FAQ

Frequently Asked Questions

How much can I reduce my PDF size?

Results vary depending on the PDF content. PDFs with many embedded images typically see 30–70% reduction. Text-only PDFs may see less reduction.

Will compression reduce PDF quality?

Low and medium compression maintain good visual quality. High compression reduces image quality more aggressively for maximum file size reduction.

Is this tool safe for sensitive documents?

Yes. Processing is entirely client-side in your browser. No data is transmitted to any server.

Why did my file not get smaller?

Some PDFs are already well-optimized or contain mostly text. In these cases the reduction will be minimal. Try the "High" compression level for maximum savings.
