413
Universal HTTP Status Code
Severity: ModerateWhat Does This Error Mean?
A 413 Payload Too Large error means the file or data you are trying to send to the website is bigger than the website allows. Every server has a limit on how much data it will accept in one request. You have exceeded that limit. This is most common when uploading files — photos, videos, documents, or attachments. The server is not broken — it is simply enforcing a size cap.
Affected Models
- All web browsers
- File upload websites
- Email attachment systems
- Web applications
Common Causes
- The file you are trying to upload exceeds the website's maximum allowed size
- You are submitting a very large form with too much data
- A video or high-resolution photo is too large for the website's upload limit
- You are trying to upload multiple large files at once
- The website's server has a low upload limit set by the administrator
How to Fix It
-
Reduce the file size before uploading. Compress images using a tool like TinyPNG (tinypng.com) or resize them to a smaller resolution.
A photo straight from a modern phone camera can be 10–20MB — often more than most sites allow.
-
For videos, use a free tool like HandBrake to compress the video before uploading.
Video files are the most common cause of 413 errors. Even small compression makes a big difference.
-
If uploading multiple files, try uploading them one at a time.
The combined size of multiple files can easily exceed the limit.
-
Check if the website states its file size limit. Look for help pages or upload instructions.
Staying under the stated limit is the simplest solution.
-
Consider using a file sharing service like Google Drive or Dropbox to share large files, then send a link instead of uploading directly.
This is often faster and avoids upload limits entirely.
When to Call a Professional
If you need to upload large files regularly and the website's limit is too low, contact the website's support. They may be able to increase the limit or offer an alternative upload method. Website owners should configure server upload limits to match their users' needs.
Frequently Asked Questions
What is the typical maximum file size websites allow?
It varies widely. Basic websites often allow 2–8MB. More capable platforms may allow 25MB, 50MB, or more. The website should state its limit — check the upload page or its help section.
Can I ask the website to increase the limit?
Yes — if you have a legitimate need, contact support. Many platforms allow higher limits for paid accounts or can make exceptions.
Is my file saved anywhere if the upload fails with a 413?
No — the server rejected the upload entirely. Your original file is safe on your device, but nothing was saved to the website. Compress the file and try again.
