Frequently Asked Questions

How much can I compress a PDF?

Our compression tool can reduce PDF file size by up to 90% depending on the original content. PDFs with many images typically see larger reductions, while text-heavy documents may compress less but still achieve significant size savings. The exact compression ratio depends on factors like image quality, embedded fonts, and document complexity.

Is it safe to compress PDFs online?

Yes, our PDF compression is completely safe and secure. All files are processed using client-side technology, meaning your documents never leave your device. We use advanced encryption during processing and automatically delete any temporary files. Your privacy and document security are our top priorities.

What's the difference between lossy and lossless compression?

Lossless compression reduces file size without any quality loss, perfect for documents with text and simple graphics. Lossy compression achieves higher compression ratios by slightly reducing image quality, ideal for PDFs with many photos. Our tool automatically selects the best method based on your document content to optimize both size and quality.
