Frequently asked questions
Why do some exam portals ask for a black and white PDF?
Black and white (grayscale) PDFs have a significantly smaller file size than color PDFs. Portals often mandate B&W to save storage space on their servers and ensure the document text is highly contrasted and readable.
Will this tool reduce the file size of my PDF?
Yes. By stripping the color data, the file size naturally decreases. The final PDF is also compressed to ensure it is optimized for web uploads.
Is it safe to upload my sensitive documents?
Absolutely. The conversion process is powered by your web browser. The document never leaves your computer, and we do not upload it to any cloud servers.
Does this tool work on scanned images inside the PDF?
Yes. It extracts every page of the PDF, applies a grayscale filter to the entire page (including all images and text), and repacks it into a new PDF document.
