Is there any way to change file size to allow me to upload a file?
You can't change these settings in SharePoint online.You can change the file size upload limit in an on-premises environment, but it's not possible in SharePoint Online because it's a shared setting for all the tenants.
We are Getting error trying to upload 48 MB files.
I don't think you have got an error due to the file size, the 48Mb is not reached to the supported size limit. Moreover, you should be able to upload a file from the browser with a size up to 10 GB as I mentioned above.
So should you please tell us
- What's the type of your error specifically?!,
- Are you trying to upload the file from SharePoint or another third party program or programmatically? if yes kindly check increasing file size limit for Sharepoint online for uploading files through SharePoint web service
