Client-Side Optimization Engine

Frequently Asked Questions
Does compression affect document quality?
Under the Recommended setting, text formatting and layout elements remain completely crisp while images are optimized. Under Extreme compression, image resolution may decrease slightly to maximize size savings.
Is there a limit on input file size?
No. The only boundary is your device's system memory (RAM). Browsers on modern laptops and smartphones can easily optimize PDFs of 100MB or larger.
