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)
- Open your image in Preview.
- Go to File > Export....
- Choose your desired format from the Format dropdown (JPEG, PNG, TIFF, etc.).
- 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.
- Right-click your image file in Finder.
- Select Quick Actions > Convert Image.
- Choose your format (JPEG, PNG, or HEIF) and size.
- 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.
- Head to the imgKonvert Homepage to start.
- Drag in your files.
- Select your output format.
- Click Convert All.
- 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.
