What is PDF Compression?
PDF compression reduces file size so documents are easier to email, upload, and store. How much you can shrink a file depends on images, fonts, and how the PDF was created.
How to Compress PDF Online
- Upload your PDF.
- Pick low, medium, or high compression.
- Click Compress PDF and review the size comparison.
- Download the compressed file or reset to try another document.
Compress PDF to a Specific Size
Targets like 100 KB or 200 KB are common for email attachments or upload limits. Results vary: image-heavy PDFs shrink more than text-only files. Try high compression first; if you still need a smaller file, use an image compressor on embedded images or split the PDF into parts.
