How to use Compress PDF
Reduce the size of image-heavy PDF files so they are easier to email, upload, and store. Text remains readable while embedded images are optimized.
- Add the PDF you want to reduce.
- Choose a compression level.
- Compare the result and download the smaller file.
When this tool is useful
Compression is most effective for scanned documents and presentations. Text-only PDFs may already be close to their smallest practical size.
