Compress PDF to Exact Size - Complete Guide

Need to compress PDF to 100KB for a job application? Or reduce PDF to 1MB for email? Our free tool lets you compress PDF files to any exact target size - perfect for meeting strict upload limits.

Compress PDF to 100KB

Many government portals and job applications require PDFs under 100KB. Our tool uses smart compression to reduce PDF size to 100KB while keeping text readable. If your document has many images, you might need to try 200KB instead.

Compress PDF to 1MB for Email

Email attachment limits (Gmail: 25MB, Outlook: 20MB) mean you often need to compress PDF under 1MB or 2MB. Our tool makes this easy - just select 1MB as your target and compress. Perfect for sending multiple attachments.

How Target Size Compression Works

Unlike regular PDF compression that just reduces quality, our target size compression uses a smart algorithm:

  • Renders PDF pages as high-quality images
  • Iteratively compresses images at different quality levels
  • Rebuilds the PDF to match your exact target size
  • Maximizes quality within your size constraint

Tips for Better Results

To get the best results when compressing PDF to a specific size:

  • Remove unnecessary pages first using our Remove PDF Pages tool
  • Try larger targets if 100KB produces poor quality
  • Text-heavy PDFs compress better than image-heavy ones
  • Scanned documents may need larger target sizes

100% Private and Free

All compression happens in your browser. Your PDF files are never uploaded to any server - they stay on your device the entire time. No signup required, no watermarks, unlimited use.
