Resize Image by Pixels or Percentage
Different websites or applications have varying requirements for image dimensions, often specifying a particular width and height, while others may only require a smaller version of your original photo.
ToolsGuru provides you with the option to adjust your image size to meet these requirements.
Resize Image to Exact Width and Height
If you need an image in specific dimensions for uploading to a website, you can adjust its width and height in pixels. For example, you can resize any of your photos to dimensions like 500 × 500 pixels or 1200 × 630 pixels.
This is useful when preparing images for online forms, profile pictures, website banners, or digital documents.
Resize Image by Percentage
If you do not know the exact pixel dimensions required for an image, you can resize it by using a percentage of its original size. For example:
- 50% reduces the original width and height by half.
- 75% reduces the dimensions to three-quarters of the original.
- 100% keeps the original dimensions.
