Will converting to black and white reduce my PDF file size?

File size changes vary depending on the original document. Some PDFs may be slightly larger due to image re-encoding, while others with heavy color gradients may be smaller. The tool shows before and after file sizes for comparison.

Does this tool preserve the quality of text in my PDF?

Yes, the tool uses a luminosity-based grayscale conversion method that preserves text clarity and readability. Text remains sharp and legible after conversion to black and white.

Can I convert scanned PDF documents to black and white?

Absolutely. The tool works with any PDF file, including scanned documents. It converts all visual content (text, images, graphics) to grayscale regardless of the source.

What is the luminosity method used for conversion?

The luminosity method uses a weighted formula (0.299 Red + 0.587 Green + 0.114 Blue) that accounts for human eye sensitivity to different colors, producing more natural-looking grayscale images compared to simple averaging.

Is there a limit on the number of pages I can convert?

There is no page limit, but the tool supports PDF files up to 100MB. Most multi-page documents fall well within this limit and process quickly in your browser.

Are my PDF files uploaded to a server?

No, all processing happens locally in your browser. Your PDF files never leave your device, ensuring complete privacy and security for sensitive documents.
