While Cloudinary doesn't restrict the length of a URL, there are some limits which should be taken into consideration when constructing the URLs.
- Different browsers define different limits to the length of URLs.
- The transformation string may not exceed the length of 1024 characters
If this constitutes a problem, one should consider using named transformations
- When fetching a remote image, its URL should not go above 255 characters (more information here). In such occurrences, you may prefer to explicitly upload the image by passing the remote URL as the "file" parameter to the upload method
