Reduce PDF size without flattening every page

FitPDF reduces eligible embedded images while preserving selectable text, OCR layers, vector graphics, fonts and page structure. Links, annotations, form fields and bookmarks are kept where the document allows it.

How to compress a PDF

  1. Choose your PDF and review what can be optimized.
  2. Select 2 MB, 5 MB, 10 MB or 20 MB, or type a custom file-size limit.
  3. Compress and download only after FitPDF checks the completed PDF.

If a target would require unacceptable quality loss, FitPDF reports the best safe result instead of claiming success.
