Frequently asked questions
How do I compress a PDF to 50 KB?
Upload the PDF, keep the 50 KB target, tick grayscale for a black-and-white document and press Compress. The result panel shows the exact size reached.
My PDF will not go below 50 KB.
Usually because it is a colour photo scan or has several pages. Tick grayscale, remove pages the form did not ask for, or crop the margins with Crop PDF, then compress again.

For a one-page certificate in black and white, yes. Zoom in on the result before uploading to check the certificate number and seal.
