Convert HEIC to WebP

WebP is the pick when the photo is headed for a website: it compresses photographs harder than JPEG at similar visual quality, and every mainstream browser has displayed WebP natively for years now (unlike HEIC, which never got that support). If you’re converting iPhone photos to put on a blog, a product listing or your own site, this preset gives you the smallest usable files.

The conversion happens entirely on your device — the HEIC is decoded by a WebAssembly build of libheif running in your browser, redrawn, and re-encoded as WebP. Nothing is uploaded, which you can verify in your browser’s Network tab while it runs.

How it works

  1. Open this page — the converter is already set for “Convert HEIC to WebP”.
  2. Drop your photos into the box, click to browse, or paste with Ctrl+V. Batches are fine.
  3. Your browser decodes and re-encodes each photo on your own device — nothing is uploaded.
  4. Check the preview and file size on each result card, then download.

Where WebP is the right answer — and where it isn’t

Right: images embedded in web pages (smaller files, faster loads, better Core Web Vitals), photos for online listings that accept it, and archives where you want JPEG-class quality in fewer bytes.

Wrong: anywhere a human will double-click the file on an older desktop. Windows and macOS handle WebP far better than they handle HEIC, but plenty of older photo software, printing kiosks and upload forms still expect JPG. When in doubt about the destination, JPG remains the format that never raises questions.

Picking a quality setting

The slider on this page is the WebP encoder quality. 90% is visually indistinguishable from the source for nearly all photos; 80% is a good web default that shaves files noticeably; below 70% fine texture (hair, foliage, fabric) starts to soften. The result card shows the exact output size for each photo, so you can re-drop the same file at a different setting and compare in seconds — there’s no upload round-trip to wait for.

Frequently asked questions

Is WebP smaller than JPG for the same quality?

Usually, yes — for photographs WebP typically lands noticeably under an equivalent-quality JPEG, which is why websites serve it. Exact savings depend on the image; the result card shows your real numbers.

Will a WebP file open on Windows and Mac?

Current versions of Windows Photos, macOS Preview and every mainstream browser open WebP. Older photo editors and some upload forms still refuse it — if the file is destined for unknown software, JPG is the safer choice.

Can I convert a whole batch of HEICs to WebP at once?

Yes — drop as many as you like; they convert one after another on your device and a “Download all” button appears when more than one result is ready. There’s no file cap or daily quota.
