About Compress PDF
Reduce PDF file size. Choose smaller files for uploads or higher quality for printing.
How it works
- Choose a PDF file.
- Choose balanced, smallest-file or print-quality compression.
- Download the compressed PDF and check the size reduction.
Before you download
Already compact PDFs may not become smaller. Compression can reduce image quality, depending on your selected option.
Common questions
Why did my PDF stay the same size?
Some PDFs are already compact or contain little image data. If the processed file would be larger, the original file is returned.
Can compression affect image quality?
Yes. Stronger compression can lower image quality. Compare the preview before using the result for printing or submitting documents.
Does reducing PDF file size change its page dimensions?
Compression primarily adjusts embedded images and PDF streams. Use Resize PDF to change paper dimensions such as A4 or Letter, and Compress PDF to try to reduce the file size.
Can I request an exact PDF size in KB?
PDF compression offers quality profiles rather than an exact-byte target. The result depends on the document. Exact KB controls are available for photos and signature images; always check the reported size of your PDF result.
