How Does PDF Compression Work?
PDF compression is a smart process. It doesn't just randomly delete data. Instead, it intelligently identifies and removes redundant information, downsamples high-resolution images to a web-friendly resolution, and optimizes the file's internal structure. As explained by the creators of the format, Adobe, a good compressor can significantly reduce PDF file size while keeping the text sharp and images clear.

Frequently Asked Questions (FAQs)
1. Is it safe to use a free PDF compressor?
Yes, with a trusted provider. At Gollari Studio, your security is paramount. We use SSL encryption to protect your files during upload and download. More importantly, your files are automatically and permanently deleted from our servers one hour after processing. We never look at, copy, or share your content.
2. Will compressing a PDF file badly affect its quality?
Not necessarily. Our tool is designed to provide the best possible balance. For documents containing mostly text, the quality will look virtually identical. For PDFs with many images, our 'Basic Compression' will maintain excellent visual quality while still achieving significant size reduction. 'Strong Compression' is more aggressive but is perfect for when size is more critical than image fidelity.
3. Can I compress a password-protected PDF?
No, for security reasons, you cannot directly compress an encrypted or password-protected PDF. You must first remove the password. If you own the file and have the right to modify it, you can first use our Unlock PDF tool and then proceed to compress the unlocked version.
