When a folder of images needs the same resize or format change, ImageMagick can process the files through command-line commands and scripts. It also handles individual edits, image composition, and metadata tasks from the same toolset.
Convert and resize image files
ImageMagick supports over 200 image formats. A command can convert an image while resizing it, such as magick input.jpg -resize 1200x output.png; the example limits the output width while retaining the image proportions. Other editing operations include cropping, rotation, flipping, borders, blur effects, and adjustments to brightness, contrast, or saturation.
Commands can also add text or watermarks, combine images, and apply the same treatment across a batch. For a folder of assets, that means setting a repeatable conversion or editing step instead of handling every file separately.
Automate repeat edits with scripts
ImageMagick’s command-line workflow fits into shell scripts and other automated processes. A script can take images from a folder, resize them to a chosen dimension, and save them in another format. This is handy for repeat jobs such as preparing a consistent set of images for a site or application.
Because the operations are expressed as commands, the same sequence can be rerun when new files arrive or included in a larger image-processing workflow.
Build compositions and animated GIFs
The montage and image-composition tools can arrange multiple files into a combined image, including horizontal or vertical layouts and collages. ImageMagick can also create an animated GIF from a sequence of image files.
It can generate a new image from specified properties such as its dimensions, background color, and content, in addition to working with existing pictures.
Inspect and manage image metadata
ImageMagick can display technical image information and work with EXIF, IPTC, and XMP metadata. Metadata operations include viewing, changing, or removing embedded data, such as information that identifies how or when an image was captured.
Pros
- Converts among formats including JPEG, PNG, GIF, TIFF, BMP, and SVG
- Automates repeated edits with scripts and batch commands
- Includes tools for composing images and creating animated GIFs
- Reads and edits EXIF, IPTC, and XMP metadata
Cons
- Image editing is performed through command-line tools, without a graphical editor
