Convert tiff to jpg linux

Convert folder with tiff to jpg by using mozjpg

I hear that mozjpeg is a nice jpeg compressor from Mozilla. How can I convert my folder with *.tiff to jpg from terminal using mozjpeg?

TIFF is a container. Chances are that your images are already in JPEG format, just wrapped inside TIFF.

You will have to build mozjpeg from source.

If you do have the packages to compile it, you can install it with the following command:

sudo apt-get install autoconf automake libtool nasm make pkg-config git 

git clone https://github.com/mozilla/mozjpeg.git 

cd mozjpeg autoreconf -fiv ./configure --prefix=/usr make 

You will have 2 options: to install with the command:

or to create a «deb» (that you then can use to install) with:

But it does not seem to support «tiff». So you need to extract the files 1st. See How to convert TIFF scan file to JPEG or PNG general file format in Ubuntu? for that.

This is a generic command to compress a jpg to 75%:

convert filename1.jpg pnm:- | cjpeg -quality 75 > filename2.jpg 

The jpegtran tool can be used to optimise an image:

jpegtran -outfile filename1.jpg -optimise -copy none filename2.jpg 

If you get any errors please edit your question and I’ll have a look.

I have checked all man-pages

/usr/share/man/man1/djpeg.1 /usr/share/man/man1/cjpeg.1 /usr/share/man/man1/jpegtran.1 /usr/share/man/man1/wrjpgcom.1 /usr/share/man/man1/rdjpgcom.1 

but I think I have to disappoint you. You can’t convert images from TIFF to JPEG with any of these programs.

After the installation with the steps described in Rinzwind answer I have installed the deb. The following files are installed:

/. /usr /usr/bin /usr/bin/cjpeg /usr/bin/djpeg /usr/bin/rdjpgcom /usr/bin/tjbench /usr/bin/wrjpgcom /usr/bin/jpegtran /usr/lib /usr/lib/libjpeg.so.62.2.0 /usr/lib/libturbojpeg.a /usr/lib/libturbojpeg.so.0.1.0 /usr/lib/libjpeg.a /usr/share /usr/share/man /usr/share/man/man1 /usr/share/man/man1/djpeg.1 /usr/share/man/man1/cjpeg.1 /usr/share/man/man1/jpegtran.1 /usr/share/man/man1/wrjpgcom.1 /usr/share/man/man1/rdjpgcom.1 /usr/share/doc /usr/share/doc/mozjpeg-3.1 /usr/share/doc/mozjpeg-3.1/wizard.txt /usr/share/doc/mozjpeg-3.1/usage.txt /usr/share/doc/mozjpeg-3.1/libjpeg.txt /usr/share/doc/mozjpeg-3.1/structure.txt /usr/share/doc/mozjpeg-3.1/README /usr/share/doc/mozjpeg-3.1/README-turbo.txt /usr/share/doc/mozjpeg-3.1/README-mozilla.txt /usr/share/doc/mozjpeg-3.1/example.c /usr/include /usr/include/jconfig.h /usr/include/turbojpeg.h /usr/include/jmorecfg.h /usr/include/jerror.h /usr/include/jpeglib.h /usr/lib/libjpeg.so /usr/lib/libturbojpeg.so /usr/lib/libjpeg.so.62 /usr/lib/libturbojpeg.so.0

Batch conversion of ‘.tif’ images to ‘.jpg’

I am using Manjaro Gnu/Linux. I have a directory named files, and under this directory, I have around 650 sub directories, with names such as: file1, file2, file3. Under each sub directory there are varying number of ‘.tif’ images (say, from 2 to 11). I want to write a command/script to automatically convert all ‘.tif’ images to ‘.jpeg’/’.jpg’ such that they remain in the same sub directory and have the same name as before. I know that there is the command:

convert source.tif ~/converted.jpg

After you cd into the main directory containing the subfolders.

IFS=$'\n' for i in $(find -type f -name "*tiff"); do echo $i convert $i $i.jpg done find -type f -name "*tiff" -exec rm <> \; 

IFS is the internal field separator

The one problem i am seeing is that i was not able to extract the basename of the file

Dont forget to first try in a small folder before you move to big

I would use a script similar to this one:

#!/bin/bash if [[ $# -gt 0 ]] then if [[ -d $1 ]] then cd $1 else echo "Given path leads to a file or the directory you are loking does not exist!" exit 1 fi fi for dir in */ do echo "Changing directory to $dir" cd $dir for image in * do if [[ -f "$image" ]] then filename="$" extension="$" if [[ "$extension" =~ ^ti[f]$ ]]; then echo "Converting $image to $.jpg" convert "$image" -compress JPEG -quality 50 "$.jpg" fi fi done cd - > /dev/null done 

1. Save this as batchJPEGConvert.sh
2. Use chmod 755 batchJPEGConvert.sh command to make this file executable
3. Use sudo cp batchJPEGConvert.sh /usr/local/bin command to make this script accessible across your system

You can run this script by typing either batchJPEGConvert.sh or batchJPEGConvert.sh path . The first option will run this script in the current working directory. The other option will try to change the working directory to a given path and run the script there. This script will only convert files ending with .tiff or .tif extensions. It will also apply JPEG compression.

Note that this script only works for directories which structure is similar to this one:

test ├── 1 │ ├── polski.jpg │ └── polski.tiff └── 2 ├── polski.jpg └── polski.tif

Re: How to Convert tiff to jpeg

I am looking for a stand alone application to do this. For example, I have tiff image on usb stick that came off of a mac. I just want a tool that will convert it to jpeg. I do not want to have to bring up gimp and poke around thru it just to do a simple chore.

I have «Sound Converter» that does a similar chore like if I want to send somebody a sound file that is .wav. I simply use sound converter to easily convert it to .mp3 so I can email it. I know I could do that with Audacity, but thats just too much trouble to convert 1 file.

Re: How to Convert tiff to jpeg

default image viewer offers save as. on right click

if you need batch jobs look at imagemagick package (convert command would be the one you want), though you would need to get your hands dirty in terminal. That’s not a bad thing though as these tools are so powerful, gui is pretty much impossible.

if your question is answered, mark the thread as [SOLVED]. Thx.

Re: How to Convert tiff to jpeg

Thanks. That wasn’t so painful. I just tried Imagemagic, but it was not quick and dirty. Did not want to cooperate. Permission denied.

Re: How to Convert tiff to jpeg

i suspect you don’t have permission to write on usb or something. Does it work when you copy it to your $HOME or by using some other path for destination file, eg

convert source.tif ~/converted.jpg
