Frequently Asked Questions
1Why convert a PDF to grayscale?
Grayscale PDFs use less ink when printing and result in smaller file sizes. Ideal for draft printouts and archival copies.
2Can I convert specific pages only?
Currently, all pages are converted. For selective conversion, split the PDF first, convert, then merge.
3Does grayscale conversion reduce file size?
Yes. Removing color data typically reduces file size by 30–60%, depending on the amount of color content in the original PDF.
4Will text remain readable after conversion?
Yes. Text clarity is fully preserved — only color values change. Black text stays black and remains perfectly sharp.
5Is the conversion reversible?
No. Once color information is removed, it cannot be restored. Keep the original file if you may need the color version later.
6Can I convert a color-scanned document to grayscale?
Yes. Both digitally created and scanned PDFs can be converted to grayscale.
