Convert HEIC to AVIF
Convert HEIC to AVIF for the smallest modern-format files. AVIF matches HEIC on size with wider (non-Apple) compatibility.
HEIC and AVIF use similar generation-of-video-codec compression. Converting HEIC to AVIF preserves file-size efficiency while broadening compatibility from Apple-only to every current browser.
Both formats use lossy compression, so re-encoding compounds slightly. Land at AVIF quality 60 (equivalent to WebP q80) for imperceptible loss.

Frequently asked questions
- How do I convert HEIC to AVIF?
- Drop your HEIC file into the tool above. It's converted to AVIF in the browser and ready to download. Multiple files can be converted at once.
- Why convert HEIC to AVIF?
- HEIC and AVIF use similar generation-of-video-codec compression. Converting HEIC to AVIF preserves file-size efficiency while broadening compatibility from Apple-only to every current browser.
- Is any quality lost when converting to AVIF?
- Converting between lossy formats (like JPG to WebP) involves one round of re-encoding, so there is theoretically some quality loss — but at the default quality setting it's visually indistinguishable. Converting to a lossless format (PNG) doesn't lose data from the source.
- Does the AVIF file work everywhere the HEIC did?
- Modern browsers, image editors, and platforms all support AVIF. Older tools (2015-era software, some third-party services) may not — if you need maximum compatibility, JPEG or PNG remain the safest fallbacks.
- Are my files uploaded anywhere?
- No. Conversion runs entirely in your browser using the Canvas API. Files never touch our servers, which matters for pre-publication work, client assets, or anything sensitive.
