What makes a PDF so large (75 Mo)?
A 75 Mo PDF typically contains high-resolution images, complex vector graphics, or embedded fonts. Scanned documents, presentations converted to PDF, and reports with many photos are the most common cases. The good news: these elements can be optimized without losing readability through smart compression.
Common document types
Professional reports
75 Mo reports with charts and tables compress very well.

Technical compression details
Our algorithm analyzes each component of your 75 Mo PDF: images (JPEG, PNG), fonts, metadata, and internal structure. Images are recompressed with an optimized ratio, fonts are subsetted (only used characters are kept), and redundant metadata is removed. Result: a reduction to approximately 15 Mo with no visible impact on document quality.
