Don’t rely on the Content-Type header or file extension alone. Use “magic number” detection (checking file signatures) or libraries like Apache Tika to verify the true content. For images, attempt to re-encode them with GD or ImageMagick.

That spring, the rains came hard and fast. Pip, growing in the rich soil, shot up two feet. His needles were lush and vibrant. Verruco, growing on the limestone slab, barely grew an inch. Pip felt superior.
To solve this, applications split large files into smaller pieces (chunks) of uniform size (e.g., 5MB each). The browser uploads these chunks sequentially or concurrently. If chunk number 42 fails due to a network glitch, the application only needs to retry that specific 5MB chunk rather than restarting the entire file. Once all pieces arrive, the server merges them back into the original file. The TUS Protocol High in the Rocky Mountains of Colorado, there
For large files (like videos), split the file into smaller pieces (chunks) on the client side. Upload them sequentially. If the connection drops, the application only needs to re-upload the failed chunk rather than restarting the entire file. Summary Checklist for Developers
This article dives deep into everything you need to know about file uploads: from basic HTML forms to advanced chunked uploads, security pitfalls, UX best practices, and emerging standards. By the end, you’ll have a roadmap to build (or improve) upload functionality that delights users and protects your infrastructure.
