Convert HEIC to WebP
Free, private, and instant — your files never leave your device.
HEIC is Apple's space-efficient iPhone photo format, but its poor cross-platform support makes it impractical for web use — no major web platform accepts HEIC as an upload format, and no browser renders it natively (except Safari). WebP is the opposite: supported in all major browsers since 2020 and accepted by virtually every modern CMS, web app, and image pipeline. Converting HEIC to WebP is the best path when you want to use an iPhone photo on a website or web app: you get a compact, modern format with full browser compatibility, full alpha-channel support, and no codec licensing issues.

Frequently Asked Questions
Why use WebP instead of JPEG for web delivery of iPhone photos?
WebP typically produces files 25–34% smaller than JPEG at equivalent visual quality. If your audience is on modern browsers (all major browsers since 2020), WebP is the better choice. Use a JPEG fallback via the HTML <picture> element if you need to support legacy browsers.
Does HEIC support transparency? Does WebP preserve it?
Standard iPhone camera HEIC photos do not use transparency. WebP supports full alpha-channel transparency, but since the source HEIC is opaque, the output WebP will also be opaque.
How does the WebP file size compare to the original HEIC?
HEIC is extremely efficient — comparable to or smaller than WebP. The WebP will typically be similar in size or slightly larger than the HEIC. The value of converting is compatibility, not compression: WebP works on the web; HEIC does not.
Can I use the converted WebP on all websites?
On any platform that accepts image uploads (social media, CMSes, web apps, CDNs), WebP is supported. If a platform specifically requires JPEG or PNG, use the HEIC-to-JPG or HEIC-to-PNG converter instead.
