About Compress PDF
Reduce PDF file size by compressing embedded images. This browser-based PDF tool is designed for quick document work such as preparing forms, reducing file size, extracting pages, or creating a shareable copy. Because the file is processed locally, it is a practical option for PDFs that include personal or business information.
