Frequently Asked Questions

How do I increase the upload limit?
It depends on your server. For nginx: client_max_body_size in nginx.conf. For Apache: LimitRequestBody directive. Also check your application framework's limits and any CDN/proxy limits.
What's a reasonable maximum upload size?
It depends on your use case. Common defaults: 1MB for API payloads, 10-50MB for file uploads, 100MB+ for video uploads. Set limits based on your actual needs and server resources.
