About the HEIC to AVIF Converter
Convert HEIC to AVIF online for free, with no account and no watermark. Windows PCs, many Android phones and most upload portals cannot open HEIC photos, so switching to AVIF is the quickest way to get the smallest next-generation web images for the smallest possible website images and Core Web Vitals optimisation.
The converter decodes your HEIC with your browser's own image engine and writes the AVIF with a small open-source AVIF encoder, so quality settings are applied precisely. Because everything happens on your own device, your photos are never uploaded, stored or seen by anyone else, which makes it safe for ID photos, Aadhaar or PAN scans and personal pictures.
What to expect: AVIF is compressed, and the quality slider lets you trade file size against detail; camera metadata such as GPS location is removed because the image is re-encoded.
How to use the HEIC to AVIF Converter
- Click "Choose files" or drag your HEIC photos onto the box. You can add several at once.
- Adjust the AVIF quality slider (85 is a good default) and, if you like, set a maximum width to resize.
- Press "Convert to AVIF". The conversion runs on your device and shows its progress.
- Download each AVIF file, or use "Download all (ZIP)" when you converted several.
- Open the result in Chrome or Edge to check it; your original HEIC is never changed.
Tips & benchmarks
- AVIF encoding is slower than JPG; a quality of 50–65 already looks excellent and gives tiny files.
- iPhone users can avoid HEIC altogether: Settings → Camera → Formats → Most Compatible makes the camera save JPG photos.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the AVIF to a website or government portal.
