Supports PDF files
Compress PDF files online to reduce their file size for easier uploading, sharing, and storage. DocuBlitz analyzes your PDF and applies compression automatically, making it easier to work with large documents without installing additional software.
Upload a PDF, let DocuBlitz process it, compare the resulting file size, and download the compressed document. The tool is free to use, requires no signup, and does not add watermarks to your PDF.
Compressing a PDF with DocuBlitz only takes a few steps:
PDF compression does not produce the same result for every document. The amount of reduction depends on how the PDF was originally created and what it contains.
A PDF that contains large images or other compressible data may become significantly smaller. On the other hand, a PDF that has already been optimized or contains mostly compressed content may show very little reduction. In some cases, processing can even result in a file that is slightly larger than the original.
For this reason, DocuBlitz shows the resulting file size so you can check the outcome before using the compressed document.
