How to Convert Image Formats on Mac (JPG, PNG, WebP)

Whether you're dealing with Apple's default HEIC format, or you need to turn a PNG into a WebP for your website, macOS has several ways to handle format conversion.

1. Using Preview (Standard Method)

  1. Open your image in Preview.
  2. Go to File > Export....
  3. Choose your desired format from the Format dropdown (JPEG, PNG, TIFF, etc.).
  4. Click Save.

2. Using Finder "Quick Actions" (The Speed Run)

If you are on a recent version of macOS (Monterey or later), you can convert without even opening an app.

  1. Right-click your image file in Finder.
  2. Select Quick Actions > Convert Image.
  3. Choose your format (JPEG, PNG, or HEIF) and size.
  4. Click Convert to....

3. Using imgKonvert (For Modern Formats & Bulk)

While macOS is great, its built-in tools often lack support for modern web formats like WebP and AVIF. They also aren't great for converting hundreds of files at once.

  1. Head to the imgKonvert Homepage to start.
  2. Drag in your files.
  3. Select your output format.
  4. Click Convert All.
  5. Our tool ensures your data remains secure throughout the conversion process.

Which Format Should You Use?

  • WebP: The best for websites (supported by all modern browsers).
  • HEIC: Great for saving space on your iPhone, but bad for sharing with Windows users.
  • PNG: Use this for logos or anything with a transparent background.
  • JPG: The universal standard for photographs.

Summary

Mac users have fantastic built-in options like Preview and Quick Actions for basic tasks. But when you need to step into the world of modern web optimization or high-volume conversion, imgKonvert is the most efficient companion for your Mac.
