Free PDF compression questions
Is PDF compression free?
Yes. It is free without an account or usage-count limit, and processing stays in your browser.
How do lossless and image compression differ?
Lossless mode keeps image data unchanged and may save little. Balanced and high-quality modes recompress JPEG images for greater savings.
Are text and form fields preserved?
The tool is designed to preserve searchable text, forms and links. Open the saved result and check important documents.
Why are signed and encrypted PDFs rejected?
Rewriting a PDF can invalidate a digital signature, while encrypted files require separate permission handling. This tool stops safely instead.
