Convert iPhone HEIC Photos to WEBP Without Uploading Them Anywhere
If you own an iPhone, you probably have thousands of HEIC files without really noticing. Since iOS 11, Apple has stored photos in HEIC, a container that uses the HEVC codec to keep files roughly half the size of an equivalent JPG. Inside the Apple ecosystem that works beautifully. Outside it, HEIC is friction: most browsers cannot display it, Windows needs an extension from the store, Android handling is inconsistent, and a surprising number of web platforms reject the format outright. Converting is also the only practical option when a photo has to reach someone on a completely different platform.
WEBP is the natural destination when the photo is headed for the web. Created by Google and supported by every current browser, it typically produces files 25 to 35 percent smaller than a comparable JPG, supports transparency, and is the format Google’s own page-speed guidance encourages. This tool reads your HEIC photo, decodes it locally in the browser through a lightweight decoder that loads only when a HEIC file is actually added, and encodes the result as WEBP at the quality you select. Because decoding happens on your own device, even a large iPhone export stays private, and there is no upload queue to wait on.
People who need this usually have a destination in mind. Bloggers and marketers publish iPhone photos on sites where page weight affects Core Web Vitals and search rankings. Sellers prepare product shots for storefronts that need images loading quickly on mobile. Developers normalise a mixed library of Apple photos into one web-friendly format before feeding a content pipeline. Volume matters too, because a single holiday export can hold hundreds of files at once.
A few honest limits are worth stating. HEIC can hold more than a still image — Live Photo motion, depth maps, and bursts — and a single still WEBP keeps none of that, so you get the main frame. Camera metadata support in WEBP is limited, so some EXIF fields may not carry across. Within those limits the job is simple: add one photo or a whole export, choose WEBP, set quality between 10 and 100, optionally cap the width, and download results individually or as a ZIP.
Everything runs in your browser, so private photos never leave your device, and there is no account to create, no watermark, and no daily quota. Add your HEIC files and convert them in a few seconds.
Local HEIC Decoding
HEIC files are decoded in your browser by a lightweight decoder, never on a server.

Keeps Transparency
Alpha data survives the conversion, which matters for cutouts and product shots.
Batch Conversion
Turn a whole iPhone export into WEBP files and download them as one ZIP.
Quality Control
Move the slider between 10 and 100 to pick your own size and clarity balance.
No Account Needed
Convert as many photos as you like without signing up or installing an app.
FAQ
Frequently Asked Questions
HEIC is the photo format Apple has used since iOS 11. It stores images with the HEVC codec, keeping quality high at roughly half the file size of a comparable JPG, but support outside Apple devices is limited.
WEBP is usually 25 to 35 percent smaller than a JPG at similar quality and is supported by every current browser, so it is the better target when photos are going onto a website or storefront.
No. The tool loads a small decoder in the browser only when you add a HEIC file, so there is no app, plugin, or system extension to install on Windows, Android, or macOS.
No. Decoding and WEBP encoding both happen locally in your browser, so your photos stay on your device. Nothing is uploaded, stored, or shared at any point in the process.
Yes. Select a whole batch of HEIC or HEIF photos, convert them in one pass, and download the finished WEBP files individually or together in a single ZIP archive. Each file keeps its original name with the extension changed.
No. A still WEBP holds one image, so Live Photo motion, depth maps, and burst sequences are not carried over. You get the main frame of the photo as a standard WEBP file.
Not always. HEIC is already very efficient, so a WEBP at high quality can end up similar in size or slightly larger. The gain is compatibility, since WEBP renders in every current browser.
Yes, when the source contains alpha data. Both formats support transparency, so cut-outs and transparent product images keep their see-through background. Standard iPhone camera photos have no transparency, so most files are unaffected either way.
Yes. Any modern browser on Windows, Android, macOS, or Linux can run the converter, which is useful precisely because those platforms handle HEIC poorly or not at all. There is no need to install Apple software or a system extension first.
There is no daily quota, watermark, or account requirement. The only practical ceiling is your own device memory, since photos are decoded and encoded locally, and very large batches are simply processed one file at a time.
