This is a locally hosted web application that allows you to perform various operations on PDF files, such as splitting and adding images.

Started off as a 100% ChatGPT made application, slowly moving away from that as more features are added

I will support and fix/add things to this if there is a demand [Discord](https://discord.gg/Cn8pWhQRxZ)
