FREQUENTLY ASKED QUESTIONS
Is my PDF safe?
Yes — everything happens in your browser. Your PDF is never uploaded to any server. The file is processed entirely using JavaScript on your device.
How does compression work?
The tool rebuilds your PDF from scratch — stripping unnecessary metadata, flattening form fields, removing duplicate objects, and optionally resizing pages. This can significantly reduce file size, especially for PDFs with bloated metadata or embedded fonts.
Will it reduce image quality?
This tool does not re-compress images. It optimizes the PDF structure itself. For PDFs with large embedded images, the savings come from metadata removal and structural optimization. Image-heavy PDFs may see smaller reductions.
What's the maximum file size?
Since processing happens in your browser, it depends on your device's available memory. Most devices handle PDFs up to 50–100 MB without issues.
