C# .NET APIs and Sample Codes for How to Compress TIFF Document



In this C# tutorial, you learn how to compress multipage TIFF image document and reduce TIFF file size in the C# ASP.NET web and Windows application through the following settings:

  • Compress a new created TIFF file
  • Compress and reduce an existing Tiff file size
  • Read an existing TIFF compression mode

How to compress multipage TIFF file using C#

  1. Download XDoc.TIFF Compression C# library
  2. Install C# library to compress TIFF image file

Overview



RasterEdge XDoc.Tiff for .NET utilizes the most advanced and standard based Tiff image and document compression methods, which guarantee C# users with high quality loss and lossless Tiff document compression. vb.net add text to pdf, convert pdf to word c#, how to read specific text from pdf file in c#, convert pdf to tiff c#, generate pdf azure function, c# wpf preview pdf. This C#.NET Tiff compressing SDK provides several industry standards and alternative compression options & technologies to compress Tiff image file, including Fax, Group4, JPEG, RLE(CCITT modified Huffman RLE), Zip, LZW, and Deflate.

This page mainly talks about Tiff image compression and specifically speaking, we support following two kinds of interfaces for Tiff document compression no matter for C# Windows project or C# ASP.NET web program.

  • When you create a TIFFPage with an image source, you can choose the type of image compression you want to use

  • When you create a new TIFFDocument with a collection of image source, you can specify one compression mode for all images or different modes for each





Tiff Image Compression Options using C#


You can compress a multipage tiff image file through option in ImageCompress. The below content lists all options which are applicable on TIFF document compression in C# code.


  • Uncompressed: No compression
  • CCITT1D: CCITT modified Huffman RLE
  • Group3Fax: CCITT Group 3 Fax encoding
  • Group4Fax: CCITT Group 4 Fax encoding
  • PackBits: PackBits compression (Macintosh RLE)
  • LZW: LZW (Lempel-Ziv & Welch) compression
  • JPEG: JPEG (Joint Photographic Experts Group) compression




How to compress a TIFF image file using C# code?


The text and C# source code below shows how to compress a multipage tiff image with PackBits compression using C# in your ASP.NET MVC, Windows application.



  1. Create a Bitmap object with an existing png image file loaded

  2. Create a new TIFFDocument object with the Bitmap object and image compression option ImageCompress.PackBits

  3. Save the Tiff object to a new file with PackBits image compression applied

String inputFilePath = "C:\\1.png";
String outputFilePath = "C:\\output.tif";

//  Get a Bitmap object
Bitmap image = new Bitmap(inputFilePath);

//  Create a single page TIFF document from the source image.
//  Use PackBits compression.
TIFFDocument doc = new TIFFDocument(new Bitmap[1] { image }, ImageCompress.PackBits);

//  Save TIFF document to a new file.
doc.Save(outputFilePath);








Common Asked Questions

What compression for TIFF?

Using C# TIFF library, TIFF image files can choose no compression or use one of the image compression algorithms below
  • Uncompressed: No compression
  • CCITT1D: CCITT modified Huffman RLE
  • Group3Fax: CCITT Group 3 Fax encoding
  • Group4Fax: CCITT Group 4 Fax encoding
  • PackBits: PackBits compression (Macintosh RLE)
  • LZW: LZW (Lempel-Ziv & Welch) compression
  • JPEG: JPEG (Joint Photographic Experts Group) compression
In C# class, you can apply the TIFF image compression through class ImageCompress.

How to compress TIFF files without losing quality?

You can easily compress TIFF images without losing image quality, use LZW to compress images in TIFF file. Using C# TIFF library, you can apply LZW image compression through class ImageCompress.

What is the best resolution for a TIFF file?

It depends on the TIFF file intended usage. 300 DPI or 600 DPI are standard resolution for high quality images for printing or file storage.

Should you compress TIFF files?

We recommend you to compress TIFF files. You can choose LZW to compress and reduce TIFF image file size without losing image quality. However for certain situations, you may not want to compress TIFF file. Using RasterEdge C# TIFF library, you can easily generate TIFF image file with or without image compression through options in class ImageCompress.

How do I reduce the size of a TIFF file without losing quality?

Choose a lossless image compression (like LZW or ZIP) during TIFF file generations. Using XDoc.TIFF C# library, you can easily generate TIFF image file with lossless image compression applied in C# ASP.NET Core, MVC, WinForms, WPF web and desktop applications.

What is LZW compression for TIFF?

LZW is also known as Lempel-Ziv-Welch compression. It is a lossless image compression technique that reduces file size without reduction in the quality of the image. One drawback of LZW compression is that compressed files without repetitive information can be large. Using XDoc.TIFF C# library, you can compress TIFF image file using LZW compression during TIFF generation or conversion through class ImageCompress.

Is TIFF ZIP compression lossless?

Same as LZW compression, TIFF ZIP compression is a lossless image compression. It will reduce TIFF file size without reduction in the quality of the image.
