Good uses for a 500 KB PDF

  • Resumes and portfolios on job sites that cap uploads
  • College assignments and project reports
  • Email attachments that need to open fast on mobile data
  • Loan, property and insurance paperwork with several scanned pages

Clear photos at 500 KB

We pick a separate quality for every photo and check it with a visual quality score at normal reading zoom. That stops us from wasting bytes on paper grain and camera noise you would never notice, and lets us spend them on the ink, faces and charts you do notice.

Privacy by design

Your documents never touch a server

Bank statements, ID cards, contracts, medical reports. The files people compress are often the most private ones. So we built the tool to never see them.
