If you are struggling with corrupted AVIF files on a Mac, read on to learn how to repair corrupted AVIF to JPG on a Mac!

Why Standard AVIF to JPG Tools Fail on Mac

Most AVIF conversion guides assume your files are healthy. But if an AVIF is corrupt (due to incomplete downloads, transfer errors, or storage issues), standard tools will fail. Attempting to convert a damaged AVIF using Preview, online converters, or command-line tools often results in:

1. ❌ "File format not supported" errors
2. ⚠️ Blank/partial previews
3. ⛔ Complete conversion failure

In this case, file repair is required before conversion. This is where specialized tools like EaseUS Fixo Photo Repair become essential for Mac users.

This powerful and trusted image repair tool helps repair severely damaged AVIF files, repair corrupted HEIC files, etc., making the repaired AVIF files convert to JPG or PNG files without quality loss.

Besides, it converts an RSV file to MP4 to repair it and make it play normally on a Sony camera, and the entire process requires no Terminal command skills.

How to Undo Corrupted AVIF to JPG on Mac

Follow the steps below to repair & convert AVIF to JPG with EaseUS Fixo Photo Repair:

Step 1. Launch EaseUS Fixo on your Mac, go to the "Photo Repair" tab and click the "Add Photo" button to add the corrupted photos, including JPEG, PNG, JPG, CR3, CR2, NEF, NRW, RAF, etc.

Step 2. Select a photo and click the "Repair" button to start the single photo repair process. If you want to repair all the corrupted photos, click "Repair All".

Step 3. Click on the eye icon to preview a repaired photo and click "Save" to save it on your Mac. Choose "Save All" to save all the repaired photos. Click "View Repaired" to locate the repaired folder.

After repairing the corrupted AVIF files, you can change the file format from AVIF to JPG using online AVIF converters, the macOS Preview app, or Terminal command lines. Here are the pros and cons of the three solutions:

Tools	Advantages	Disadvantages
Online AVIF to JPG Converters	No installation; Supports JPG output.	Cannot repair corruption – fails if AVIF is damaged. Privacy risks (uploading private images). File size limits (usually 50-100MB).
macOS Preview App	Easey steps: Open AVIF in Preview > File > Export > Choose JPEG.	Only works if AVIF isn’t corrupted – useless for unopenable files. No batch support.
Command Line (avifdec)	No installation; For technical users via Homebrew.	Fails on corrupted AVIFs. Requires Terminal expertise.

Why Do AVIF Files Get Corrupted on Mac

Understanding the cause helps prevent future loss:

1. 1. Incomplete Downloads/Transfers: Interrupted internet or USB disconnections.
2. 2. Software Bugs: Photo editors (e.g., Affinity Photo) crashing during AVIF export.
3. 3. Storage Errors: Bad sectors on SSDs, SD cards, or external drives.
4. 4. macOS Compatibility Gaps: Older macOS versions (pre-Big Sur) lack native AVIF support.

Prevention Tip: Always eject drives properly and use reliable editing software. For corrupted files, repair immediately with tools like EaseUS Fixo to prevent permanent loss.

AVIF to JPG on Mac FAQs

Here are questions people frequently ask about AVIF files on a Mac:

1. Can I convert AVIF to JPG without losing quality?

Yes! Use lossless tools like EaseUS Fixo or `avifdec` (if files are healthy). AVIF’s efficiency often means JPGs retain near-identical quality at slightly larger sizes.

2. Why won't my AVIF open in the Preview or Photos app?

Two likely reasons:

1. 1. Corruption: File damage from transfer/editing errors.
2. 2. macOS Version: Older macOS (pre-11.0 Big Sur) lacks native AVIF support.

And the solution is to repair the corrupted files with Fixo first, then convert to JPG.

3. Is there a FREE way to repair corrupt AVIF on Mac?

Few reliable free options exist. EaseUS Fixo offers a free trial to preview repairs for 3 files. For critical recovery, its paid version is cost-effective.

Conclusion

Don't let corrupted AVIF files lock away your photos. While macOS struggles with AVIF compatibility and corruption, EaseUS Fixo Photo Repair for Mac delivers a one-click solution: repair damaged files first, then convert them to JPG – all without command lines or privacy risks.
