Frequently asked questions
Is my PDF uploaded?
No. The file is processed locally in your browser.
Why can I no longer select the text?
Each page is re-rendered as an image to remove the colour, so the text becomes part of the picture.
Which resolution should I use?
150 DPI is fine for most documents. Use 300 DPI for small print you plan to print.
