And what pdf toolkit do you use?
As a result, form fields typically aren't fillable after merging, and field name conflicts aren't an issue, so we don't rename fields.
We use @cantoo/pdf-lib (a maintained fork of pdf-lib) running entirely client-side in a Web Worker, so all processing happens locally in the browser and no files leave the user's device.
