File Upload System (Images, Docs) is a backend feature that allows users to securely upload, store, and manage files such as images, documents, PDFs, and other media types within an application.
The system handles file validation, including type checking, size limits, and security scanning to prevent malicious uploads. Once validated, files are stored either on cloud storage services (like AWS S3, Cloudinary, or Azure Blob Storage) or on a dedicated server, with proper file paths saved in the database.
It also includes features like file compression, thumbnail generation for images, access control permissions, and secure download or viewing links. A well-designed file upload system ensures reliability, scalability, and fast retrieval while maintaining data security and user privacy.
