AdFrequently Asked Questions
Does compressing reduce PDF quality?
Our tool optimizes the PDF structure by removing redundant objects, enabling object streams, and compressing operators — without losing visual quality. For scanned/image-heavy PDFs, the reduction may be less than for text-based documents.
Are my files uploaded to a server?
No. All compression happens locally in your browser using pdf-lib. Files are processed in memory and never leave your device.
When can I download the compressed file?
Immediately after processing. The download button appears in the result area along with before/after file sizes.
