PDF Compressor
Reduce PDF file size
The essentials
The PDF Compressor reduces oversized PDFs by rebuilding pages at an optimized resolution — turning email-bouncing files into lightweight documents.
How to use it
- Upload the PDF you want to shrink.
- Pick a compression level.
- Compare the size reduction.
- Download the smaller PDF.
Pro tips
- Scanned documents compress the most — often 70–90% smaller.
- Text-heavy PDFs compress less; try the target-size tool for exact limits.
- Compression rebuilds pages as images, which removes selectable text — keep the original if you need search or copy.
Behind the result
Compression rebuilds each page as an optimized image at your chosen level and reassembles the PDF. This shrinks scan-heavy documents dramatically — but pages become images, so selectable text and links are removed.
A worked example
A scanned 12 MB contract bounces back from email.
- Input
- A 12 MB scanned PDF of 20 pages.
