What this tool does
Reduce scanned PDF size with JPEG downsampling. Choose resolution and quality; keep the original when it is already smaller.
Your file is sent to this site for the selected conversion and is processed for this request.
Scanned documents and photo-heavy PDFs often contain more image detail than a recipient needs for on-screen reading. This compressor renders each page at your chosen resolution and stores it as a compressed JPEG inside a new PDF. Lower resolution and quality can reduce size, but also make small writing harder to read. Inspect the downloaded result before using it for an application or sharing important records.
