sudo apt install flatpak -y

sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Section 4: How to Begin Utilizing Curtail on Ubuntu Linux and Reduce Image Size

Step 1: Choosing the Right Compression Level

  • Low compression: Choose this level when you need to maintain high image quality while slightly reducing the file size. This option is ideal for professional photography or high-resolution images.
  • Medium compression: This level offers a good compromise between image quality and file size reduction. It’s suitable for everyday use, such as sharing images on social media or websites.
  • High compression: When you need to drastically reduce the file size and are willing to accept a discernible loss in image quality, choose heavy compression. This level is ideal for optimizing images for low-bandwidth connections or limited storage space.

Step 2: Batch Compressing Images

You can save time and effort by compressing numerous pictures at once with Curtail. To compress photos in bulk, take these actions:

Launch Curtail.

  1. To add numerous photos to the Curtail box, either click the Add button or drag and drop them.
  2. Choose your desired compression level using the slider.
  3. Press the Compress button to start the batch compression process.

Step 3: Customize Curtail Settings

Some customization options include:

  • Keep original file’s metadata: Enable or disable this setting to choose whether to retain the original image’s metadata during compression.
  • Overwrite original files: Select this option if you want Curtail to overwrite the original images with the compressed versions. Curtail will generate new files for the compressed pictures if it is disabled.
  • Change output folder: Curtail stores compressed photos by default in the same folder as the source files. You can change this by specifying a different output folder.

Step 4: Monitor Compression Progress

Throughout the compression process, Curtail shows the status of each image and a progress meter. This feature allows you to monitor the progress and ensure that your images are compressed as expected.
