About this tool

Pdf2Go compresses by re-rendering each page at a resolution and image quality you choose, then assembling those pages into a new document. That is very effective for scans and image-heavy exports. It is a lossy process: the result is a picture of each page, so selectable text becomes part of the image. Start at the balanced preset and only go lower if the preview still reads clearly.
