Where do you start when you need to resize pictures in Windows 7? Of course, the first and most obvious choice would be to use the built-in graphic editor. However, the MS Paint options are very limited in this respect: all you can do is resize each photo individually and hope that the output quality is satisfactory, since there’s no way to manage it. What if you want to resize image batches fast or need more control over output quality? The best option is to get a specialized photo resizer for Windows 7 – Movavi Photo Batch. This convenient software tool will help you compress large amounts of images at once.

All you need to start resizing your pics in bulk is download and install Movavi Photo Batch on your computer – both 64 bit and 32 bit versions of Windows will do fine – then read the following tutorial to find out how it works.

Step 1: Install Movavi’s Picture Resizer for Windows 7

Step 2: Add Images You Want to Resize

To add your files, click the Files button and choose each one individually or use the Folder option to upload an entire folder for resizing. Alternatively, you can add pictures and folders by dragging them to the working area of the program.

Step 3: Reduce the Size of Your Images

In Movavi Photo Batch, you’ll find a wide choice of options to change the dimensions of your photo. Switch to the Resize tab to choose the desired Resize mode from the drop down menu:

  • Scale to width allows you to set an exact width in pixels for all images added to the program, image height will be adjusted accordingly to maintain proportions.
  • Scale to height works similarly, but lets you enter the desired image height and adjusts image width to keep the aspect ratio.
  • Scale by percentage resizes the image proportionally by the percentage you define in the respective field, that means if you set the desired size to 80%, the image will be scaled down by 20% width and height, maintaining the aspect ratio.
  • Maximum size allows you to set the maximum height and width, into which bigger images will be fitted without cropping or stretching. Smaller images remain unaffected.
  • Scale to size resizes images to match the specified size while maintaining original proportions. Bigger images will be scaled down and smaller images enlarged to fit the specified size.
  • Custom size lets you define the exact height and width of the resulting images. This setting ignores proportions and will distort your photos if they have a different aspect ratio.

If you would rather change image resolution by cropping your pictures, read this tutorial to find out how it’s done.

Step 4 (Optional): Reduce File Size by Defining Format and Quality

Skip this step if all you want to do is change the resolution of your images.

File size matters when you need to email your pictures, upload them to your website or a social network, or free some additional space on your HDD. Changing image resolution helps reduce the file size, but you can make your images ‘weigh’ even less if you convert them to a format with a higher compression rate and adjust its export quality. To do this in Movavi Photo Batch, switch to the Format & Quality tab and choose the desired format from the Output format list. Choose JPEG as the output format and adjust the JPEG Quality slider to 70-80% – this will significantly reduce the file size without visible pixelation and other glitches.

Step 5: Export Your Downscaled Images

Once you’ve set up the desired size for your images, save them to apply the changes. Press the Batch Export button to open the program dialogue with the available options. Use the option Save to a new folder to export your images in a different directory – you can use the default output folder or browse for any other one. Select Save to original folder and back up originals to move the original files to the default backup directory or choose another one if you like. You can also Replace originals when you save the downscaled pictures. Choose this option ONLY if you are completely sure you’re ok with discarding originals, because they will be lost without the possibility to restore them. The option Rename and save next to the originals adds the exported photos to the original folder with an altered file name without moving or deleting the original images. Once you’ve chosen the option that suits your needs best, press OK to start exporting and wait just a little bit for the resize process to complete.
