Real-World Compression Benchmarks
Unlike services that promise generic percentage reductions, real PDF compression depends strictly on the document type. Here are actual tested results using our client-side compression engine:
High Impact
Scanned 12-Page Invoice
Multi-page document with high-DPI full-page scanner images.
Original: 8.4 MB
Balanced (80%): 2.1 MB (-75%)
Max (60%): 1.4 MB (-83%)
Moderate Impact
Illustrated Slide Deck
Pitch deck containing charts, vector shapes, and photograph banners.
Original: 15.2 MB
Balanced (80%): 4.8 MB (-68%)
High Quality: 7.1 MB (-53%)
Technical Limitation
Vector Text-Only Contract
Pure text PDF with embedded fonts and zero photographs.
Original: 84 KB
Rasterized: ~180 KB (+114%)
Notice: Native text is already optimal!
How client-side PDF compression works and when to use it:
Our compressor runs 100% locally in your browser for absolute privacy. It renders PDF pages at the selected target resolution and recompresses embedded photographs and scanned artwork. For documents containing images, photos, or scanner pages, file sizes decrease by 40% to 80%.
If your PDF is pure text generated from Microsoft Word or Google Docs, it is already encoded as lightweight vector curves. In that scenario, image-based compression will rasterize text and may increase file size. If our tool detects no size reduction, we clearly notify you so you can keep your original vector file.

How Does PDF Compression Work?
Our PDF compressor uses advanced algorithms to reduce PDF file size by optimizing images, removing unnecessary metadata, and compressing data streams. This process maintains document quality while significantly reducing file size.
Compression Levels Explained
- Light (60%): Minimal compression, best quality
- Medium (40%): Balanced quality and size
- Heavy (25%): Maximum compression for smallest size
