## About

Turn iPhone HEIC photos into WebP — typically a quarter smaller than JPG at the same look — decoded locally in your browser, nothing uploaded.

## Quick answer

How do I convert HEIC to WebP? Add your .heic or .heif file, set the quality (85% suits most photos), and download the WebP. The decoder runs on your device — the photo is never uploaded.

## How to convert HEIC to WebP

1. **Add your HEIC or HEIF file** — drag it in or browse; the decoder loads once, then works offline.
2. **Set the WebP quality** — 85% suits most photos and lands far smaller than the JPG equivalent.
3. **Download the WebP** — preview first, then save. Your original HEIC stays untouched.

## Why WebP for iPhone photos

- **Size** — WebP typically runs 25–35% smaller than JPG at the same visual quality; for sites and modern apps that's free savings on every image
- **Compatibility** — every current browser displays WebP, and Windows 11, macOS, and major social platforms accept it
- **When to pick JPG instead** — old desktop software, some print shops, and a few upload portals still expect JPG; [HEIC to JPG](https://toolpantry.app/heic-to-jpg.html) covers those

## Good to know

HEIC already compresses well, so converting isn't about shrinking your library — it's about *compatibility* (many apps can't open HEIC at all) with WebP keeping the smallest footprint while doing it. Need lossless output for editing? [HEIC to PNG](https://toolpantry.app/heic-to-png.html). Want the smallest file a strict form will accept? Run the result through the [target-size compressor](https://toolpantry.app/compress-image-to-100kb.html). Building a site? [JPG to WebP](https://toolpantry.app/jpg-to-webp.html) handles the rest of your images the same way.

## Notes

The decoder (~1.3 MB) downloads once per visit and everything after that happens locally. Burst photos and Live Photos contain multiple images — this tool converts the primary one.

## FAQ

**Why convert HEIC to WebP instead of JPG?**

WebP is typically 25–35% smaller than JPG at the same visual quality, and every modern browser displays it. For websites and modern apps, WebP is the lighter choice; keep JPG for older software and print shops.

**Is my photo uploaded during conversion?**

No. The HEIC decoder is downloaded to your browser once and runs locally — the photo itself never leaves your device.

**Which apps can open WebP?**

All current browsers (Chrome, Safari, Edge, Firefox), Windows 11 photo tools, macOS Preview, and most design and social tools. Very old software may not — convert to JPG in that case.
