Frequently Asked Questions
How much can the file size be reduced?
Reduction depends on the PDF content. PDFs with large embedded images see the most benefit (30-80% reduction). Text-heavy PDFs with few images may see minimal reduction since text is already compact.
Does compression affect text quality?
No. Text and vector graphics remain untouched. Only embedded raster images are optimized. The text will remain perfectly sharp and searchable.
Can I compress password-protected PDFs?
No. The tool cannot process encrypted or password-protected PDF files. You need to remove the password protection first before compressing.
