¶HEIC to AVIF Converter

Convert HEIC photos from iPhone and other Apple devices to AVIF — the open, efficient image format supported across Chrome, Firefox, and Safari 16+. AVIF offers comparable compression to HEIC but works everywhere. All processing happens locally in your browser; your photos are never uploaded.

¶How to Use

1. Upload your HEIC or HEIF files — drag and drop or click to select one or more photos.
2. Choose a quality level — High (85%) is recommended for general use.
3. Convert — click Convert All or convert files individually.
4. Download — save individual AVIF files or click Download All as ZIP.

¶HEIC vs AVIF

Both HEIC and AVIF are modern, high-efficiency image formats, but they serve different ecosystems:

• HEIC is Apple's format, based on the HEVC video codec. It is the default on iPhones (iOS 11+) and Macs.
• AVIF is an open format based on the AV1 codec, supported across Chrome, Firefox, Edge, and Safari 16+.

Converting HEIC to AVIF gives you a file that works natively in any modern browser without special plugins, while maintaining comparable quality and file size.

¶Browser Requirements

This tool uses two technologies: heic2any to decode HEIC files, and the browser's Canvas API to encode AVIF. AVIF encoding requires Chrome 93+ or Firefox 93+. Safari does not support AVIF encoding via the Canvas API, so this tool requires Chrome or Firefox.

¶Frequently Asked Questions

Why does conversion take a moment?
HEIC decoding is computationally intensive. The heic2any library processes each file in JavaScript, which takes a second or two per image depending on file size and your device speed.

Will my photo quality be preserved?
At High (85%) quality, the output will be visually indistinguishable from the original for most photos. High-resolution photos from recent iPhones contain a lot of detail; use Maximum (95%) if you want to be certain.

Are my photos uploaded to a server?
No. Everything runs entirely in your browser. Your photos never leave your device.

Does this preserve EXIF metadata?
No. The conversion pipeline decodes to a canvas and re-encodes, which strips EXIF metadata including GPS location and camera settings.
