How to Convert AVIF to JPG — Free, Browser-Based, Any Device (2026)
Table of Contents
AVIF is the newest mainstream image format, built on the AV1 video codec, and it compresses images more efficiently than both JPEG and WebP. The catch is that AVIF support is still patchy outside modern browsers — many desktop image editors, older operating systems, and a lot of everyday software simply don't recognize the .avif extension yet. If you downloaded or were sent an AVIF file and it won't open, converting to JPG is the fastest fix. This guide covers every free method.
1. Quick Answer
The direct answer: To convert AVIF to JPG, open convertlo.pro/avif-to-jpg.html in any modern browser, drag in your .avif file, and download the JPG — conversion happens locally, nothing is uploaded. On Mac (macOS Ventura or later), open the AVIF in Preview and use File → Export → JPEG. On Windows, the Photos app needs the AV1 codec extension to open AVIF at all; if you don't want to install it, a browser converter avoids the problem entirely.
| Method | Install needed? | Batch support | Privacy |
|---|---|---|---|
| Convertlo (browser) | No | Yes | Local, no upload |
| Mac Preview (Ventura+) | Built-in | Limited | Local |
| Windows Photos | Needs AV1 extension | One at a time | Local |
| XnView MP / IrfanView | Yes (free) | Yes | Local |
2. Why Convert AVIF to JPG
AVIF was standardized in 2019 and adopted by major browsers starting around 2020-2021. Its compression efficiency makes it attractive for websites, but the format's reach outside the browser is still limited. Common reasons to convert:
- Older photo editors — most versions of Photoshop, GIMP builds without the AVIF plugin, and many legacy tools don't open AVIF.
- Pre-2022 devices and older iOS/Android versions — AVIF support arrived in iOS 16 (2022) and varies across older Android versions and manufacturers.
- Upload forms and print services — most expect JPG/PNG specifically and reject or mishandle AVIF.
- Windows without the right codec — Windows can require installing the AV1 Video Extension before AVIF thumbnails or previews work properly.
- Sharing broadly — when you don't know what device or software the recipient is using, JPG guarantees it opens.
3. Method 1: Convertlo Browser Converter
Convertlo decodes AVIF and re-encodes it as JPEG entirely inside your browser. The file never leaves your device.
Works in any modern browser, desktop or mobile, no account needed.
Drop one or several files onto the converter, or click Browse to select from your device.
Conversion is typically near-instant. Click Download for each file or grab them as a batch.

Your images never leave your device. Works on any platform.
4. Method 2: Mac Preview
macOS Ventura (2022) and later support AVIF natively in Preview.
Double-click it — if your macOS version is too old, it may not open. Update macOS or use the browser method instead.
Click File, then Export, in the Preview menu bar.
Pick JPEG from the Format dropdown, set quality to 85-90%, and click Save.
5. Method 3: Windows Photos
Windows can open AVIF, but it usually requires the AV1 Video Extension and AV1 Image Extension from the Microsoft Store first — both free.
Search "AV1 Video Extension" and "AVIF Image Extension" and install both (free) if AVIF files aren't opening.
Use the three-dot menu → Save a copy → choose JPEG as the file type.
If you'd rather not install codec extensions, skip straight to Convertlo's browser converter — it requires no system-level codec support at all.
6. Batch Converting Multiple AVIF Files
Convertlo accepts multiple AVIF files dropped in at once for browser-based parallel conversion. For very large folders, free desktop batch tools like XnView MP or IrfanView (Windows) can process AVIF files once codec support is installed, converting hundreds of files to JPEG in one pass.
7. AVIF vs JPG — When to Keep Each
| Situation | Best format | Why |
|---|---|---|
| Publishing on your own modern website | AVIF | Best-in-class compression improves load speed and Core Web Vitals |
| Sharing with an unknown audience/device | JPG | Universal compatibility — opens everywhere, including older devices |
| Uploading to a form or print service | JPG | Most services explicitly support JPG; AVIF support is inconsistent |
| Archiving for long-term access | JPG or PNG | AVIF tooling could change; JPG's universal support is a safer long-term bet |
