Forensic Unit Conversions

This utility supports **Inches, CM, MM, and Twips**. For designers, we also provide **REM** calculations based on a 16px root font. Export your calculations using the **CSV** or **TXT** buttons in the history panel to keep permanent records of your assets.

Calculating Physical PPI

To find your monitor's pixel density, input its resolution and diagonal screen size. A PPI over 200 is generally considered "Retina" quality, where pixels are indistinguishable to the eye.

Viewing Distance Logic

Large format prints viewed from meters away require lower DPI. Use the distance slider to find the optimal DPI based on visual acuity, helping you save file size without losing perceived sharpness.

Batch Processing

Our tool uses `createImageBitmap` for background decoding. You can scan entire folders of images locally to check **Aspect Ratios** and **Print Suitability (PPI)** in seconds.

Frequently Asked Questions

It is a local-only design toolkit for unit conversion, image analysis, and metadata extraction. No data is ever sent to a server.

A Twip is $1/1440$ of an inch. It's a device-independent unit used in legacy Windows software and modern rich-text formatting.

As you stand further away, your eye resolves less detail. Therefore, billboards need lower DPI than handheld photos to look "perfect."

You can export your session history as a **CSV** (for spreadsheets) or a **TXT** (as a readable report). Both formats include all forensic units.

PPI is Pixels Per Inch (screens), DPI is Dots Per Inch (ink on paper). In design math, they are used as the same variable.

It performs a high-density grid scan of the image to identify the most unique and dominant colors, ensuring a representative palette for your brand.

Yes, it runs in the background. You can interrupt the process at any time by pressing the **ESC** key.

Divide CM by 2.54 for inches, then multiply by your target DPI. For example, 10cm at 300 DPI is ~1,181 pixels.

The tool focus is on visual data; it saves the pure pixel data of your selection into the new file format chosen.

If the original pixel count is low and you increase the DPI, the physical size shrinks. Upscaling a small image to a large physical size will always cause blur.

It refers to the use of high-precision math (floating point) rather than simple rounding, ensuring measurements are pixel-perfect for professional production.
