Frequently Asked Questions
Which compression level should I use?
Use Light for text documents and already-compressed PDFs. Use Balanced for PDFs with photos. Use Maximum for scanned documents where smallest size matters most.
Are my files uploaded to a server?
No. PDF compression happens entirely in your browser. Your files are never sent to our servers.
Will compression reduce quality?
Balanced and maximum modes rebuild pages as JPEG images — great for scans, but not for text-only PDFs. Light mode preserves text and vectors.
Is this tool free?
Yes. TetraKits Compress PDF is completely free with no signup, subscriptions, or usage limits.
Smaller PDFs, Same Convenience
Large PDF files are hard to email, slow to upload, and take up storage space. TetraKits Compress PDF helps you shrink file size quickly while keeping control over the trade-off between quality and compression.
Everything runs locally in your browser, so your documents stay private and the tool works on any device.
