Convert HEIC to WebP
Putting iPhone photos on a website? Skip the bloated middle step and convert HEIC straight to compact WebP here — privately, in your browser.
HEIC vs WebP: what changes
Your iPhone shoots in HEIC, which nothing on the web can display directly. The usual fix is to convert to JPG, but if the destination is a website, WebP is the smarter target: it loads faster and weighs less at the same quality.
Converting HEIC → WebP in one step skips the heavier JPG or PNG stage entirely, giving you a web-ready image that’s typically 25–35% smaller than the JPG equivalent. Every modern browser supports WebP, so it’s ready to ship. The HEIC decoder loads automatically the first time, and nothing is uploaded — your photos stay on your device.

Why convert in your browser
Nothing is uploaded
Every byte is decoded and re-encoded on your own machine using Canvas and WebAssembly. Your images never touch a server, so there is no upload bar, no queue, and no copy of your file sitting in someone else’s bucket.
Works offline
After the first load the converter is cached. Open it on a plane, on hotel Wi-Fi, or with the cable unplugged and it still runs at your CPU’s full speed.
Frequently asked questions
Why WebP instead of JPG for the web?
WebP usually produces a smaller file than JPG at the same quality, so pages load faster. For a website it’s the better target; for email or universal compatibility, JPG is still the safe choice.
Will I lose photo quality?
HEIC is already compressed by the camera. Converting to WebP at quality 80+ keeps the result visually identical for almost any web use, while keeping the file small.
Are my photos uploaded?
No. Decoding and encoding happen with WebAssembly inside your browser. Your photos never leave your computer or phone.
Does this work on iPhone and iPad?
Yes — it runs in Safari or Chrome on iOS, so you can convert straight from your phone without an app.
