Use Bulk mode when you want to resize multiple images using the same settings.
Add images
To add images, do either of the following:
- Drag multiple image files into the drop area.
- Click Drop or click to add images, then choose images from your Mac.
After images are added, they appear in a list with their file names and original pixel dimensions.
Add more images
When the list already contains images, click the Add images... row at the bottom of the list to choose more images.
If you add a file that is already in the list, Image Resizer skips the duplicate.
Remove images from the list
You can remove images before resizing:
- Click the X button on an image row.
- Select one or more rows and press Delete or Backspace.
Removing an image from the list does not delete the original file from your Mac.
Resize by dimensions
- Select Dimensions in the Output section.
- Enter the desired Width.
- Enter the desired Height.
- Click Resize Images.
- Choose the destination folder.
Every image will be resized to the width and height you entered.
Resize by ratio
- Select Ratio in the Output section.
- Enter a ratio greater than zero.
- Click Resize Images.
- Choose the destination folder.
For example, a ratio of 0.5 creates images at half of their original width and height. A ratio of 2 creates images at double their original width and height.
Choose the destination folder
Image Resizer asks for a destination folder after you click Resize Images. The resized files are saved into that folder.
Progress and results
While the app processes images, each row shows its status. When processing completes, the status area shows whether all images were resized or whether any files failed.
