Here’s how you can convert a JPEG image to PNG or HEIF and vice versa straight from macOS on Mac - no apps required.

You can convert between JPEG, PNG, and HEIF file formats in macOS on your Mac natively - no third-party app required at all

Converting images is actually a very straightforward process - just download Photoshop or any other image editing software, open the image you want to convert inside said software, and export it to the format of your choice. See, easy peasy. However, that string of tasks in order to convert a JPEG, PNG, or HEIF image to something else is not everyone's cup of tea at all. You can avoid it altogether if you're using a Mac and running the latest software update.

See, the thing is, macOS allows you to convert between JPEG, PNG, and HEIF files instantly without the need to install any third-party software at all. Once you've mastered this, you'll wonder why we even download apps for such a simple task.

Anyway, let us take you to the tutorial itself because that's why you're here.

Tutorial

Step 1. Find the image you wish to convert - it can be a JPEG, PNG, or HEIF. If that image is in the Photos app, you might want to export it to the desktop before you can do anything.

Step 2. Right-click on the image.

Step 3. Hover the mouse pointer over Quick Action to reveal more options.

Step 4. Now simply click on Convert Image.

Step 5. You now see a box with a couple of options - Format and Image Size. Use the Format drop-down to select the format to which you want to convert the image - JPEG, PNG, or HEIF. You can use the Image Size drop-down to select how big you want the image to be. If you want to preserve the actual quality, then select Actual Size otherwise, go with something else - Small, Medium, or Large.

Step 6. Once you have made your choices, click on the 'Convert to JPEG/PNG/HEIF' button.

See, super easy, as I told you.

The only downside to this is a very obvious one - you get an extremely limited number of formats to convert to. But it’s highly likely you wouldn’t want to convert to anything else anyway. Secondly, you don’t get advanced controls for fine-tuning the converted image. You only get a vague ‘Image Size’ option which is more than enough for most of you out there but can be slightly annoying for those who want a little extra, such as what exact resolution to convert the image to.
