How to compress a PDF to 500KB
1) Upload your PDF. 2) The 500KB target is pre-selected. 3) Download a file under 500KB.
Why 500KB?
500KB is a common cap for email attachments and government or job-application upload forms. Hitting a size — not a vague “quality” slider — is what actually gets your file accepted.
Keep it looking right
MarqPDF re-samples images and strips waste, but keeps text crisp, so your document is still readable at the smaller size.
