HTTP 413 Content Too Large

What does HTTP 413 mean?

The request body is larger than the server allows. Formerly “Payload Too Large”. Nginx returns it when an upload exceeds client_max_body_size (1 MB by default), and PHP-based sites when upload_max_filesize or post_max_size is too small.

4xx Client error: The request has a problem the client can fix: wrong URL, missing credentials, bad data or too many requests.

Common causes of a 413 error

• Uploading a file larger than the configured limit.
• Nginx default client_max_body_size 1m.

How to fix 413 Content Too Large

• Compress or resize the file before uploading.
• Raise client_max_body_size in Nginx or LimitRequestBody in Apache, and PHP’s upload limits.
