HEIC (High Efficiency Image Container) uses lossy or lossless encoding and is best for Apple device photos — iPhone and Mac default format with excellent compression efficiency. AVIF (AV1 Image File Format) uses lossy or lossless encoding and excels at next-gen web images — royalty-free format with better compression than WebP and JPEG. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
AVIF typically produces files 30-50% smaller than JPG at the same visual quality. If you are optimizing for web performance, AVIF gives you faster page loads without sacrificing image clarity.
AVIF is supported in Chrome 85+, Firefox 93+, and Safari 16.4+. Older browsers like Internet Explorer will not display it. Check your audience's browser support before using AVIF on production sites.
HEIC and AVIF both use modern compression, so the conversion introduces minimal quality loss. For most photos the difference is imperceptible. Choose lossless mode if you need pixel-perfect results.
This tool converts one image at a time. Upload and convert each HEIC file individually — there is no limit on the number of conversions you can run.
The converter preserves the color profile from your HEIC source. If the original uses Display P3 or sRGB, the AVIF output maintains the same color space.
