Nautilus Image Converter is a popular extension among Ubuntu users to batch resize and rotate images. While it’s handy, it’s tied to the Nautilus file manager and is not available for users who use other flavours of Ubuntu e.g. Xubuntu or Lubuntu. imgd (read imaged) is a multiprocessing command-line alternative written in Python3. It uses the PIL (Pillow) library and has many more additional features. Continue reading imgd: multiprocessing image resizer and rotator
We explored some utilities to optimize png, jpeg and gif images earlier. Though they yield very good results, a common problem is the need to specify the optimization level manually. Most users would use a 80%-85% level in fear of ruining the image quality. imgmin is a promising project that attempts solves this problem by calculating the optimal level mathematically and automating the process without manual intervention.

There are many situations where you would want to optimize or compress images. For example, to send family pics to your parents or to upload in your website. Though new image formats are emerging, JPEG, PNG and GIF are still the most used formats. Continue reading Optimize images from cmdline

It strikes a balance between quality and image size so that the difference between the optimized and original images is not visually detectable. Continue reading TinyJPG: optimize JPG, PNG images
Compressing images before uploading them online saves both bandwidth and online storage. Kaken claims to achieve good lossless and lossy compression without compromising the quality of images visibly. You can upload your files from your desktop, use Kraken to compress them and finally download them individually or all in a zip archive. When I tried some of my images including a 3.6KB image I wasn’t disappointed. And I must mention that Kraken is fast.
If you are into blogging like me or handle a website, you know that using small size images of good quality is very important to keep the pages responsive. If you are using GPicView on Ubuntu, you will find options to save images in different formats and quality when you open one. Continue reading Trimage: compress images on Ubuntu
