Resizing all images in a folder

Well, the most common application (tool) that I use in Linux for quick resizing an image is imagemagick an cmd based tool
The best 2 commands that I use most are:

Resizing just an image we use (convert):
This command actually takes image.jpg and resizes it on 500×500 pixels but it depends on the real size image so if it’s 600×500
the command wont deform its shape and make it like a square, but it’ll make it exc 500×400

# sudo convert image.jpg -resize 500x500 *.jpg

Resizing all images in a folder we use (mogrify):
When using mogrify its important to tell the path of images.

# sudo mogrify -path /home/user/yourimagesfolder/ -resize 500x500 /home/user/yourimagesfolder/*.jpg

What is GIMP ?

GIMP ( GNU Image Manipulation Program) is a free software raster graphics editor. It is primarily employed as an image retouching and editing tool. and is freely available in versions tailored for most popular operating systems, including but not limited to Microsoft Corporation’s Windows platform, Apple’s Mac OS X, and GNU/Linux.

What is Inkscape?

Official Inkscape Logo

Inkscape is an Open Source vector graphics editor, with capabilities similar to Illustrator, Freehand, CorelDraw, or Xara X using the W3C standard Scalable Vector Graphics (SVG) file format. Supported SVG features include shapes, paths, text, markers, clones, alpha blending, transforms, gradients, patterns, and grouping. Inkscape also supports Creative Commons meta-data, node editing, layers, complex path operations, bitmap tracing, text-on-path, flowed text, direct XML editing, and more. It imports formats such as JPEG, PNG, TIFF, and others and exports PNG as well as multiple vector-based formats. It can also export JPG with a little trick.

The main goal of Inkscape is to create a powerful and convenient drawing tool fully compliant with XML, SVG, and CSS standards. The guys over at Inkscape aim to maintain a thriving user and developer community by using open, community-oriented development.

The term Inkscape is made up of the two English words ‘ink‘ and ‘scape‘. Ink is a common substance for drawings, and is used when the sketched work is ready to be permanently committed to paper, and thus evokes the idea that Inkscape is ready for production work. A scape is a view of a large number of objects, such as a landscape or ocean-scape, and thus alludes to the object-oriented nature of vector imagery.

What is vector graphics?

In contrast to raster (bitmap) graphics editors such as Photoshop or Gimp, Inkscape stores its graphics in a vector format. Vector graphics is a resolution-independent description of the actual shapes and objects that you see in the image. A rasterization engine uses this information to determine how to plot each line and curve at any resolution or zoom level.Contrast that to bitmap (raster) graphics which is always bound to a specific resolution and stores an image as a grid of pixels.
