Convert HEIC to WebP
Drop your iPhone HEIC photos and download WebP copies that stay small but open everywhere. The HEIC is decoded by the libheif WebAssembly engine and re-encoded as WebP entirely inside your browser, so your pictures never reach a server.
How to convert HEIC to WebP
- Drop one or many HEIC files into the box below.
- libheif decodes each frame and a Canvas re-encodes it as WebP, all inside your browser.
- Download the WebP copies individually or as a batch.
Why convert HEIC to WebP?
HEIC keeps iPhone photos small but almost nothing outside the Apple ecosystem can open it, while WebP is both compact and supported by every modern browser, CMS and image host since 2020. Converting HEIC to WebP is the right move when you want to publish iPhone photos to a website, a blog, an online store or a marketing page without paying the bandwidth tax of JPG or PNG — a WebP is usually 25–35% smaller than the equivalent JPG at the same visible quality. Unlike a HEIC, the WebP will display inline in Chrome, Edge, Firefox, Safari (since iOS 14) and virtually every uploader, so you avoid the broken-image problem that HEIC causes on the open web. Keep the original HEIC as your master if you may need to re-export later, since WebP is a one-way lossy step.
How we compare
The closest peer to this tool is Google's Squoosh, which also runs fully in your browser. Squoosh focuses on compression for the modern web and does not handle HEIC or batch conversion. Cloudconvert and Convertio cover more formats but upload your files to their servers and meter usage.

Frequently asked questions
Are my photos uploaded to a server?+
No. The HEIC decoder and WebP encoder both run inside your browser tab. No image data ever leaves your device.
Why convert HEIC to WebP instead of JPG?+
WebP is roughly 25–35% smaller than JPG at the same quality, which matters when you are publishing photos to the web. If you only need broad compatibility for email or older software, HEIC to JPG is the safer choice.
Will the quality drop?+
WebP is lossy by default, but at the encoder's high-quality setting the difference is invisible on photographs. The file is far smaller than a JPG or PNG of equal quality.
Can I convert many HEIC files at once?+
Yes. Drop a whole folder of iPhone exports and they are processed one after another. Large batches simply take a little longer.
Does WebP work on iPhone and older browsers?+
WebP is supported in every modern browser including iPhone Safari since iOS 14. For software older than 2020, convert to JPG instead.
Does it work offline?+
Yes. After your first visit the decoder is cached, so the converter keeps working with no internet connection.
