FAQ

Preguntas frecuentes

How does client-side PDF compression work?
The tool parses the PDF object graph, compresses cross-reference tables into object streams, and removes unnecessary metadata without altering document text or layouts.
Why did my PDF only shrink by a small amount?
PDFs that consist purely of plain vector text or that have already been pre-compressed by scanning software often cannot be reduced further without degrading text readability. We report this honestly rather than exaggerating results.
Is it safe to compress sensitive legal or financial PDFs?
Yes. Because our compressor runs entirely inside your web browser sandbox, no data is sent over the internet.
Can I compress password-protected PDFs?
You must remove password protection from the document before compressing it, as encrypted PDFs cannot be safely rewritten in-browser.
