frequently asked questions
how is it converted?
each page is rendered, every pixel is converted to gray, and the pages are rebuilt as jpeg images with the original page size.
what is the downside?
text becomes part of the image, so it is no longer selectable or searchable.
is my pdf uploaded?
no. conversion happens in your browser with pdf.js and pdf-lib.
