Converseen is a free and open source software for batch image conversion. With this tool, you can convert multiple images to another format, resize, change their aspect ratio, rotate or flip them all at once.
This is a handy tool for someone like me who has to deal with multiple screenshots of different size but has to resize them all before uploading to the website.
Batch conversion tools help a lot in such cases. This could be done in the Linux command line with the wonderful ImageMagick but a GUI tool is a lot easier to use here. Actually, Converseen uses ImageMagick underneath the Qt-based GUI.
Batch process images with Converseen
You can use Converseen to convert, resize, rotate and flip multiple images with a mouse click.
You have plenty of supporting options for the batch conversion. You can add additional images to your selection or remove some of them. You can choose to convert only a few of your selected images.
While resizing the images, you can choose to keep the aspect ratio. Keep in mind that out of width and height, the one you changed/typed last is the one controlling the aspect ratio. So, if you want to resize keeping the same aspect ratio but according to the width, don’t touch the height field.
You can also choose to save the converted images with different name in the same directory or some other location. You may also overwrite the existing images.
You cannot add folder but you can select and add multiple images at once.
You can convert the images to a number of formats like JPEG, JPG, TIFF, SVG and more.
There is also an option to give the transparent background a certain color while changing the format. You can also set the quality of the compression level.
Converseen says that it can also import PDF files and convert the entire PDF or part of it into images. However, it crashed in Ubuntu 21.04 each time I tried to convert a PDF file.
