# Convert HEIC to AVIF.

> iPhone HEIC to web-ready AVIF — converted on your device.

Convert iPhone HEIC photos to AVIF entirely in your browser — **decoded and re-encoded on your device, never uploaded**. HEIC and AVIF are equally modern, but only one of them works on the web: AVIF displays in every current browser, while HEIC stays locked to Apple software. Batch a whole album and download the ZIP.

**No uploads · No ads · Free & open source.**

## How it works

1. Drop files anywhere on the page, click to browse, or paste with Ctrl/⌘ + V.
2. Pick a quality or preset — or set an exact target size and let the tool find it.
3. Compress, compare before/after, and download — individually or as a ZIP.

## Two modern formats, one web-ready

Both formats compress photos far tighter than JPG — that part is a tie. The difference is reach: browsers never adopted HEIC, so an iPhone photo cannot be embedded on a website as-is, while AVIF can, at essentially the same size. For older apps and upload forms, [HEIC to JPG](https://compress-pro.com/heic-to-jpg) remains the safe exit; for anything headed to the web, AVIF is the better one, and [Compress HEIC](https://compress-pro.com/compress-heic) covers the keep-it-HEIC case.

## Metadata is stripped

The AVIF is written clean: EXIF, GPS location and camera details do not carry over. For photos headed to the public web that is the safer default — location data in particular has no business on a website. Rotation is applied during decode, so photos come out upright.

## Frequently asked questions

### Why AVIF instead of JPG?

Size at quality: AVIF stores the same photo in roughly half the bytes of an equivalent JPG. Choose JPG only when the file must open in older software — every current browser displays AVIF fine.

### Does GPS location stay in the photo?

No — AVIF output is written without EXIF or GPS metadata. What your camera recorded stays on your device, in the original HEIC.

### What can open the AVIF afterwards?

Browsers universally — Chrome, Edge, Firefox, and Safari from 16.1. Older desktop viewers and some upload forms may refuse it; convert those photos to JPG instead.

### Is it private?

Yes. The conversion happens entirely on your device — the image is read, re-encoded and saved without ever touching a network. There is no server-side queue, no temporary copy in some bucket, nothing to expire or leak. Want proof? Run one file through, switch your connection off, and run another — it still works.
