Converseen is a free and open source batch image converter and resizer. With it, you can quickly and easily convert your images to and from over 100 formats. It is based on Qt4, making it cross-platform, and it uses ImageMagick to handle the heavy lifting. Supported image formats include JPEG, PNG, EXR, SVG, Postscript, TIFF, PDF, and GIF.
Converseen is easy to install and use and will have you on your way to converting and/or resizing your small or large collection of images in just a few simple steps.
The Converseen website has binaries for the program available for Ubuntu, Fedora, and OpenSUSE, complete with installation instructions for each.
To install in Ubuntu, type the following in a terminal:
If you need to install it from source, follow these directions:
Setup and Conversion
Converseen’s global settings only have two options, one for language and the other for giving you the option to either automatically overwrite images with the same names or “ask first”.
The first thing you should do to begin converting is to select the images you want to manipulate. Click “Open Images”. In the file browser you can select more than one image in a directory by holding Ctrl and clicking each one, or select them all with Ctrl+A. Click “Open” to add them. If you later need to add more, click the “Add Images” button instead.
In the left column, you will see a preview of the selected image followed by settings to change resolution, dimensions, output directory, and batch name assignment for the new files. You can change dimensions using percentages or pixels. The “maintain aspect ratio” option allows you to set either a uniform height or width, while keeping the right aspect ratios for all images. If the output directory is the same as the current one, you will need to decide whether you want Converseen to overwrite the current files or create new ones. You can do this in the “Output Options” section.
If you want to rename your files, check the “Rename” option and then enter the new naming scheme you want to use. By default it is “#_copy”. That means, if the original is named Beach.jpg, the converted file will be named Beach_copy.jpg.
To convert the images you have added, check the files you want in the batch or click “Check All”. Then, select the image format you want from the dropdown menu. Be sure to click “Image settings” to configure any available features for that format. JPEG and PNG formats will have “compression level” settings that will affect image quality and size.
When you are satisfied with all of the settings and selected images, click “Convert”. A dialog box will appear showing you how many files have been converted and if there were any errors. When it finishes, click “Close”.
Converting a large number of images can become time consuming. With Converseen you can let it do the work while you do something else. It also cuts down the number of steps since you can convert and resize images all in one swing. With such an easy tool, you will be in image bliss.
