Compress Scanned Invoice PDFs to Send via Email

Step by step

  1. 1

    Load Invoice PDF

    Add the multi-page scanned invoice PDF to the tool.

  2. 2

    Configure Compression

    Set DPI to 150 and enable Grayscale if colour is not required.

  3. 3

    Save and Attach

    Download the optimized PDF and attach it to your outgoing email.

Meeting Email Gateway Thresholds

Most email providers restrict attachments between 10 MB and 25 MB. Lowering the DPI to 100 or 150 brings multi-page invoice bundles well under standard gateway limits.

Grayscale Mode for Maximum Savings

For black-and-white invoices and paper receipts, enabling the Grayscale option removes unnecessary colour channels, producing an even smaller file size.

Frequently asked

Will item numbers and small figures remain readable?

Setting the quality between 65 and 80 retains crisp, readable text for numbers and line items while cutting down overall file size.

Can I select and copy invoice numbers from the compressed PDF?

No, the output PDF consists of rasterized page images, so text selection is disabled.
