Frequently asked questions
Will the text still be selectable?
No. Pages are redrawn as grayscale images, so the new PDF’s text can’t be selected or searched. Keep your original if you need that.
Will the file get smaller?
Often yes, but not always. Because pages become images, very text-heavy PDFs can come out larger.
Is PDF to Grayscale really free?
Yes. There is no signup, no watermark and no paid plan. The site is supported by ads.
Is my data sent to a server?
No. Your file is processed by code running in your browser. The page only downloads the open-source libraries it needs (for OCR, also the language data), never your file.
