Frequently Asked Questions

What's the difference between Grayscale and True B&W?
Grayscale preserves all gray tones between black and white — ideal for photos. True B&W applies a threshold: each pixel becomes either pure black or pure white, which is great for sharp text documents.
Why would I want an Inverted PDF?
Inverted (white text on black) can reduce ink usage on some printer types and is easier on the eyes in dark environments. It's also useful for accessibility.
Does B&W conversion reduce file size?
In most cases, yes — grayscale and B&W images compress more efficiently than full-color ones. Exact size reduction depends on the PDF's content and compression settings.
Are my files uploaded anywhere?
Never. All processing runs in your browser using PDF.js for rendering and jsPDF for output. Your PDFs are completely private.
