Compression SDK integration guide.

Overview

The Compression SDK is a compiled library distributed for .NET, Java, Node.js, and Go. Layout-preserving compression for PDF, TIFF, JPG, and PNG within PDFs. Designed for production server pipelines, multi-threaded, batch-capable, with predictable per-server licensing.

License + activation

The SDK is licensed per production server at per year. A site license at per year covers every server in one organisation, and OEM redistribution is available through sales. 3-year terms save 10%, 5-year terms save 20%; see the pricing page for the full breakdown. Activation is offline-capable for air-gapped environments, request an activation file from the portal.

All prices exclude tax. In India, GST is added at the prevailing rate.All prices exclude VAT, sales tax and any withholding tax.

.NET (C#)

dotnet add package Abscode.Compression

using Abscode.Compression;

var compressor = new PdfCompressor(licenseKey: "abs_comp_...");

var result = compressor.Compress(
    inputPath: "input.pdf",
    outputPath: "output.pdf",
    profile: CompressionProfile.Balanced
);

Console.WriteLine($"Reduced {result.OriginalSize} → {result.CompressedSize}");

Java

<dependency>
  <groupId>com.abscode</groupId>
  <artifactId>compression</artifactId>
  <version>1.0.0</version>
</dependency>

PdfCompressor compressor = new PdfCompressor("abs_comp_...");

CompressionResult result = compressor.compress(
    "input.pdf",
    "output.pdf",
    CompressionProfile.BALANCED
);

Node.js

npm install @abscode/compression

import { PdfCompressor } from "@abscode/compression";

const compressor = new PdfCompressor({ licenseKey: "abs_comp_..." });

const result = await compressor.compress({
  input: "input.pdf",
  output: "output.pdf",
  profile: "balanced"
});

Go

go get github.com/abscode/compression-go

Configuration

Format-specific notes

PDF

Compresses embedded JPG/PNG layers, removes redundant fonts and metadata, optimises stream encoding. Preserves text layer, form fields, annotations, and bookmarks.

TIFF (single + multi-page)

CCITT G4 for B&W scans, JPEG for colour. Multi-page TIFFs processed as a single document, page tags preserved.

JPG / PNG within PDFs

Embedded images downsampled per maxDpi and re-encoded at the configured quality level.

Server processing

The Server-side tier unlocks multi-threaded processing, batch pipelines, and DPI / size-cap controls. Thread count defaults to your CPU count; tune via threads option.

Batch pipelines

var batch = new BatchCompressor(licenseKey: "abs_comp_...");

batch.EnqueueDirectory("/incoming", "/outgoing");
batch.OnDocumentCompressed += (s, e) => Log(e.Filename, e.SavedBytes);
await batch.RunAsync();
