Why Convert PDF to Grayscale?
- Save Printing Costs — Black and white printing uses significantly less expensive ink and toner than color printing.
- Reduce File Size — Grayscale images contain less data than full-color ones, resulting in smaller, more shareable files.
- Archive Documents — Grayscale is the standard for long-term document archiving and legal submissions.
- Improve Accessibility — High-contrast black and white documents are often easier to read for individuals with visual impairments.
