Convert AVIF to HEIC Online
Encoding is extremely slow (up to 10x slower than WebP) and browser support, while growing, is still not 100%. Converting to HEIC gives you a key advantage: roughly 50% smaller than jpeg at the same quality, with support for 10-bit hdr, depth maps, and burst sequences. HEIC is best for storing iphone and ipad photos at half the file size of jpeg with no visible quality loss.
Why Convert AVIF to HEIC?
Encoding is extremely slow (up to 10x slower than WebP) and browser support, while growing, is still not 100% — converting to HEIC overcomes this by providing roughly 50% smaller than jpeg at the same quality, with support for 10-bit hdr, depth maps, and burst sequences
HEIC is the right choice when you need to: managing iphone photo libraries with reduced storage consumption
Gain broader compatibility — HEIC works with Apple devices (native since iOS 11 / macOS High Sierra), Windows 10+ (with HEVC extension), limited Android support
Your AVIF files were created for storing hdr photography with wide color gamut for professional workflows, but now you need a format suited to different workflows

How to Convert AVIF to HEIC
Upload your AVIF file
Drag your .avif file onto the upload area or click to browse. We accept AVIF files up to 50 MB.
Choose HEIC as output format
Select .heic (High Efficiency Image Container) from the format list. Adjust quality settings if needed — higher quality means larger file size.

Frequently Asked Questions
Is the AVIF to HEIC conversion lossless?
expand_more
When both formats support lossless data, the conversion preserves all content. 10-bit color depth, HDR metadata, depth maps, and multiple images in a single container.
How large will my HEIC file be compared to the original AVIF?
expand_more
AVIF files are typically 5 KB – 8 MB, while HEIC files are typically 1 MB – 8 MB. The actual size depends on content complexity and any quality settings you choose.
What software can open the converted HEIC file?
expand_more
HEIC is compatible with: Apple devices (native since iOS 11 / macOS High Sierra), Windows 10+ (with HEVC extension), limited Android support.
What is the maximum file size I can convert?

PureConverter accepts AVIF files up to 50 MB. Your files are processed securely and deleted from our servers after conversion.
What's the difference between AVIF and HEIC?
expand_more
AVIF (AV1 Image File Format) is best for next-generation web images with the highest compression efficiency available today. HEIC (High Efficiency Image Container) is best for storing iphone and ipad photos at half the file size of jpeg with no visible quality loss. Key tradeoff: AVIF's advantage is achieves 50% smaller files than jpeg and 20% smaller than webp at equivalent quality, with hdr and wide color gamut support, while HEIC's advantage is roughly 50% smaller than jpeg at the same quality, with support for 10-bit hdr, depth maps, and burst sequences.
Pro Tips for AVIF to HEIC Conversion
For the best HEIC quality, start with the highest-resolution AVIF source available — lossy compression works better with more data to analyze
If your AVIF file has transparency, make sure HEIC supports it — HEIC may not preserve alpha channels
HEIC works especially well for: converting ios photos to jpeg or png for cross-platform sharing
Did you know? When you AirDrop an HEIC photo to a non-Apple device, iOS silently converts it to JPEG on-the-fly before sending — most recipients never realize the conversion happened.
