Frequently asked questions
- How much can I reduce a PDF file size?
- Results vary by content. PDFs with many high-resolution images can shrink 50–90%. Text-heavy PDFs may see 10–30% reduction.
- Will compression make text blurry?
- Text is never affected by compression — only embedded images are optimized. Text remains perfectly sharp at any zoom level.
- Can I compress a PDF that is already small?
- Yes, though the reduction will be minimal. The tool will still optimize any redundant data it finds.
- Does compression remove pages or content?
- No. Compression only reduces the file size of existing content. No pages, text, or images are removed.
