Convert JPG to AVIF on Any Device — Mac, Windows, iPhone, Linux

You can convert JPG to AVIF on any device — Mac, Windows, iPhone, Android, Linux, or Chromebook — without installing any software. The converter runs entirely in your browser, so the platform does not matter. Open the tool, drop your file, and download the AVIF. Here is the exact experience on each device.

JPG to AVIF on Mac (Safari and Chrome)

Both Safari and Chrome on Mac support the tool fully. The fastest workflow on a Mac:

1. Open the JPG to AVIF converter in Safari or Chrome.
2. Drag your JPG file from Finder directly onto the drop zone — or click to browse.
3. Adjust quality if needed (default 50 works great for most images).
4. Click download — the AVIF file saves to your Downloads folder.

There is no need for Preview export tricks, third-party apps, or command-line tools. The browser handles everything. Batch conversion works too — drag multiple files at once.

Mac Note: macOS Ventura and later can preview AVIF files natively in Quick Look. If you are on an older macOS, you will need to open AVIF files in Chrome or Firefox to preview them.

JPG to AVIF on Windows 10 and 11

On Windows, use Chrome or Edge — both support the conversion fully. Steps:

1. Open the converter in Chrome or Edge.
2. Drag your JPG from File Explorer onto the tool, or click to browse.
3. Download your AVIF file — it saves to your Downloads folder.

Windows 11 can open AVIF files in the Photos app natively. Windows 10 users may need to install the AV1 Video Extension from the Microsoft Store (free) to preview AVIF files in the Photos app and File Explorer thumbnails.

Alternatively, any modern browser (Chrome, Firefox, Edge) can open and display AVIF files directly — just drag the file into the browser window to verify the result.

JPG to AVIF on iPhone and iPad (Safari)

The converter works in Safari on iOS 15 and later. The process on iPhone:

1. Open the converter in Safari — tap the link from your bookmarks or type the URL.
2. Tap the upload area and choose a photo from your Camera Roll or Files app.
3. Tap the download button — the AVIF file saves to your Downloads folder in Files.

iPhone users often need AVIF conversion for a different reason than Mac or PC users — HEIC photos from an iPhone camera are sometimes exported as AVIF by web services, and you may want to convert a JPG back or forward between formats. The browser-based tool handles this without any app download from the App Store.

iOS note: Safari on iOS 16+ can display AVIF files. If you are on an older iOS, you may not see a preview after downloading, but the file is valid and will display correctly in supported apps and browsers.

JPG to AVIF on Android (Chrome Mobile)

Chrome on Android supports the full conversion workflow:

1. Open the converter in Chrome on your Android phone or tablet.
2. Tap the drop zone and select a JPG from your gallery or file manager.
3. Download the AVIF — it saves to your Downloads folder.

Chrome on Android has supported AVIF since version 85, so virtually all current Android devices can handle the conversion and preview. Samsung Internet also supports AVIF if you prefer that browser.

JPG to AVIF on Linux — Browser vs Command Line

On Linux, the browser method is the simplest option for most users. Open the converter in Firefox or Chrome, drag your JPG, and download the AVIF.

If you prefer the command line and need to convert large batches, you can use ImageMagick with AVIF support (requires libavif):

convert input.jpg -quality 50 output.avif

Or with browser-native processing engine (requires AVIF encoding support in your build):

browser-native processing engine -i input.jpg -crf 30 output.avif

For casual one-off conversions, the browser tool is faster and requires no dependencies. For scripted batch jobs converting hundreds of files, the command-line tools are more efficient once set up.

Frequently Asked Questions

Do I need to install an app on iPhone to convert JPG to AVIF?

No. The browser-based converter works in Safari on iOS 15 and later — no App Store download required. Just open the converter URL in Safari, select your photo, and download the result.

Does Windows natively support AVIF files?

Windows 11 supports AVIF natively in the Photos app. Windows 10 users can install the free AV1 Video Extension from the Microsoft Store to enable AVIF support in Photos and File Explorer. Any modern browser can also open and display AVIF files without any extension.

Is there a file size limit when converting on mobile?

There is no imposed file size limit — the conversion runs in your browser using your device's own processing power. Very large files (over 20 MB) may take longer on phones with less RAM, but there is no hard cap.

Can I convert JPG to AVIF on a Chromebook?

Yes. Chrome on a Chromebook fully supports the conversion. Drag your JPG file from the Files app onto the tool, adjust quality if needed, and download the AVIF. ChromeOS can also open AVIF files natively in the Files app image viewer.
