Reduce PDF Size Online
Reduce the file size of your PDF documents to meet email attachment limits, speed up uploads, and save storage space. The compression tool works entirely in your browser for complete privacy.
Step-by-Step Guide
Add your PDF file
Upload the PDF whose size you want to reduce.
Select reduction level
Choose how much to reduce: light (minimal quality impact), balanced, or maximum (smallest file).
Process the reduction
The tool compresses your PDF and shows the size reduction percentage.
Download the smaller PDF
Save the reduced PDF. It is ready to email, upload, or archive.
Tips
Most email services limit attachments to 25 MB. Use this tool to get your PDF under that limit.
Scanned documents often have unnecessarily large file sizes and compress very well.
If you need to reduce size further, consider splitting the PDF into smaller parts.
The original file is never modified. You always get a new, smaller copy.
Frequently Asked Questions
Why are my PDFs so large?
Large PDFs usually contain high-resolution images, embedded fonts, or scanned pages stored as images. Compression reduces the image data while keeping the document readable.
Is the reduced PDF still printable?
Yes. Even with high compression, PDFs remain perfectly printable. Text is unaffected, and images are compressed but still clear enough for printing.
Can I reduce the size of a scanned PDF?
Yes, and scanned PDFs often see the biggest size reductions since they are essentially large images. Expect 40-70% reduction with balanced compression.
