Best image converter for Mac

Four ways to convert images on a Mac.

Use it first.

• Pros: Nothing to install, and it handles the common formats.
• Cons: Slow for large batches.

Toolbox is a Mac app with many tools in one, sold as a one-time purchase with no subscription.

• Pros: Drop a folder, pick a format and quality, and choose whether to keep metadata. Originals stay as they are.
• Cons: Fewer formats than XnConvert, and paid.

Better than Toolbox if you need rare formats.

• Pros: Free for private use and very capable, with many batch actions.
• Cons: Dense interface, and company use needs a paid license.

Good if you also convert media files.

• Pros: Converts video, audio and images with drag and drop; a trial is offered.
• Cons: Permute 4 needs macOS 26 and Apple Silicon.

We looked at what each app does for this one job, what it costs, and where it runs. Prices and features were checked on each maker's own site on 2026-11-03 and can change. Where a price page did not show a figure we could confirm, the table says to see their site.

Toolbox is our own app, so treat our ranking with that in mind. We list it where it fits the job and say plainly when another app is the better pick. Toolbox needs macOS 15 Sequoia or later. We looked at batch support, supported formats and whether files stay on your Mac.
