📌 How it works:
⚠️ This rasterizes vector PDFs into images, making text unselectable. Intended for scanned documents.
1️⃣ Enable multiple filters together; they are applied in a suitable processing order.
2️⃣ Convert color scans to black and white, improve sharpness and more, then save a new PDF.
⚠️ Processing converts pages to images, so text cannot be selected or searched.
