overview

What imagemagick does

Connect an image and the node runs ImageMagick 7 with the input first and a workflow output path last. Set -resize to dimensions such as 800x600, 50%, or 68x22, then set output-format to png, jpg, webp, or gif.

-quality controls compression quality for formats that support it. -strip removes profiles, comments, and metadata. -auto-orient rotates pixels according to orientation metadata and then resets that orientation.

ImageMagick transforms pixels and image containers. It does not extract document text or preserve every format-specific metadata field. Use ExifTool to inspect metadata before stripping it.

use cases

Where imagemagick fits

Create a thumbnail

Set -resize to bounded dimensions and write a smaller image for reports or notifications.

Remove image metadata

Enable -strip to remove profiles, comments, and embedded metadata from the output copy.

Normalize orientation

Enable -auto-orient so photos display consistently after downstream processing.

guidance

Choosing imagemagick

Use ImageMagick when the workflow must alter image pixels, dimensions, orientation, compression, or format. Use ExifTool when metadata is the actual result.

exiftool

Reads image and document metadata without changing pixels.

tesseract

Extracts text from image pixels with OCR.

ffmpeg

Transforms video and audio, and can process image sequences.
