Reduce PDF size while managing quality
PDF compression can make documents easier to email, upload, and store. Results depend on the source: scanned and photo-heavy PDFs often shrink more than documents that already contain optimized text and graphics.
How to use this tool
- Choose the PDF you want to reduce.
- Select maximum, recommended, or low compression.
- Create the smaller file and compare it with the original.
Good uses
- Meeting an attachment or portal size limit
- Reducing photo-heavy scans
- Preparing lightweight copies for mobile viewing
Tips for a reliable result
- Start with Recommended for a balance of readability and size.
- Use Low compression for documents with fine print or detailed diagrams.
- Always inspect photographs, small text, and signatures at normal zoom.
Important limitation
Compression cannot guarantee a particular final size. PDFs that are already optimized may shrink only slightly, while aggressive settings can soften images.
File privacy
The PDF is processed to generate a compressed copy. Do not upload sensitive documents without appropriate permission, and keep your original unchanged.
Frequently asked questions
Why did my PDF barely shrink?
It may already use compressed images and efficient fonts, leaving little redundant data to remove.
Does compression change the original?
No. The tool creates a separate download; your local source file remains unchanged.
