Question

Which js library can I use to upload files from any browser and will allow client-side restriction of the file size

Answer 1

Try jquery File Uploader

it has option

maxFileSize

The maximum allowed file size in bytes.

Type: integer Default: undefined Example: 10000000 // 10 MB Note: This option has only an effect for browsers supporting the File API.

But old browsers don't support this feature. And unlikely there are any way to fix it

Dropzone.options.myAwesomeDropzone = {
  paramName: "file", // The name that will be used to transfer the file
