HEIC to AVIF Converter

HEIC to AVIF Converter

This tool accepts HEIC files, the format phone cameras produce: large dimensions, a wide colour range and orientation recorded as metadata rather than in the pixels. The result is AVIF, a modern web format that keeps transparency and reaches a smaller size at comparable quality — at the cost of older software that may not open it.

How to convert HEIC to AVIF

1. Select or drag HEIC files into the upload area.
2. Confirm that the requested output format is AVIF.
3. Start the conversion and review the status of each file.
4. Download each result once processing has finished.

Convert several files in one batch

The interface currently accepts up to 10 files per batch. Files are processed one after another; duplicates, mislabeled files and damaged files may be skipped or reported as errors.

File size after conversion

The size usually falls noticeably compared with older formats at the same visible quality. That is the main reason to use this format.

Check the result

Check gradients, skin tones and areas of flat colour, and confirm the file opens in the application you actually publish through. Check the orientation first. If a photograph comes out rotated, the cause is orientation metadata that the target format does not carry.

Limits worth knowing

This tool changes the file format. It does not guarantee that every piece of metadata, every format-specific property or every embedded object survives the conversion. Keep the source file and test the result in the application where you plan to use it.

Frequently asked questions

Will every program open this format?

No. Current browsers do; older image editors and some operating-system previews may not.

Is the quality lower than the source?

It can be — the format compresses lossily by default — but at a smaller size than older formats reach for the same appearance.

Why is my photograph rotated?

Because the source recorded orientation as metadata and the result stores the pixels as they physically are.

Is my original file replaced?

No. The file on your device is left untouched.
