Sorted by: Reset to default 5

I agree with TrueBlueAussie. This looks like a server side setting in PHP.

Open you php.ini file and find the line stating upload_max_filesize. The default it set to 2M, which is 2MB. Try increasing it to 3MB and see if you are still receiving the error.

Note: You'll need to restart Apache/Nginx/webserver for this to take affect from the php.ini file.

Even though you are sending the file as a variable, the application/x-www-form-urlencoded might be interpreted in PHP as being an actual file upload. The other php.ini setting you can take a look at will be post_max_size which has a default of 8M, which is the maximum that you can POST to your PHP script.

First of all: the code that you indicate in base64 returns a corrupted image; when you send the code in base64, uses the function encodeURIComponent to avoid errors when sending.

Try this code:
