Usage:
Upload a file:
curl -F file=@yourfile.ext {base_url}/
Shorten a URL:

Details:
Files uploaded to this service are stored for {expiration_days} days or until they are automatically cleaned up.
The maximum file size is {max_file_size}MB.
URLs shortened with this service will redirect to the original URL for the same period.
Examples:
