About this tool

First tries a lossless-style structural cleanup (rewriting the document with tighter object streams). If that isn't small enough, it re-encodes pages at progressively lower JPEG quality to find the largest result that fits your limit. It never returns a larger file than you started with.

Application PDFs — scanned certificates, mark sheets, declarations — are often several MB when the portal allows only a few hundred KB. This targets your exact limit while keeping quality as high as possible.

Key capabilities

  • Target any max KB from your portal
  • Structural cleanup first, then image re-encoding
  • Keeps best quality that fits
  • Never ships a file bigger than the original
  • Entirely local processing
