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 (or less frequently used - incoming transformation).
- When fetching a remote image, its URL should not go above 256 characters (more information here). In such occurrences you may prefer to explicitly upload the image.
