Convert Cr2 To Jpg Ubuntu

How to Convert CR2 to JPG or PNG in Ubuntu

If you have a lot of CR2 photos that you want to convert to either JPG or PNG format, you might be wondering how to do this in Ubuntu. CR2 is a raw image format used by Canon cameras, and it is not widely supported by image viewers or editors. Fortunately, there are some tools that you can use to convert CR2 files to more common formats in Ubuntu.

In this article, we will show you three ways to convert CR2 files to JPG or PNG using ImageMagick, ufraw and dcraw. These are command-line tools that can process multiple files in batch mode. You can also use graphical tools like darktable or rawtherapee, but we will focus on the command-line methods here.

Using ImageMagick

ImageMagick is a popular tool for image processing in Linux. It can convert images to and from a wide array of file formats, including CR2. To install ImageMagick, run the following command:

sudo apt install imagemagick

To convert a single CR2 file to JPG or PNG, use the convert command with the following syntax:

convert input.cr2 output.jpg

convert input.cr2 output.png

To convert multiple CR2 files at once, you can use a for loop:

for file in *.cr2; do convert "$file" "$ (basename $file .cr2).jpg"; done

for file in *.cr2; do convert "$file" "$ (basename $file .cr2).png"; done

You can also specify some options to adjust the quality or size of the output images. For example, to reduce the quality of JPG images to 80%, use the -quality option:

convert input.cr2 -quality 80 output.jpg

To resize the output images to a maximum width or height of 800 pixels, use the -resize option:

convert input.cr2 -resize 800x800 output.jpg

You can combine multiple options as well. For more information, see the ImageMagick documentation.

Using ufraw

ufraw is another tool that can convert raw images to other formats. It also has a graphical user interface called ufraw-gimp, which allows you to edit the raw images before converting them. To install ufraw and ufraw-gimp, run the following command:

sudo apt install ufraw ufraw-gimp

To convert a single CR2 file to JPG or PNG using ufraw, use the ufraw-batch command with the following syntax:

ufraw-batch --out-type jpg input.cr2

ufraw-batch --out-type png input.cr2

To convert multiple CR2 files at once, you can use a wildcard:

ufraw-batch --out-type jpg *.cr2

ufraw-batch --out-type png *.cr2

You can also specify some options to adjust the output images. For example, to set the white balance to auto, use the --wb option:

ufraw-batch --out-type jpg --wb auto input.cr2

To rotate the output images by 90 degrees clockwise, use the --rotate option:

ufraw-batch --out-type jpg --rotate 90 input.cr2

You can combine multiple options as well. For more information, see the ufraw-batch man page.

Using dcraw

dcraw is a simple and fast tool that can decode raw images and convert them to other formats. It supports many raw formats, including CR2. To install dcraw, run the following command:

sudo
