Frequently asked questions
Why convert to grayscale?+
Black-and-white PDFs print more cheaply on colour printers and produce simpler, smaller files for text documents.
Will the text still be selectable?+
No. Pages are rebuilt as grayscale images, so selectable text is removed. Keep your original if you need to edit it.
Are my files uploaded to a server?+
No. Every PDFini tool runs entirely in your browser using JavaScript. Your files are read and processed on your own device and are never uploaded, stored or seen by us.
