This invisible cruft can includes location information in EXIF data from cameras. This app can also remove image metadata attached to an image. It also lets the user specify a suffix to apply to the filenames of converted images (this defaults to -min). Now, if you want it do that you can enable it from the preferences, but it’s not default. I also like the fact that Curtail does NOT overwrite the original image file by default.

You can adjust lossy and lossless compression levels I love that that it’s super easy to use: open the app, drag and drop a bunch of PNGs and JPGs on its window, and poof: smaller images instantly pop out the other end. If I need to compress PNG, JPG, and WEBP images quickly and in bulk on Ubuntu (or Fedora, which I do use regularly) I use Curtail.

Written in Python, Curtail makes use of the open source OptiPNG, pngquant, and Jpegoptim libraries to “perform” the actual compression, and presents an attractive, easy-to-use frontend written in GTK. Curtail is a Capable Image CompressorĬurtail is an open-source image compression tool for Linux desktops.

Thing is, I prefer desktop apps where possible. Not only is there a broad range of image compression apps for Linux, from powerful CLI type through to noob-proof GUI ones, there’s also a veritable surfeit of online compressors (including superbly useful Squoosh which works offline). Thankfully for those of us being mindful of bandwidth we are spoilt for choice. Thus having access to a good image compressor tool is a must. Running a blog like this one means I have to keep an eye on the size of image screenshots I use in posts - the smaller the image I upload, the faster the page loads for readers.
