Shrink PDF File Size Without a Subscription
Large PDFs — especially ones full of scanned images — can be too big to email or upload. PDF Compressor re-encodes the pages to reduce file size while keeping the document readable, with a choice between a balanced "Standard" setting and a more aggressive "Max Compression" mode for when size matters more than image sharpness.
How to use
- Upload the PDF you want to shrink.
- Choose "Standard" for a balance of quality and size, or "Max Compression" for the smallest possible file.
- Click "Compress PDF" and download the result once processing finishes.
Common use cases
- Getting a scanned document under an email attachment size limit.
- Reducing storage space used by an archive of PDF reports.
- Speeding up upload times for PDFs submitted through slow web forms.
