Each format defines its own compression scheme, color depth and feature set (transparency, animation, metadata). Converting HEIF to AVIF keeps the same visual content but rewrites it in a container that fits your target — a browser, a CMS, a print workflow or an archive.

Why convert HEIF to AVIF
Moving from HEIF to AVIF lets you solve a concrete compatibility, size or publication constraint: opening the file in a browser that does not support HEIF, shrinking its weight, flattening transparency, or simply matching the format expected by a CMS, a printer or a mobile app.
How the HEIF to AVIF conversion works
Your HEIF files are uploaded over HTTPS, decoded at full resolution, re-encoded as AVIF with its recommended default encoder settings, then returned as a download link. Up to 24 files can be processed in the same batch and grouped into a single ZIP if needed.
Quality and color fidelity from HEIF to AVIF
The conversion uses the native resolution of each HEIF source, honors EXIF orientation and embedded color profiles, and writes AVIF with balanced default parameters. No extra re-compression step is applied on top of the target encoder.
Private and temporary by design
Your uploaded HEIF files and their AVIF output stay on our servers for one hour so you can re-download them from any device, then they are wiped automatically. No account, no tracking, no watermark.
Frequently Asked Questions
Convert to AVIF when you need wider browser support, a lighter file, an animation, transparency or a format accepted by your publishing platform. Keep HEIF when the original is already the best fit for your use case.
Yes. You can drop up to 24 HEIF files at once and export them all to AVIF in a single operation. Each converted AVIF file can be downloaded individually or the whole batch can be retrieved as a single ZIP archive.
We decode each HEIF file at full resolution and encode the AVIF result with recommended default settings. No additional re-compression is applied, so the output looks virtually identical to the source at normal viewing sizes.
Yes, the reverse conversion is available as a separate page. However, each conversion step rewrites the pixels with a new encoder, so converting back and forth multiple times is not recommended when you care about fidelity.
Each file can be up to 10 MB. You can convert up to 24 images simultaneously.
No. Files are deleted automatically as soon as you download them, and at most after 1 hour.
