Tip: add several files at once to convert them in one go and download them as a ZIP.
About converting HEIC to WebP
HEIC (.heic) files can be converted to WebP entirely in your browser — no software to install, no file upload, and no account required. The conversion runs on libheif (the reference HEIC decoder) compiled to WebAssembly, plus the browser's Canvas API directly on your device.
Technical comparison
| HEIC | WebP | |
|---|---|---|
| Category | image | image |
| Compression type | Lossy (HEVC intra-frame) | Lossy or lossless (configurable) |
| Typical file size | Small — roughly 40–50% smaller than an equivalent JPEG | Small — often 25–35% smaller than an equivalent JPEG |
| Transparency support | Yes | Yes (full alpha channel) |
How to convert HEIC to WebP privately
Every step below runs on libheif (the reference HEIC decoder) compiled to WebAssembly, plus the browser's Canvas API inside this browser tab. Your .heic file is never uploaded to a server — there's no network request carrying it anywhere.
Add your HEIC file
Drag and drop, or click to select, a file (.heic). It's read straight from disk into browser memory — no upload step exists.
Convert locally
FreePrivateConvert converts it to WebP using libheif (the reference HEIC decoder) compiled to WebAssembly, plus the browser's Canvas API, entirely within this browser tab.
Download the result
Save your converted .webp file. It only ever existed in this tab's memory — closing the tab without downloading discards it completely.
Convert HEIC to WebP with ffmpeg (command line)
Prefer the terminal? This page uses libheif, the reference HEIC decoder, running in your browser; the equivalent ffmpeg command is:
ffmpeg -i input.heic -c:v libwebp output.webp- -i input.heic
- Your HEIC file.
- -c:v libwebp
- Encode the image as WebP.
- output.webp
- The WebP file to create. ffmpeg picks the container from this extension.
Desktop ffmpeg only reads HEIC in recent releases (7.1 and newer), and iPhone photos can still fail on some builds.
Don't have ffmpeg installed? You don't need it: use the converter at the top of this page. It runs this conversion on your own device, and your file is never uploaded.
FAQ
- Is my file uploaded anywhere?
- No. Your file is read and processed inside this browser tab and never leaves your device. You can confirm it in your browser's developer tools: the Network tab shows no upload.
- Does converting HEIC to WebP reduce quality?
- WebP here is lossy at 92% quality: usually indistinguishable from the original for photos while noticeably smaller. Transparency is kept.
- Is there a file size limit?
- Yes: 500MB per file. There's no account and no limit on how many files you convert.
- What's the difference between HEIC and WebP?
- HEIC (High Efficiency Image Format) and WebP store data differently. HEIC: lossy (HEVC intra-frame). WebP: lossy or lossless (configurable). WebP is Google's modern image format, supporting both lossy and lossless compression plus alpha transparency and animation in one file type.
- Why convert HEIC to WebP?
- Common uses for WebP: Web page hero and background images; Responsive <picture>/srcset fallbacks; Replacing animated GIFs to cut page weight. Lossy WebP typically produces 25–35% smaller files than JPEG at equivalent visual quality.
- What MIME type does a .webp file use?
- image/webp, the standard type for WebP.
- What is the ffmpeg command to convert HEIC to WebP?
- Run: ffmpeg -i input.heic -c:v libwebp output.webp. This page does the same conversion with libheif, the reference HEIC decoder, running in your browser, so you don't need to install ffmpeg. Desktop ffmpeg only reads HEIC in recent releases (7.1 and newer), and iPhone photos can still fail on some builds.
