How do I compress a PDF to under 100KB?

Upload your PDF, select "Extreme" compression level, and click Compress. Our tool can reduce most PDFs to under 100KB while maintaining readability.

Is my PDF secure when compressing?

Yes! ExactPDF processes all files locally in your browser. Your PDF never leaves your device - we never upload or store your documents.

Can I compress multiple PDFs at once?

Yes! Toggle "Batch Mode" to compress multiple PDF files simultaneously. All processing happens locally on your device.

Will compression reduce PDF quality?

You control the quality-size tradeoff. Choose from 4 compression levels: Low (best quality), Medium (balanced), High (good quality), and Extreme (smallest size).

Does this work offline?

Yes! Once the page loads, you can compress PDFs even without an internet connection since all processing happens in your browser.
