Convert PNG to AVIF on Mac, Windows, iPhone, and Android

You don't need Photoshop, ImageMagick, or any desktop software to convert PNG to AVIF. The browser-based PNG to AVIF converter on WildandFreeTools runs on every major platform — Mac, Windows, iPhone, Android — with no install and no account.

This guide covers the exact steps for each platform so you can get smaller AVIF files regardless of what device you're on.

Convert PNG to AVIF on Mac

macOS supports AVIF natively starting with macOS 13 (Ventura), and browsers have supported it for longer.

1. Open Chrome, Firefox, or Safari (Safari 16+ on macOS Monterey and later).
2. Navigate to the PNG to AVIF converter on WildandFreeTools.
3. Drag one or more PNG files from Finder directly onto the tool's drop zone, or click to open a file picker.
4. Adjust the quality slider if needed (default 50 is fine for most images).
5. Click Download or Download All to save your AVIF files to your Downloads folder.

To preview the AVIF file on Mac: double-click it in Finder to open in Preview. Preview on macOS 13+ opens AVIF files natively.

If you're on an older macOS version, Chrome is the safest browser to use — it has supported AVIF longer than Safari.

Convert PNG to AVIF on Windows

1. Open Chrome or Edge (both have supported AVIF for several years).
2. Visit the PNG to AVIF converter.
3. Drag PNG files from File Explorer onto the tool, or click to browse and select files.
4. Set quality and click Convert, then Download.

To preview AVIF files on Windows 11, you can use the native Photos app — Windows 11 includes AVIF codec support. On Windows 10, you may need to install the HEVC Video Extensions from the Microsoft Store to view AVIF files in Photos. Alternatively, open the file in Chrome by dragging it into the browser window.

Command-line alternative: if you use the terminal regularly, browser-native processing engine -i input.png output.avif or the libavif tools work on Windows. But for quick one-off conversions, the browser tool is faster.

Convert PNG to AVIF on iPhone and iPad

1. Open Safari on your iPhone or iPad (iOS 16+ for AVIF support; iOS 16 runs on iPhone 8 and newer).
2. Go to the PNG to AVIF converter.
3. Tap the upload area. You'll see options to select from your Photo Library or Files app.
4. Select one or more PNG files. If they're in your camera roll, they're likely JPG — PNG files would typically be in your Files app or downloaded from elsewhere.
5. After conversion, tap Download. The AVIF file saves to your Files app under Downloads.

To find and use the downloaded file: open the Files app, tap Browse, then look in On My iPhone > Downloads. You can AirDrop the AVIF to your Mac, share it via iCloud Drive, or upload it directly from the Files app.

Convert PNG to AVIF on Android

1. Open Chrome on your Android device (AVIF has been supported in Chrome for Android since Chrome 89).
2. Navigate to the PNG to AVIF converter.
3. Tap the upload area. Choose files from your Downloads folder, Google Drive, or file manager.
4. After conversion, tap Download to save to your Downloads folder.

To confirm the download: open your file manager app (or check Notifications for the download confirmation). AVIF files can be previewed directly in Chrome by opening them from the file manager — just long-press and select Open With > Chrome.

Samsung Gallery on recent Galaxy devices also opens AVIF files natively.

Frequently Asked Questions

Do I need to install any software to convert PNG to AVIF on Mac or Windows?

No. The browser-based converter requires only a modern browser — Chrome, Firefox, Edge, or Safari 16+. No desktop software, plugins, or codecs need to be installed.

Can I view AVIF files on older iPhones?

AVIF is supported on Safari for iOS 16 and above, which runs on iPhone 8 and newer. Older devices running iOS 15 or earlier cannot display AVIF in Safari. For those devices, stick with PNG or WebP.

Is the conversion quality the same on mobile vs desktop?

Yes. The same quality slider settings produce the same output regardless of device. The conversion speed may be slower on mobile due to less processing power, but the output quality is identical.

Are my files safe when converting on a phone?

Yes. All conversion happens locally in your browser. Your PNG files never leave your device — nothing is uploaded to any server.
