Does grayscale conversion reduce file size?

Often yes. Removing color information from images and graphics can reduce the file size, especially for image-heavy documents. For maximum compression, use the Compress PDF tool afterward.

Is the conversion reversible?

No. Converting to grayscale removes color information permanently. Keep a copy of the original color PDF if you need it.

Do my files get uploaded to a server?

No. The grayscale conversion is done entirely in your browser. Your PDF never leaves your device.

Will text remain sharp after conversion?

Yes. Text is rendered as black on white regardless of the original color, so it stays crisp and readable.

Can I convert only specific pages to grayscale?

The tool converts all pages. To convert specific pages only, extract those pages first, convert them to grayscale, then merge them back with the original color pages.
