Size limit for file upload
html, javascript
Solution
Nope, there is no size upload limit.
here is the spec and here is a related question on how to check the file size, so that you can add limits if you like.
It's worth pointing out that if you are looking to store the file on the server, you might hit file upload limits/restrictions there. But you should be able to configure them. i.e. php/wordpress default upload limit
Problem
I investigate the problem of file upload using html5, and I have theoretical question: has html5 any limits for file size for uploading? For example, can I upload files with size ~500Gb? P.S.: I use FileReader api for reading file. Ok. This problem is resolved. But as it explains in FileReader API: This interface provides methods to read File objects or Blob objects into memory... As I understood correctly, I can't read file with size which is more than available RAM?
