Here is my version of this process and I'm getting similar results bug different: But this is a small price to pay for all the space you can save using TIFF image compression.I'm not sure, but for me it looks like Chris forgot to add some steps. When you have a large number of large files to process – the time can be significantly greater than processing images without any compression.
#Tiff compressor decompressor software
However, each time you save or open compressed TIFF files, the software you use will need some time to compress or decompress your images. What is not to like about having smaller files of absolutely the same quality as the big ones? You will see that both types of compression work great.
#Tiff compressor decompressor zip
Select a dozen images with completely different content and save them with both LZW and ZIP compression to see which results you like better. Street lamp: No compression – 16.5 Mb, LZW compression – 5.3 Mb. Roll of film: No compression – 20.7 Mb, LZW compression – 4.1 Mb. A person with a phone: No compression – 21.5 Mb, LZW compression – 9.8 Mb. Images with different content and their compression levels. Images with plain backgrounds and large areas of solid colors will be reduced in size significantly. Images with lots of details, rich textures, and high color depth may not compress very well. It is important to test multiple files because the level of compression is dependent on the image content. Both of this algorithms will produce different results for the same image, in most cases just slightly different.Ī good way to see the difference in file size reduction between LZW and ZIP is to use both these options on various types of images and compare the results. But the question is which is better? Because the quality of the image is unchanged, the best algorithm, in this case, will be the one that produces the smallest files.
So, you can safely use either LZW or ZIP compression. The file size should be smaller than with TIFF. If you don’t mind a little quality reduction and just want smaller file sizes, you may as well save the images as JPGs. On a personal note, I don’t see a reason to save TIFFs with JPEG compression. This process is irreversible because some data from the original image file is stripped out and lost forever each time you compress the image. Moreover, each time you resave your TIFF file with JPEG compression, even when the quality level is the same, the file gets smaller and you are losing quality. This is similar to compressing other file formats with ZIP archiving software – all information is there but the file is just smaller.Ĭontrary, JPEG is a lossy compression algorithm which will result in image quality reduction, although it may not be noticeable with the bare eye. This process is reversible and the image can be resaved with a different compression algorithm or without any compression with the same quality as the original. You may wonder which is better, LZW, ZIP, or JPEG or maybe you always keep the default option, which is “None”, because you are afraid that the compression you choose may degrade the quality of your images.įirst, let’s clarify that both LZW and ZIP are lossless types of compression, which means they reduce the file size of an image but do not reduce the image quality. When saving images in TIFF format many software offers to choose image compression for your files.
