FAQ
Questions about Grayscale PDF
Why convert a PDF to grayscale?+
To cut file size, to proof how a document will look from a black-and-white printer, or to meet submission rules.
Can I increase contrast?+
Yes. The contrast slider darkens faint scans so text prints clearly.
Does text remain selectable?+
Pages are re-rendered as images, so text is no longer selectable. Run OCR afterwards if you need it searchable.
Are my files uploaded anywhere?+
No. Everything runs in your browser; your file never leaves your device.
