Build shell-safe ImageMagick v7 (`magick`) and v6 (`convert` / `mogrify`) commands with exact geometry modifiers (`^`, `>`, `!`), center-gravity cropping, sRGB color normalization, and batch folder pipelines.
Enter the inputs, then select Generate ImageMagick Command.

Unlike declarative CLI tools, ImageMagick evaluates options strictly left-to-right as a stack of image operations.
magick <input> -colorspace sRGB -resize "<W>x<H>^" -gravity center -extent <W>x<H> -strip -quality <Q> <output>
Always place input file first, pixel transformations (-colorspace, -resize, -extent, -unsharp) in the middle, and encoding flags (-strip, -quality) immediately before the output filename.
Compare how ImageMagick geometry flags transform a `2400×1200` (`2:1`) source photo when targeting a `1200×800` (`3:2`) output box.
| Geometry Flag | CLI Syntax | Resulting Pixel Size (from 2400×1200) | Best Use Case |
|---|---|---|---|
| **Aspect-Fill + Crop (`^` + `-extent`)** | `-resize "1200x800^" -gravity center -extent 1200x800` | `1200×800 px` (scales to `1600×800`, crops `200 px` left/right) | Blog covers, Open Graph cards & product grids requiring exact `3:2` or `16:9` frames |
| **Fit Inside Box (Default)** | `-resize "1200x800"` | `1200×600 px` (preserves `2:1` aspect ratio inside box) | Lightbox galleries where full uncropped composition must remain visible |
| **Shrink Only (`>`)** | `-resize "1200x800>"` | `1200×600 px` (leaves a `800×400` image untouched) | User-uploaded avatars and CMS media pipelines avoiding blurry upscaling |
| **Force Exact (`!`)** | `-resize "1200x800!"` | `1200×800 px` (stretches height by `1.33x` non-proportionally) | Texture maps, LUTs, or synthetic masks where aspect ratio distortion is intentional |
Follow three steps to generate both a single-image command and a batch directory pipeline.
Enter your input file (such as hero-source.png) and target output (such as hero-cover.webp), and choose ImageMagick v7 ('magick'), v7 batch ('magick mogrify'), or legacy v6 ('convert').
Pick Aspect-Fill & Center Crop ('^' + '-extent') when you need exact card dimensions without distortion, or Shrink Only ('>') to cap maximum dimensions.
Set encoder quality (82 is optimal for WebP covers) and enable '-colorspace sRGB -strip' to remove camera EXIF bloat while preserving accurate web colors.
Verify these three production commands for responsive web assets and batch folder conversions.
Running 'magick hero-source.png -colorspace sRGB -resize "1200x800^" -gravity center -extent 1200x800 -strip -quality 82 hero-cover.webp' scales any source image to fill 1200×800 px, center-crops excess edges, strips EXIF, and encodes at WebP Q82.
Switching to 'magick mogrify' generates 'magick mogrify -path out -format webp -colorspace sRGB -resize "1200x800^" -gravity center -extent 1200x800 -strip -quality 82 *.png', converting an entire folder in one pass.
Selecting Shrink Only ('>') with 1920×1080 outputs '-resize "1920x1080>"', ensuring 4K photos are downscaled while 800×600 screenshots remain at native resolution.
The tool outputs your primary one-liner plus cross-platform batch equivalents.
The primary result displays the exact one-line command ready to paste into your terminal, along with target aspect ratio and geometry behavior summary.
The detail breakdown includes a POSIX 'for' loop and a 'magick mogrify' command so you can run the exact same transformation across hundreds of files.
Check these environment details when running ImageMagick on CI runners or production servers.
WebP and AVIF output require 'libwebp' and 'libheif' delegates compiled into ImageMagick. Run 'magick -list format | grep -E "WEBP|AVIF"' to verify read/write ('rw+') support.
When processing untrusted user uploads on servers, configure '/etc/ImageMagick-7/policy.xml' to cap maximum memory, disk cache, and pixel dimensions (e.g. width/height <= 16KP) and disable Ghostscript (PS/PDF/EPS) coders.

Open toolAnswers about using ImageMagick Command Generator (magick v7 Resize, Crop, WebP & Batch CLI) and understanding its results.
ImageMagick 7 replaced the standalone 'convert' binary with the unified 'magick' command (which also prevents Windows path conflicts with the built-in NTFS convert.exe utility). For batch in-place or directory output in v7, run 'magick mogrify' instead of standalone 'mogrify'.
Combine the caret '^' geometry flag with gravity and extent: '-resize 1200x800^ -gravity center -extent 1200x800'. First, '1200x800^' scales the image so both dimensions are at least 1200x800; next, '-gravity center -extent 1200x800' crops excess pixels evenly from the center.
In POSIX shells (bash/zsh), '>' is the output redirection operator, so unquoted '-resize 1200x800>' will overwrite a file named '1200x800'! In Windows cmd.exe, '^' is the escape character. Wrapping the geometry argument in double quotes ("1200x800^" or "1200x800>") is safe across Bash, Zsh, and PowerShell.
Photos exported from cameras or macOS Display P3 / AdobeRGB workflows embed ICC profiles that inflate small thumbnails by 3 KB to 60 KB, or render with desaturated colors if '-strip' removes the ICC profile without first converting pixel values to sRGB. Placing '-colorspace sRGB' before '-strip' bakes standard web colors into the image and deletes private GPS/EXIF metadata.
