How to Convert AVIF to JPG on Windows, Mac, iPhone or Android

To convert AVIF to JPG, select your saved AVIF in a converter, choose JPG output and download the finished copy. Open that JPG in the app or form that needs it. ImageFinch runs the conversion in your browser, so the image stays on your device.

Our three-file test had a useful surprise: at quality 90, the photo became slightly smaller, but the transparent graphic and text board became larger. Getting a JPEG that opens where you need it matters more than assuming conversion will save space. Below, you can follow the steps, inspect those results and download the test files yourself.

Convert an AVIF image to JPG: the quick steps

Check the receiving service before converting. It may require JPEG, a maximum file size and a particular width or height at the same time. Format conversion only solves the format part. If you must submit an unaltered original, follow that service’s instructions instead of editing the photo.

Use the browser workflow on your device

The conversion controls are the same across devices. The file picker and download location belong to your browser and operating system, so their wording can vary. The screenshots and measurements in this guide come from desktop Chrome; the phone instructions below describe the general browser workflow, not a device-by-device test.

How to convert AVIF to JPG on Windows

Open the tool in a current browser and select the AVIF from its folder in File Explorer. You can also drag the actual file into the selection area. Convert it, download the JPG, then open the browser’s downloads list to find the saved copy. If the browser asks where to save, choose a folder you can find again.

If a desktop photo viewer cannot open AVIF, the browser workflow can still be worth trying. It needs a browser that can decode that particular source file. A newer browser cannot fix a damaged or incomplete download, so return to the source if the image fails to load.

How to convert AVIF to JPG on Mac

Choose the saved AVIF through the browser’s file picker, or drag it from Finder into the tool. Keep JPG as the output, run conversion and download the new file. Find it through the browser’s downloads list and open the JPG from there. If the receiving app still rejects it, check that you selected the downloaded copy rather than the original in Finder.

How to convert AVIF to JPG on iPhone or iPad

Open the converter in your browser and tap the selection area. For an AVIF saved as a file, use the file-browsing option and locate the original in Files or your saved downloads. A photo-library picker may offer a different representation; select the actual AVIF when you want to convert that file.

After conversion, tap Download Image and check the browser’s downloads interface or the Files app. The destination depends on your browser settings. If you need the JPG in Photos, open the downloaded copy and use the available sharing or save-image action. Keep the tab open until processing finishes.

How to convert AVIF to JPG on Android

Choose the original through the browser’s file picker, convert it and tap Download Image. Look in the browser’s Downloads list or your file manager. If the JPG does not appear in your gallery immediately, find it through Downloads before assuming conversion failed. Open the saved copy and select that file for your next upload.

What changes when AVIF becomes JPG?

An AVIF to JPG converter reads the source image and saves its pixels in JPEG format. In this workflow, width and height stay the same; the quality setting changes how JPEG compresses the image, rather than its dimensions. The original file remains separate. A successful conversion does not mean every feature of the AVIF survives.

AVIF can hold transparent areas, animation and HDR: a wider range of brightness than an ordinary image. This browser tool makes a still JPG copy. Keep the original if those features matter, and compare the result in the app where you plan to use it.

Real examples: file size and quality after conversion

We ran three controlled samples through the same conversion function used by ImageFinch’s tool in desktop Chrome 155 on October 23, 2026, with JPG output at quality 90 and no resizing. We reopened the outputs to check their JPEG encoding and dimensions. The photo and transparent graphic reuse this site’s demonstration assets; the text board was created for this guide and encoded as AVIF at quality 75 before conversion. These are demonstration files, not a representative camera-photo benchmark.

The photo became slightly smaller, while the graphic and text board became larger. That is why conversion should start with the required format, not an assumption about saving space. These byte counts describe the actual files in the links below; the article’s WebP comparison images are display previews. A different source, browser or quality setting can produce different results.

• Photo sample: original AVIF (117,209 bytes)
• Photo sample: converted JPG (115,205 bytes)
• Transparent graphic: original AVIF (2,702 bytes)
• Transparent graphic: converted JPG (7,341 bytes)
• Text board: original AVIF (15,450 bytes)
• Text board: converted JPG (43,598 bytes)

Which quality setting should you use?

Start with 90 and inspect the result at its intended display size. Look at lettering, hair, foliage and high-contrast edges. If you need a smaller file, try a lower quality setting from the original and compare again. A value of 90 is an encoder setting; it does not mean 90% of the original quality or a 90% reduction in bytes.

If the form accepts JPEG but the file is too large, use the JPG compressor or the 100KB target tool for an applicable limit. Change dimensions with the image resizer only when the destination allows it. Recheck both measurements before uploading.

Why did the transparent background turn white?

JPEG cannot store transparency, also called an alpha channel. ImageFinch places the image onto a white background before saving the JPG. Empty areas and partially transparent edges are blended with that white. Converting the JPG back to PNG afterwards does not restore the removed transparency.

For a logo, cutout or soft shadow that needs transparency, choose the AVIF to PNG converter instead. PNG can preserve an alpha-capable output, but it cannot undo damage already present in the AVIF and may use more storage.

How to batch convert AVIF to JPG and download a ZIP

Select several AVIF files together, or use + Add More after the first selection. Run conversion, review each result and choose Download All as ZIP for the completed copies. The ZIP is a container holding the JPG files; it is not itself a JPG and may not be accepted by an image-upload field. Extract it and select an individual image when required.

The current selection limit is 100 files, with a 100 MiB limit per input file. Those are ceilings, not a promise that every device can process that much at once. Decoded images use memory beyond their compressed file size. Start with a small batch on a phone, keep the tab open and download completed results even if another file fails.

Fix a JPG that still will not upload

An “AVIF file not supported” message means the receiving app could not accept that file. After conversion, select the new JPG and check the rest of the upload rules. A file can be the right format and still fail a size or dimension limit.

Avoid repeatedly converting one export into another. Each lossy JPEG encode can introduce more artifacts. When trying settings, go back to the AVIF source and compare separate outputs. If the receiving service applies its own processing, inspect the uploaded copy as well as your local file.
