About this tool
Reduce a PDF's file size so it is easier to email or upload where there's a size limit. Each page is re-rendered and re-compressed at the quality level you choose. This approach works best on scanned documents or PDFs full of images; a PDF that is already mostly plain text may not shrink much further.
How to use it
- Upload the PDF you want to shrink.
- Choose a compression level: high compression, balanced, or best quality.
- Click Compress PDF.
- Compare the before-and-after size and download the result.
Frequently asked questions
Why didn't my file get smaller?
Text-based PDFs are already compact. This tool compresses by re-rendering pages as images, which helps most with scanned or photo-heavy PDFs rather than typed documents.
