Frequently asked questions
Will grayscale save printer ink?
It avoids printing colored inks when using a suitable monochrome print setup, but ink usage depends on your printer and settings.
Does grayscale guarantee a smaller PDF?
No. Size depends on images, fonts and how the PDF is rebuilt; use Compress PDF if file size is your main goal.
Can I still read text after conversion?
The output remains a PDF, but color-coded labels may be harder to distinguish once their colors become similar grays.
Are colorful photos converted too?
Yes. The conversion applies to page colors, including images and graphics.
How large can the input be?
Guests can upload files up to 25 MB each. A free account raises the limit to 50 MB per file, and Premium allows 500 MB per file with larger batches.
