- Launch Photos and select your image, or multiple images.
- Head to File > Export 1 Photo (or however many you are resizing).
- Under Size you can choose Full Size, Large, Medium or Small presets, and Custom allows you to set your own size (in pixels).
- Choose Custom to specify a maximum Width or Height, or choose Dimension to limit both width and height to the number you provide.
- Hit Export and choose where you want to save the image.
You can choose the filetype, compression quality, whether to omit embedded location information, and choose a color profile if you want to.
Note: You also have the option to Export Unmodified Original, which is what you should choose if you’re printing your images or plan on editing them in an external editor like Photoshop or Pixelmator.
*Another option that Firefox has nowadays, which I really like is “Reader View”. Basically it strips away all formatting from the website, and gives you just the “text” of the article. Very handy for getting rid of obscene ads and sidebar content quickly.
