Grayscale PDF

Questions, answered
Does text stay sharp?
Yes. We convert with Ghostscript, which changes colours without turning pages into pictures, so text stays selectable. Photos become greyscale too, and the file often gets a little smaller.
Does this count toward my daily limit?
Yes. This tool needs a real engine on our servers, so each file counts as one conversion toward your daily limit. You get a free allowance every day, with or without an account, and Pro and Business raise it a lot.
What happens to my file after it's processed?
Your file is sent over an encrypted connection, processed, and returned to you straight away. We don’t keep a copy: temporary working files are deleted the moment the conversion finishes, and nothing is stored afterwards.
