Engineered for Developers

The High-Performance PDF Compression API That Just Works.
Integrate in Minutes.

The high-performance PDF compression API engineered for maximum file size reduction, sub-second latency, and zero downtime in your application stack. Focus on code, not compression complexity.

The Bottleneck

Large PDF files are a critical bottleneck. They slow down application uploads, inflate storage costs, drag down page load speeds, and ultimately degrade the user experience you worked so hard to build. Manually optimizing them is a time sink you can't afford.

The PDF Squeezer Solution

PDF Squeezer provides proprietary, highly optimized compression algorithms delivered as a simple, powerful REST API. We handle the complexity of object-level optimization, image downsampling, and metadata scrubbing, so you only have to worry about one thing: making the API call.

Build Better Applications.

Max Compression Ratio

Our proprietary engine delivers massive file size reductions (up to 80%) without visible degradation.

🚀

Sub-Second Latency

Globally distributed endpoints optimized for speed, ensuring real-time application responsiveness.

💻

Simple REST Integration

One clean, predictable endpoint. Integration is a matter of copy-pasting a few lines of code.
