Frequently Asked Questions
How does client-side PDF compression work?
The tool parses the PDF, renders high-resolution page canvas templates, and recompresses embedded graphic components before packaging them back into a clean, smaller document.
Will my PDF text remain searchable?
Yes, standard vector text and document structures are preserved. Only embedded raster images are compressed to optimize size.
