SNS send file attachment

Question

My one AWS hosted application need to  send PDF or DOC or JPG  any format files to http, SQS , https  type subscriptions through SNS. Is it possible? Can you please provide any AWS reference tutorial link related for this? If not possible what kind of AWS Service  will help me to achieve this  using Messaging Service. Thanks in advance

Answer

SNS is designed to send messages, it's not designed to send files (especially large ones). 
You can send Base64-encoded binary data object, considering the max message size of 256KB.

See https://docs.aws.amazon.com/sns/latest/api/API_MessageAttributeValue.html for details.

For larger payloads see the pattern described in  https://docs.aws.amazon.com/sns/latest/dg/large-message-payloads.html

Answer

SNS is a notification service and isn't built to send attachments. You can use the next pattern:
Put your file as an object in S3; Send notification in SNS with the pointer to the S3 object. 
You'll need to define the permissions for the bucket and the object.
