You might think, "I’ll just right-click and convert using any old app," but not all software handles conversions the same way. Stick with solid apps like Preview or the Photos app on Mac for the best results. You don’t want to end up with low-quality conversions from random third-party apps that might mess with your images. After converting, check the file size of the JPG. Sometimes, you’ll find that the JPGs are way larger than expected, especially if you’ve kept the quality high. It can be easy to fill up your storage space if you’re not paying attention. If size matters, don’t be shy about adjusting the quality when you save it.
