Frequently Asked Questions
Everything you need to know about our free PDF compressor.
Yes, completely free. There is no hidden cost, no subscription required, and no premium tier needed for basic compression. You can compress as many PDFs as you need, as often as you like, at no charge.
Absolutely. Your privacy is our top priority. Files are processed entirely on our secure servers, transferred over encrypted HTTPS connections, and permanently auto-deleted immediately after you download your compressed file. No staff member ever views your documents. We have zero data retention.
Compression results depend on your PDF's content. PDFs containing many images (photos, diagrams) can typically be reduced by 60–90%. Text-heavy documents such as reports or legal contracts typically see 20–50% size reduction. The "Low" compression level produces the smallest files, while "High Quality" prioritises maintaining visual fidelity.
Our "Medium" compression level produces excellent quality suitable for on-screen reading, email, and most print applications. The "High Quality" setting minimises quality loss while still reducing file size. If maintaining maximum quality is essential (e.g., for professional print), choose "High Quality".
You can upload PDF files up to 50MB in size. The vast majority of everyday PDFs — reports, invoices, presentations — fall well within this limit. If you regularly work with very large files, please contact us about enterprise options.
