Compressed PDF

Free Online PDF Compressor

Reduce the size of your PDF files instantly with FreePDFSnap's free PDF compressor. Large PDFs are slow to email, hard to upload, and take up unnecessary storage. Our tool compresses PDFs by optimizing embedded images while keeping the document readable.

Why compress a PDF?

Email attachments have size limits, websites require small uploads, and large PDFs are slow to open on mobile devices. Compressing your PDF can reduce its size by 30-80% depending on the content.

How to compress a PDF

  1. Drop your PDF file in the upload area above
  2. Choose a compression level (Medium is recommended)
  3. Click "Compress PDF" and download the smaller file

Will quality be affected?

Our "Low" compression setting preserves near-original quality. "Medium" is recommended for most use cases. "Maximum" produces the smallest file but may reduce image sharpness inside the PDF.
