Frequently Asked Questions
Is it safe to compress PDFs here?
Absolutely. We use advanced browser-based technology (WebAssembly) to process your files directly on your device. Your PDF documents never leave your computer and are never uploaded to any server.
How much can I compress my PDF?
The amount of compression depends on the content of your PDF (images, text, fonts) and the compression level you choose. 'Extreme Compression' can reduce file size significantly (up to 80-90%) but may reduce image quality.
Do you support scanned PDFs?
Yes! Our tool works great with scanned documents. It optimizes the images within the scan to reduce the overall file size.
Will my text remain selectable?
To achieve maximum compression securely in the browser, this tool may flatten pages into high-quality images. This works best for scanned documents or files where visual fidelity is more important than text selection.
