Simple PDF Compression #

A Flutter package for compressing PDFs. This package provides a simple use but with a more complex algorithm to work out optimal compression ratios.

Features #

• PDF Compression: Compress PDF files with different compression levels
• Customizable: Configure compression parameters to suit your needs

Getting Started #

Add the package to your pubspec.yaml file:

flutter pub add simple_pdf_compression

or

dependencies:
  simple_pdf_compression: ^0.0.1

Then run:

flutter pub get

Usage #

import 'dart:io';
import 'package:simple_pdf_compression/simple_pdf_compression.dart';

void main() async {
  final inputPdf = File('/path/to/your/input.pdf');

  final compressedPdf = await compressPdf(
    inputPdf,
    thresholdSize: 500 * 1024, // Optional: 500 KB
    quality: 60,               // Optional: 0 (most compression) to 100 (lowest compression)
  );

  print('Compressed PDF saved at: ${compressedPdf.path}');
  print('Original size: ${inputPdf.lengthSync()} bytes');
  print('Compressed size: ${compressedPdf.lengthSync()} bytes');
}

Additional Information #

• The compressed files are saved to the temporary directory by default
• Without passing quality the quality of the PDF is worked out and IQR is used to work out an appropriate compression amount.
• Inspired by @rathorerahul586 package pdf_handler
