FAQ
Does converting to grayscale make the file smaller?
No. The grayscale effect comes from a layer added over each page, and the original colour data stays in the file. To reduce the file size, use “Compress PDF”.
Is my file uploaded?
No. The conversion runs in your browser and the file never leaves your device.
