What This Tool Does
The PDF Compressor is a browser-based utility designed to reduce the storage size of PDF documents. It works by analyzing the internal document structure, simplifying redundant visual assets, and compressing high-resolution embedded images without changing the text layout.
Why This Tool Is Included
Many online services require you to register or purchase a subscription to compress large documents. Singulariti operates differently. For tools that run fully in the browser, files can be processed locally without being uploaded to a server. This protects document privacy and eliminates server upload lag.
