Why convert to grayscale in your browser?
Whether it is a contract for the printer or a scan you want neutral, converting locally keeps the document on your device instead of uploading it to an online converter.
Frequently asked questions
Will the text stay selectable?+
No. Forcing a whole PDF to grayscale converts pages to images, so text becomes part of the picture. Use a higher DPI to keep it crisp.
Is my file uploaded?+
No. The conversion runs in your browser, so your PDF never leaves your device.
Why convert to grayscale?+
Grayscale documents are cheaper to print, often smaller, and avoid color-mismatch surprises.
Does it work offline?+
Yes. After the first visit it keeps working with no connection, because all processing is local.
