How to change picture size on MacBook Pro?

 

Adjusting picture size on a MacBook Pro can be accomplished using various methods and applications. The process involves resizing images to meet specific dimensions or file size requirements.

Resize pictures on MacBook Pro

Changing picture size on a MacBook Pro can be done using several built-in and third-party applications, offering versatile ways to resize images according to specific requirements. Here’s a comprehensive guide:

  1. Preview Application: Open the image in the Preview app. Navigate to “Tools” in the menu bar and select “Adjust Size.” You can input the desired dimensions in pixels, inches, or centimeters. Ensure “Scale proportionally” is checked to maintain the original aspect ratio while resizing.
  2. Photos Application: Open the image in the Photos app. Click on “File” in the menu bar and select “Export.” Choose the image size from the available options or enter custom dimensions. Click “Export” to save the resized image.
  3. Third-Party Applications: There are various third-party applications like Adobe Photoshop, GIMP, or Pixelmator that offer more advanced image editing features, including resizing. Open the image in the chosen application, access the resize tool, input the desired dimensions, and save the changes.
  4. Online Tools: Several online tools like PicResize, ResizeImage.net, or Canva provide easy-to-use interfaces for resizing images. Upload the image, specify the desired size, and download the resized image.

When resizing images, ensure to maintain a copy of the original file to prevent loss of data. Always review the image quality after resizing to avoid any degradation due to the resizing process.

Can images be resized in bulk or multiple images simultaneously?

Yes, on a MacBook Pro, resizing multiple images simultaneously is possible through various methods and applications. One of the convenient ways is using the Preview app, where you can adjust the dimensions of multiple images collectively. Open Preview, then select multiple images by holding down the Command key while clicking on the desired images. Afterward, go to the “File” menu, choose “Open With,” and select “Preview.” With the images open in Preview, go to the “Tools” menu, select “Adjust Size,” and input the new dimensions. This action resizes all the selected images to the specified dimensions, helping maintain uniformity across the bulk of images.

Additionally, third-party apps like Adobe Photoshop or specialized batch image resizers provide more advanced options. These tools enable resizing multiple images simultaneously with increased control over settings like image format, quality, and other specifications. These applications often have functionalities that allow users to save time by processing images in bulk, ensuring consistent size, resolution, and file format adjustments across a large number of images at once.

Do third-party applications offer more advanced resizing features?

Yes, third-party applications often provide more advanced and comprehensive features for resizing images compared to built-in options like Preview on a MacBook Pro. Applications such as Adobe Photoshop, GIMP, or specialized batch image resizers offer an array of advanced tools and functionalities for image manipulation and resizing. These applications allow users to perform precise adjustments to image dimensions, photo size, and image quality, catering to specific requirements.

With third-party software, users have more control over various aspects of image resizing, including customizing the output file format, adjusting the image file size, and selecting the desired image formats (JPEG, PNG, TIFF, etc.). These tools often offer batch processing capabilities, enabling the resizing of multiple images at once while maintaining the desired quality and dimensions. Moreover, they provide advanced settings to retain the quality of the original image or to compress images without compromising their visual integrity, which can be particularly useful when dealing with a large number of pictures that need resizing or optimization for various purposes.

What considerations should be kept in mind to maintain image quality while resizing?

When resizing images, maintaining image quality is crucial. Consider the original file format and dimensions, as well as the purpose of the resized image. If you’re reducing an image’s size, the reduction shouldn’t be too drastic, as significant reductions may result in visible pixelation or loss of clarity. Reducing the image to around 80% or less of its original size generally retains better quality. Conversely, if enlarging an image, it’s best to do so conservatively to prevent pixelation and maintain clarity. Utilize editing software that allows you to view the image at its actual size or zoom in to assess the quality before finalizing the changes.

JPEG images are a common file format known for their lossy compression, meaning they can lose quality with each save. When repeatedly resizing and saving a JPEG image, the loss of quality can become noticeable. To preserve image quality, consider saving the resized image in a lossless format like PNG or TIFF, especially if you need to maintain high image quality. Additionally, pay attention to the file size when resizing images, as larger files occupy more storage space. Compressing images or choosing an optimal file format while resizing can help balance quality and file size, ensuring images remain clear and suitable for their intended purpose without consuming excessive storage space.
