How It Works

Step 1: Upload Your PDF

Add the PDF in your browser. ExactPDF does not upload the file to a conversion server for this workflow.

Step 2: Use the 1MB Target

The page opens with the 1MB preset selected, so the compressor can search for the best achievable output around that portal limit.

Step 3: Download or Adjust

Download the result if it is readable and under the cap, or switch to 2MB, split pages, or PDF to JPG when 1MB is too strict.

Why Use This Tool

  • Built for portals, HR systems, forms, and email flows that reject files above 1MB
  • Reports the final size honestly instead of pretending every PDF can hit the target
  • Keeps private documents in the browser for the free workflow
  • Links directly to stricter and larger size limits for fast recovery when one target fails

Common Use Cases

Use the 1MB compressor for resumes, scanned certificates, signed forms, university documents, HR packets, insurance uploads, and email attachments where the receiving system blocks larger PDFs. If a scanned file becomes unreadable at 1MB, split unneeded pages first or use a 2MB target rather than submitting a damaged document.
