Why convert to grayscale?

Smaller files, cheaper black-ink printing, easier reading in dim light, accessibility for color-blind users, and a uniform look for archives.

Does grayscale make the file smaller?

Often yes — color images become 3x smaller as grayscale. Vector text doesn't shrink much, since it's already monochrome data.

Will text quality suffer?

No. Text is rendered as grayscale at the same resolution.

Yes. Conversion runs entirely in your browser.
