Building a profile picture uploader is a common requirement for modern web applications, where users expect a smooth and visually engaging experience. For this project, your goal is to create a profile picture uploader that meets several essential requirements: you must allow the user to select an image file, provide an instant preview of the selected image, restrict uploads to specific file types (such as JPEG and PNG), enforce a maximum file size, and give users clear feedback if their file does not meet these criteria. A user-friendly uploader not only improves the experience but also helps prevent errors and confusion, ensuring that users can confidently update their profile pictures.

This uploader addresses all the core requirements for a robust profile picture upload experience. The HTML includes a single file input for the profile photo, and the CSS styles the uploader for a clean, centered appearance. The FilePond library is initialized with three key plugins: the image preview plugin displays a real-time preview of the selected picture, the file validate type plugin restricts uploads to PNG and JPEG images, and the file validate size plugin ensures that files cannot exceed 2MB. The configuration options control the allowed file types, maximum size, and user-facing labels. When a user selects a file, the onaddfile callback checks for errors and updates the feedback area if needed. If the user tries to upload an unsupported file type or a file that is too large, FilePond provides immediate feedback through the onwarning callback, which is displayed in the feedback area below the uploader. The preview appears instantly, giving users visual confirmation of their selection. Removing the file clears the feedback, keeping the interface tidy and user-friendly. This setup delivers a polished, reliable profile picture uploader that guides users at every step, prevents invalid uploads, and makes the process intuitive.
