Convert WebP to PNG on Mac — 3 Free Ways

Mac users have several free options for converting WebP to PNG — from the built-in Preview app to a browser tool that handles batches. This guide covers all three, so you can pick whatever fits your workflow.

Method 1: Use Mac Preview (Built-In, Single Files)

Preview has supported WebP since macOS Ventura (13) and newer. Here’s how to export to PNG:

1. Open your WebP file in Preview (double-click, or right-click → Open With → Preview).
2. Go to File → Export.
3. Change the format dropdown to PNG.
4. Click Save.

Preview handles transparency automatically — the alpha channel is preserved in the output PNG. Note: for macOS Monterey and earlier, Preview may not open WebP. Use the browser method below.

Method 2: Browser Converter (Batch, Any macOS Version)

Ibis WebP to PNG works in Safari, Chrome, or Firefox on any Mac:

1. Open the tool in your browser.
2. Drag your WebP files onto the drop zone, or click to browse.
3. Files convert instantly.
4. Download individual PNGs or a ZIP for batch conversions.

This method works on macOS Monterey, Ventura, Sonoma, and older versions. No Homebrew, no App Store, no admin password.

Method 3: Terminal (Quick One-Liner for Developers)

If you have Homebrew and ImageMagick installed, you can convert from Terminal:

Install: brew install imagemagick

Convert: convert input.webp output.png

Batch: for f in *.webp; do convert "$f" "${f%.webp}.png"; done

ImageMagick preserves transparency and handles all WebP variants including animated WebP (first frame). Best if you’re already comfortable in Terminal and processing large batches via script.

Which Mac Method Should You Use?

Quick rule of thumb: Preview for a single file on a recent Mac. Browser tool for batches or older macOS. Terminal only if you’re scripting a workflow. The browser method has the fewest requirements and handles transparency, batch processing, and all macOS versions.

Frequently Asked Questions

Can Mac Preview convert WebP to PNG?

Yes, but only on macOS Ventura (13) and later. Older macOS versions may not open WebP in Preview at all.

Does the browser-based method work on Safari for Mac?

Yes. Ibis WebP to PNG works in Safari on macOS, no extensions needed.

Will transparency be preserved when converting on Mac?

Yes, all three methods preserve the alpha channel.

I have hundreds of WebP files — what's fastest on Mac?

The browser tool handles batches with drag-and-drop. For very large batches (100+ files), a Terminal loop with ImageMagick is faster.
