Professional Image Size and Resolution Auditor

Analyze Dimensions in Pixels, MM, and Inches with Smart DPI Conversion

Is your image web-ready or print-perfect? Understanding the relationship between pixels and physical size is essential for modern creators. Our Advanced Image Size Checker is a high-precision tool that provides an instant diagnostic of your media assets, calculating dimensions across every major unit of measurement in real-time.

At ImageXYZ, we believe in security-first performance. By using Client-Side Metadata Extraction, your images are audited entirely within your browser. Your private data never touches a server, making this the most secure way to audit professional photography and sensitive documents.

Why Multi-Unit Dimension Analysis Matters

  • Web Performance (Pixels): Identify heavy files that trigger Largest Contentful Paint (LCP) warnings. Our tool categorizes your “SEO Health” so you know exactly when to compress.
  • Print Precision (MM/CM): Planning a brochure or poster? Switch to 300 DPI to see exactly how many millimeters or centimeters your digital file will occupy on paper.
  • Global Compatibility (Inches): Perfect for international design standards, our tool provides high-fidelity inch calculations based on your custom DPI (Dots Per Inch) selection.
  • iPhone and Modern Formats: Natively check the dimensions of HEIC, WebP, and SVG files without needing to convert them first.

How to Audit Your Images with DPI Scaling

  1. Select Your Resolution: Choose from 72 DPI (Standard Web) to 300 DPI (High-Quality Print) from our DPI Selector.
  2. Drop and Process: Drag your file into the zone. Our engine instantly calculates the file weight and physical dimensions.
  3. Review the Report: Get a row-by-row breakdown of size, format, and unit-specific dimensions (px, mm, cm, in).

Expert Insights: The “Golden Rule” of Resolution

For the best user experience in 2026, always check your DPI before printing. A 1200px image might look huge on your monitor, but at a professional 300 DPI print setting, it only measures about 4 inches. Using this auditor ensures your final product is never blurry or pixelated.

Privacy Guarantee: Our “Zero-Upload” architecture means your pixels stay on your hardware. We provide the expertise; you keep the data.

Frequently Asked Questions (FAQ)

What is the difference between PPI and DPI?

While often used interchangeably, PPI (Pixels Per Inch) refers to digital display, while DPI (Dots Per Inch) refers to printed output. Our tool calculates both to ensure your dimensions are accurate for any medium.

How does changing the DPI affect my image size?

Changing the DPI in our tool doesn’t change the pixels in your image; it changes the calculated physical size. Higher DPI means smaller physical dimensions but higher print quality.

Can I check the size of multiple images at once?

Currently, this auditor is optimized for a Deep-Dive Single Image Audit. For multiple files, we recommend using our Bulk Image Resizer.
