6 Best Image Converters for Mac in 2026

Need a JPG for an upload form, or a PNG that keeps its transparent background? I’ve rounded up six ways to convert images on a Mac, from Preview to apps that handle whole folders.

1. How to Convert

Mac · $29 once

This is my app. It handles almost any file, so you can use it for photos as well as video, audio and documents. Drop in your files and choose the output; it finds and runs the conversion tools for you.

  1. 1. Add your files. Drag your images into How to Convert.

  2. 2. Choose the output and convert. Pick the format you need, such as JPG or PNG, and click Convert.

2. XnConvert

Mac, Windows, Linux · Free for private/educational use; business license available

Choose this for repeat batches that also need resizing or renaming. Company use requires a licence.

  1. Open XnConvert’s Input tab and add your files or folder.
  2. Leave Actions empty for a format change only. If you need smaller dimensions, add Resize and keep the aspect ratio to avoid stretching.
  3. Select JPEG for ordinary photos or PNG for transparency. Save to a new folder, then click Convert. Check a few results before processing the rest.

JPG cannot keep a transparent background. Use PNG for a logo that needs to stay transparent.

3. Preview

Already on your Mac and quick for a single picture.

  1. Open the image in Preview and choose File → Export.
  2. Choose JPEG, PNG or another format, pick a location and click Save.
