Add one or more PDFs to compress
The PDF Compressor downsamples embedded image streams and optimizes font dictionaries to reduce heavy PDF documents down to email-safe sizes without sacrificing typography sharpness.
How to Use
Select any heavy PDF, scanned report, or slide deck exceeding email or portal limits.
Choose Recommended (70-80% savings), Strong, or Maximum compression while preserving text legibility.
Image stream downsampling at 150 DPI with crisp text vectors
Save your optimized document under target MB limits ready for email attachments and web forms.
Choose from our compression presets (Recommended, Strong, or Maximum). Scanned documents with embedded color images compress significantly (often 50% to 75% smaller) while retaining crisp text legibility.
Pure text and vector PDFs are inherently compact. Compression cleans unreferenced objects, optimizes font subsets, and strips duplicate resource streams to shave off extra kilobytes without rasterizing vector text.
The recommended compression profile balances downsampling with contrast preservation so that fine print, dates, signatures, and stamps remain sharp and readable on both screens and printouts.
If a PDF is already heavily compressed or consists primarily of pre-optimized monochrome vector outlines, additional compression yield is minimal because there is no redundant image data to strip.
