File Uploads

Need to let users upload files? You’re in the right place. PyView gives you a complete upload system with progress tracking, validation, drag-and-drop, and image previews—all wired up to work seamlessly with LiveView’s real-time updates.

You have two options for where files end up:

	Direct Uploads	External Uploads
Where files go	Your server	Cloud storage (S3, GCS, Azure)
Best for	Small files (<10MB)	Large files, high traffic
Server load	Higher (data flows through server)	Lower (browser → cloud directly)
Can pre-process?	Yes - transform, scan, validate	No - files go straight to cloud
Setup	Simpler	Requires cloud provider config

Where to Start

Direct Uploads — Start here. Upload files to your server with progress bars, validation, and drag-and-drop. This covers the most common use cases.

External Uploads — For large files or when you need to reduce server load. Files go directly from the browser to S3 (or similar) using presigned URLs.

Both approaches share the same template helpers and progress tracking—the difference is just where the bytes end up.
