online store

    Your product photos, taken with an iPhone (4,032 × 3,024 px), are converted to WebP at 1,920 px and quality 85: about 350 KB per image instead of 2 MB, with no visible difference on the product page.

    Frequently asked questions

    Why not publish my HEIC photos directly on my website?

    Because only Safari and recent Apple devices can display HEIC. On Chrome, Edge or Firefox, your visitors would see a missing image. WebP, on the other hand, displays in every current browser.

    Does WordPress accept WebP?

    Yes, WordPress has accepted WebP images in its media library since version 5.8 (2021). Most other CMSs and online store platforms accept them too.

    What quality should I choose for the web?

    The default quality of 80 suits most photos. Go down towards 70 for thumbnails, up towards 90 for a large featured photo.

    Why is the conversion slower on iPhone?

    Safari cannot encode WebP itself: a WebAssembly encoder takes over, which is a little slower. On iPhone, very large photos are also scaled down automatically to stay under Safari’s memory limit, and you are told when that happens.

    Are my HEIC files uploaded to a server?

    No. The conversion runs entirely in your browser, on your device: your files are never uploaded, stored or viewed by anyone. You can check this in the “Network” tab of your browser’s developer tools: no file appears there. Metadata (GPS location, camera, date) is also removed from the converted file.
