AVIF produces very small files at good quality, which is why websites and some apps now serve it. The catch is that you can end up with an .avif file that older photo editors, email clients, document tools or upload forms simply refuse to open.
The fix is to convert it to JPG. This guide shows how to do that free in your browser, which quality to choose, and what you lose and keep in the process.
Key Takeaway: AVIF to JPG trades a little efficiency for compatibility. Expect the JPG to be larger than the AVIF at similar quality, and note that JPG cannot keep transparency.
Step by Step: Convert AVIF to JPG
- Open TinyPNG Now and drag your AVIF file onto the upload zone.
- Set the output format to JPG.
- Leave quality around 85-90% for a clean result, or lower it if you also need a smaller file.
- Download the JPG. You can convert several files at once by dropping them in together.
The conversion happens locally in your browser, so your photos are not uploaded anywhere.
Why Won't My AVIF File Open?
AVIF is a newer format. Current versions of major browsers can display it, but many desktop programs, older operating system image viewers, print services and upload forms do not recognize it yet. If a site gave you an AVIF when you saved an image, or a tool exported one, converting to JPG is the quickest way to make it usable. For the full format comparison, read WebP vs AVIF.
What You Gain and Lose
| Aspect | AVIF | JPG |
|---|---|---|
| Compatibility | Newer apps and browsers | Nearly everything |
| File size at same quality | Smaller | Larger |
| Transparency | Supported | Not supported |
Pro Tip: If your AVIF has a transparent background, convert it to PNG instead of JPG. JPG cannot store transparency. See WebP vs PNG vs JPG for how to choose.
Keep the original AVIF if you still plan to publish it on a website, since it will load faster there. Convert a copy for sharing and uploads.
Frequently Asked Questions
How do I convert AVIF to JPG for free?
Upload the AVIF to TinyPNG Now, choose JPG as the output format, keep quality around 85-90% and download. It runs in your browser with no signup and no upload to a server.
Why can't I open my AVIF file?
AVIF is a newer format. Many older desktop programs, image viewers and upload forms do not support it yet. Converting to JPG makes the image open almost anywhere.
Will converting AVIF to JPG reduce quality?
JPG is a lossy format, so there is a small loss, but at 85-90% quality it is rarely visible. Avoid converting back and forth repeatedly, since each lossy save adds more loss.
Why is my JPG bigger than the AVIF?
AVIF compresses more efficiently than JPG, so the same image is usually larger as a JPG. You can lower the JPG quality or use the compressor to shrink it again.
Does JPG keep a transparent background from AVIF?
No. JPG does not support transparency. If your AVIF has a transparent background, convert it to PNG or WebP instead.
