How to rescale images online?

  • Add all pictures you want to rescale to either by drag and drop section or choose file by click on input area.
  • Enter new width and height in pixels for the output image.
  • Click on Rescale button to rescale and download the rescaled image.
  • You can click on reset button if you want to rescale new file.
What is image rescale operation?
  • The `rescale` operation is used to change the size of an image to a specified width and height, similar to the `resize` operation. However, the `rescale` operation also changes the aspect ratio of the image if the specified dimensions are not proportional to the original dimensions.
  • The operation takes the new dimensions of the image. The dimensions are specified as a width and height in pixels, separated by an 'x'.
  • Please note that the `rescale` operation will not preserve the aspect ratio of the original image if the specified dimensions are not proportional to the original dimensions. If you want to maintain the aspect ratio, you should use the `resize` operation instead.
What are the uses of image rescaling?
  • The `rescale` operation has several uses:
  • Image Scaling: The `rescale` operation is used to scale images to a specific size. This is useful when you need an image to fit a certain width and height requirement, such as for a website or application.
  • Aspect Ratio Changes: Unlike the `resize` operation, `rescale` can change the aspect ratio of an image. This can be useful when you need an image to fit into a specific shape or area without maintaining its original aspect ratio.
  • Optimizing Images for Web: Rescaling images is crucial for web optimization. Large images can slow down a website's load time, so images are often rescaled to a smaller dimension to improve performance.
  • Preprocessing for Image Analysis: In image analysis tasks, it might be necessary to rescale images to a standard size before applying other operations.
  • Creating Thumbnails: The `rescale` operation can be used to create smaller versions (thumbnails) of larger images, which can be useful for preview purposes.
  • Automating Image Editing: If you have a batch of images that need to be rescaled to the same dimensions, you can use the `rescale` operation in a script to automate the process.
What is the difference between image resize and rescale?
  • Both `rescale` and `resize` operations are used to change the size of an image, but they handle the aspect ratio differently:
  • Resize: The `resize` operation changes the size of an image to the specified dimensions. If only one dimension (width or height) is provided, this tool maintains the original aspect ratio of the image. This means the image's proportions remain the same, and it won't be stretched or squished.
  • Rescale: The `rescale` operation also changes the size of an image to the specified dimensions, but it does not preserve the original aspect ratio if the specified dimensions are not proportional to the original dimensions. This means the image could be stretched or squished to fit the new dimensions.
