Gulag Cleaner

Gulag Cleaner is a tool designed to remove advertisements from PDFs, making it easier to read and navigate documents without being disrupted by unwanted ads.

This tool does not just crop the ads out of the PDF, instead, we extract the original file without ads by manipulating the internal structure of the PDF, ensuring maximum quality.

In addition to removing advertisements, Gulag Cleaner is also capable of extracting metadata, such as the author, subject, university, and more, from the file.

Web Version

This tool can be used without installation directly from our website (in Spanish).

Installation

To install Gulag Cleaner, please download and install Python and then run the following command in your terminal:

TODO

If you want to help, these are the top priorities right now:

• Find a way to sending the method code to JS in the WASM implementation. Serialization using Serde seems to fail for some reason.
• Add a README.md (With code examples) for the JS (wasm) distribution.
