So I was wondering , if I upload 260px * 260px and transform it to 1000px with I get some blur assuming the original image was High Q.

this question comes from 

I am trying to create a music app where users upload album arts , but I don't which size to send to Cloudinary.

  Hi Peters,

  Of course that it's best if the original image size is as close to the required delivered size.

  However, even if you do upload a smaller size image, you can use Cloudinary transformations to improve the image substantially - see example:

  Original:
  http://res.cloudinary.com/taladmoncloud/image/upload/test.jpg

  Width 1000px, no other transformation:
  http://res.cloudinary.com/taladmoncloud/image/upload/w_1000/test.jpg

  Width 1000px, apply e_improve, e_sharpen:
  http://res.cloudinary.com/taladmoncloud/image/upload/w_1000,e_improve/e_sharpen:400/test.jpg

  Please refer to our documentation for more transformations:

  Hi Peters,

  In the image http://res.cloudinary.com/taladmoncloud/image/upload/c_scale,w_1000/test.jpg the crop is scale (scale is the default cropping).

   

  You can read more about the crop option here:

  https://cloudinary.com/documentation/image_transformations#crop

   

  There is no difference between (the image is linked to a different transformation image):

  1.  http://res.cloudinary.com/taladmoncloud/image/upload/c_scale,w_1000/test.jpg

  2.  http://res.cloudinary.com/taladmoncloud/image/upload/w_1000/test.jpg
