Frequently Asked Questions
Is it safe to compress PDF files online?
Absolutely. Our PDF compressor processes your files **locally in your browser**. Unlike other tools, your sensitive documents are **never uploaded to any server**, ensuring 100% privacy and security.
How can I reduce PDF size for email attachment?
Simply upload your file to our **free PDF compressor**. You can set a **target file size** (e.g., under 25MB for Gmail) to ensure your document fits within email attachment limits.
Does compressing a PDF reduce its visual equality?
To significantly reduce size, our tool converts pages to optimized images. While this makes the file much smaller, it does mean **text becomes non-selectable**, but clarity is maintained for reading.
Can I compress PDFs offline?
Yes! Once this page loads, it works as an **offline progressive web app (PWA)**. You don't need an active internet connection to compress your files, making it perfect for working on the go.
Is there a file size limit?
There are **no strict upload limits** because processing happens on your device. However, for extremely large files (e.g., 100MB+), performance depends on your computer's memory (RAM).
