Batch processing tif images? Converting .tif to .jpeg

Question

I'm trying to mass convert a handful of .tif files. I found phatch could look like a good candidiate but I'm running Ubuntu 11.04. Looks like they don't have a .deb for my version.

Anyone have any alternatives to phatch or any other recommendations as to quickly batch convert tif to jpeg files.

I'm looking for a non-Photoshop (ala Wine) solution.

Answer 1

Easy. Install imagemagick:

sudo apt install imagemagick

Its simplest usage is:

convert File.tif File.jpg

It is smart and goes by your file extension.

Now, for doing batch conversions, we shall use a loop.

cd into the directory where your tif files are.

then:

for f in *.tif; do  echo "Converting $f"; convert "$f"  "$(basename "$f" .tif).jpg"; done

Read also as:

for f in *.tif
do  
    echo "Converting $f" 
    convert "$f"  "$(basename "$f" .tif).jpg" 
done

That should do it!

Also, once you convert all of the files and verify the new jpg's integrity, just run rm *.tif in that directory to delete all your old .tif files. Be careful with asterisks though, don't add a space after the *, or you will delete all your files in the directory.

Tip: If you have a folder with subfolders that holds these images. You could use this for loop to find all .TIF files within that folder:

for f in $(find -name *.tif); do ...; done

Answer 2

I found this question while trying to do it myself; for future reference you can also do it like this:

convert *.tiff -set filename: "%t" %[filename:].jpg

or to put it in a subdirectory

mkdir jpg
convert *.tiff -set filename: "%t" jpg/%[filename:].jpg

Answer 3

Use mogrify, the tool intended for batch processing inside ImageMagick

mogrify -format jpg *.tif

In case you don't have ImageMagick:

sudo apt-get install imagemagick

Answer 4

I would like to add to @Matt's answer that if you would like the files to be saved in the subfolders you can do the following:

find . -iname *.tif | while read f; do echo "Converting ${f}"; convert "${f}" "${f%.*}.jpg"; done

This also handles the issue if your file-path/name has spaces in it.

Answer 5

Imagemagick should be able to convert them. It is a package of commandline programs, if you are OK with that.

Part of that is convert -

man convert:

convert - convert between image formats as well as resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much more.

Answer 6

If you prefer a GUI application, you can install Phatch through the normal repositories. Just open Ubuntu Software Center and search for it. I'm not on 11.04 anymore but I had it installed back then.

Answer 7

The answers above use *.tif for tif selection, but this will return an error if you have too many files in your current working directory. A simple workaround is to use a python script to convert each file in the cwd:

import glob, os

for c, i in enumerate(glob.glob('ecco_images/*')):
  print(' * converting', i)
  os.system('convert ' + i + ' ' + i.replace('.TIF','.jpg'))

The GIMP GUI Solution Using a Batch Process Plugin

Works in Ubuntu 18.04 using GIMP 2.8

Batch Processor Input dialog window

Batch Processor output dialog window

Installation Instructions

1. Download the current plugin file from DBP - David's Batch Processor homepage to your desktop. For Ubuntu 18.04 running Gimp 2. 8 the file that worked for me was dbpSrc-1-1-9.tgz.

2. Grab some GIMP development files:

   sudo apt-get install libgimp2.0-dev gcc cpp g++
   

3. Switch to the system source code directory:

   cd /usr/src/
   

4. Extract the plugin from your Desktop to its own source code directory. Replace [username] with your current username, and use the filename that you downloaded above in step 1:

   sudo tar -xvzf /home/[username]/Desktop/dbpSrc-1-1-9.tgz
   

5. Change to the plugin's source code directory:

   cd dbp-1.1.9
   

6. Compile the plugin:

   make
   

7. Install the plugin:

   sudo make install
   

8. Start GIMP and you will find the plugin under Menu > Filters > Batch Process
