Convert Image Formats Directly in the Finder

If you need to convert images to JPEG, PNG, or (unlikely) HEIF, try this hidden Find-er feature: Control-click an image in one of those formats or other common image formats like TIFF, GIF, or PSD, and choose Quick Actions > Convert Image. A dialog lets you choose the destination format, the image size, and whether you want to pre-serve metadata. For straight conversions, stick with Actual Size, but if your goal is to shrink the file as well, you can choose a smaller image size. Leave Preserve Metadata selected unless you want to remove things like location metadata for privacy rea-sons. You can even select multiple files to convert them all at once.
