Frequently Asked Questions

How does client-side PDF compression work?
The tool operates directly in your browser using local PDF rendering and stream recompression. It reduces file size by downsampling embedded images, stripping duplicate fonts and unneeded metadata, and optimizing page streams without uploading your files to any external server.
What is the difference between Visual Rasterizer and Lossless modes?
Visual Rasterizer re-renders pages as optimized high-DPI images, yielding the maximum size reduction for scanned documents, presentation slides, and image-heavy PDFs. Lossless Object Optimization cleans redundant internal PDF objects and streams while keeping text selectable and vectors sharp.
Are my confidential documents safe when compressing?
Yes, 100% private. All processing takes place in your local browser memory. Neither your PDF pages, text, nor metadata are transmitted over the network or stored on any server.
Will compressing my PDF degrade its visual quality?
You have granular control over the quality slider (DPI and JPEG quality). Standard settings (150 DPI, 65% quality) achieve drastic file size reduction (often 50% to 80%) while keeping text crisp and clear for printing or email attachments.
