Why Convert AVIF to HEIC?
Our engine reads a file built around high-efficiency images for fast-loading modern websites and rebuilds it aiming to preserve this: roughly half the file size of JPG at similar visual quality — rather than producing a generic, lowest-common-denominator result.
AVIF is a modern AV1-based compressed image format, commonly used for high-efficiency images for fast-loading modern websites. That focus comes with a real limitation: unsupported by older browsers and some legacy software. HEIC doesn't share that problem — its strength: roughly half the file size of JPG at similar visual quality.
The short version: AVIF is optimized for high-efficiency images for fast-loading modern websites, HEIC is optimized for space-efficient photo storage on Apple devices, and this converter exists for the moment those two needs don't line up.

Frequent Questions
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
Why would I need HEIC instead of just keeping AVIF?
Mainly when your workflow specifically calls for space-efficient photo storage on Apple devices — that's HEIC's whole reason for existing, and AVIF isn't built to provide it, since it's focused on high-efficiency images for fast-loading modern websites instead.
Why does HEIC exist as a separate format instead of everyone just using AVIF?
Because they're built for different jobs — AVIF is aimed at high-efficiency images for fast-loading modern websites, while HEIC is aimed at space-efficient photo storage on Apple devices. Neither format is "better," they just fit different parts of a workflow.
Is HEIC objectively better than AVIF?
Not objectively — HEIC is better specifically for space-efficient photo storage on Apple devices. For high-efficiency images for fast-loading modern websites, AVIF is still the right tool; that's exactly why both formats exist.
Do I need any special settings before uploading my AVIF file?
No special setup is required — upload the file as-is. AVIF files meant for high-efficiency images for fast-loading modern websites convert most predictably; unusually exported or non-standard files are the most common reason a specific one might need extra attention.
