There is no SharePoint default permission level which allows add/edit but not delete existing files.
You need to create a custom Permission level in SharePoint. This will be a copy of your existing permission level minus Delete Items permission. Follow below steps to achieve this:

@ganeshsanap I set up a custom permissions site and only check marked the: Edit Items - Edit items in lists, edit documents in document libraries, and customize Web Part Pages in document libraries. The delete options are not check marked. This still gives users the option to delete webparts, unfortunately. Is there anything I'm doing wrong or is this just a Microsoft bug?

@ganeshsanap These instructions are not correct or helpful at all.
No, this is exactly what you will need to do.
As @ganeshsanap explained:
Create a new Custom Permission Level and remove the "Delete Items" / "Delete Versions" Permission from the level.
Assign that permission level to every user
The effect is that users can edit/create Documents in that Document Library, but are not able to delete them.
Keep in mind that users can still edit documents and Site Pages containing webparts are also just documents (and the permission level does not keep you from i.e. removing chapters from a word Document).
Also keep in mind that Site Collection Administrators are not affected by permission levels and will still have delete-permissions.
If you want to have a solution that even prohibits site collection administrators from deleting files or if you want to use the solution on more than one site collection (or your whole tenant), you should take a look at Retention Labels
But this is can only tenant-wide be done by an administrator.

@pweber1185 Do you know any other way to achieve what OP asked for? If yes, you can shared it with community members here.
You have to create a custom permission level for this requirements. Steps might not be accurate based on which experience you are using (modern or classic).
You can go to advanced permissions settings page of site collection using URL in below format and create a new permission level as per your requirements and then use it to grant permissions to groups/users:

Hi @ganeshsanap ,
I also want the user to not be able to delete files. But after I did this step, it's true that the user can't delete it anymore. However, the user also cannot rename files, give file names when creating files, and cannot move files to other folders. Is it really like that?

@IrvanR Unfortunately, this is by design in SharePoint. In order to rename or move files, you need delete permissions on the files / document library.
