Compressing a PDF for WhatsApp
WhatsApp can send large documents, but a big PDF takes longer to send and download on mobile data. This preset aims for under 1 MB.
Scanned pages shrink the most. Open the result and zoom in on small print before you send something important.
Frequently asked questions
Will the PDF still be readable on a phone?
Yes. At 1 MB most documents look the same on screen; check very small print before sending.
How do I make a PDF smaller?
Drop the PDF in. Quikdo re-saves the pictures inside it at a lower resolution and quality, which is where most of the size is. Pick a target like 200 KB if a portal has a limit.
How do I get a PDF under 200 KB?
Choose the 200 KB target before you drop the file in. Quality is lowered only as far as needed to get under it.
How do I convert a PDF from MB to KB?
Set a target in KB, such as 500 KB or 200 KB, and compress. A 3 MB scan often ends up a few hundred kilobytes.
