inputprobe DPI Test VS imagecli

• Measures, does not guess
  A browser cannot ask a mouse for its DPI, so this measures it: you drag the mouse along a reference object of known size and it counts the movement the mouse actually reports over that distance.
• Standard physical references
  Measure against a bank card, whose long edge is 85.60 mm by ISO/IEC 7810, or A4 or US Letter paper at 297 mm and 279.4 mm. The reference is an international standard, so no ruler is involved.
• Three passes, median and spread
  You get the median of three passes plus the spread between them. Passes landing within a percent or two mean the measurement was repeatable; a wide spread means something interfered, and the tool says so.
• Refuses rather than guesses
  When the three passes disagree, no DPI figure is reported. An honest refusal is more useful than a confident wrong number, and the page explains what to change before trying again.
• Free, local, nothing uploaded
  Free and runs entirely in your browser. No account, no signup, no install, and nothing about the measurement leaves your machine.

• Simple CLI interface
  image-cli offers a straightforward command-line interface that lets users perform common image operations like resizing, converting formats, and compressing without writing code, making it accessible for quick tasks and scripting.
• Built on Sharp
  Under the hood it leverages the Sharp library, which is known for high performance and low memory usage when processing images, so users benefit from fast conversions and resizing even for large batches.
• Multiple format support
  The tool supports converting between popular image formats such as JPEG, PNG, WebP, and AVIF, giving developers flexibility to optimize images for web or other platforms without needing separate tools.
• Batch processing
  image-cli can process multiple files or entire directories in one command, which is useful for automating image optimization pipelines in build scripts or CI/CD workflows.
• Lightweight and easy to install
  As an npm package, it can be installed quickly via npm or yarn and used directly with npx, requiring minimal setup compared to more complex image processing suites.

Possible disadvantages

• Limited advanced features
  Compared to full-featured image editing suites, image-cli offers a relatively narrow set of operations (resize, convert, compress) and lacks more advanced manipulations like layers, filters, or complex transformations.
• Dependency on Node.js ecosystem
  Since it's an npm-based CLI, users need Node.js and npm installed, which adds an extra dependency for those who just want a standalone binary without a JavaScript runtime.
• Documentation gaps
  Being a smaller, less mainstream project, the documentation may be sparse or lack detailed examples for edge cases, making it harder for new users to discover all available options or troubleshoot issues.
• Maintenance and community support
  As a side project by an individual maintainer (egoist), the tool may receive infrequent updates or slower bug fixes compared to more actively maintained, enterprise-backed image processing tools.
• Limited error handling and feedback
  Some users report that error messages when processing fails (e.g., unsupported formats or corrupted files) can be unclear, making debugging batch operations more time-consuming.
