PDF Compressor Tool – Complete Description

Overview

The PDF Compressor Tool is a powerful, browser-based application designed to reduce the file size of PDF documents while maintaining optimal quality. This essential tool helps users compress large PDF files for easier sharing, faster uploading, and efficient storage. Whether you’re sending documents via email, uploading to a website, or managing a digital archive, this tool provides professional-grade compression with customizable settings to balance quality and file size.

How It Works

The tool uses PDF.js to render each page of your PDF document as high-quality images, then re-encodes them using jsPDF with adjustable compression settings. When you upload a PDF, you can choose from three compression levels: Low (best quality), Medium (balanced), or High (smallest file size). The tool processes each page, applies the selected compression, and generates a new, smaller PDF file. The entire process happens locally in your browser, ensuring your documents remain private and secure.

Key Features

1. Three Compression Levels

Choose from three presets to match your needs:

• Low: Best quality, minimal compression (90% quality)

• Medium: Good balance of quality and size (70% quality)

• High: Smallest file size with some quality loss (40% quality)

2. Real-Time Progress Tracking

A visual progress bar shows the compression status in real-time, keeping you informed as each page is processed.
