Large PDF files can be cumbersome to share or store. This PDF Compression Tool reduces the file size while preserving quality, making PDFs faster to upload, email, or store.

How It Works

1. Upload Your PDF: Click the upload box or drag your PDF into it.

2. Preview Your PDF: The first page is displayed so you can confirm the file. The original file size is shown.

3. Compress the PDF: Click Compress PDF Now to reduce file size using optimized object streams and compression features.

4. Download Compressed PDF: After processing, the new file size and percentage saved are displayed. Click Download Compressed PDF to save it.

Features

• Instant Preview: See the first page before compression.

• Size Stats: Shows original size, compressed size, and percentage saved.

• Easy Download: One-click download of compressed PDF.

• Browser-Based: No server upload; everything happens in your browser.

• Safe & Secure: Files never leave your device.

Notes

• Compression depends on the PDF content (images, text-heavy, scanned pages).

• Object streams are used for compression; some PDFs with heavy encryption or unusual formats may compress less.

• For best results, avoid uploading extremely large PDFs (>100MB) in a browser environment.

This widget works seamlessly with PDF.js for preview and PDF-lib for compression, making it fully client-side and secure.
