Tools are interactive browser apps; there is no public API, no endpoints to call and no server-side processing. To use a tool, open its HTML page in a browser.

## What is an Image Dimension Analyzer?

Our online tool allows you to bulk determine the dimensions, size, and technical parameters of any number of images at once. All information is clearly displayed in a table and can be exported as a CSV or JSON file for further use in Excel, databases, or custom applications.

## How to Find Image Dimensions?

1. **Upload Images** - Drag and drop them or click to select (you can upload dozens or even hundreds at once)
2. **Automatic Analysis** - The tool instantly detects all parameters
3. **View Results** - Dimensions, size, format, megapixels, aspect ratio
4. **Export Data** - Download as CSV or JSON for further processing

## What Image Information Will You Get?

### 📐 Dimensions (Width × Height)

**Width and Height in Pixels:**

- Exact dimensions of each image
- Format: `1920 × 1080`, `4000 × 3000` etc.
- Important for: Web design, print, social media

**Usage Example:**

- Resolution check before uploading to web
- Size verification for print (300 DPI)
- Determining if images are HD, Full HD, 4K

### 📦 File Size

**Size in Various Units:**

- Format: Bytes, KB, MB, GB
- Automatic conversion to the best unit

## Frequently Asked Questions (FAQ)

### How many images can I analyze at once?

Theoretically unlimited, but for optimal performance, we recommend a maximum of 100-200 images at once. For larger volumes, process in batches.

### Does the tool work with RAW formats (CR2, NEF, ARW)?

No, browsers do not natively support RAW formats. Please use standard formats like JPEG, PNG, WebP, GIF, AVIF, or SVG.

### Can I export only selected images?

Currently, the export includes all uploaded images. For selective export, upload only the desired files.

### Are the dimensions in pixels or inches?

Dimensions are always in pixels. To convert to inches/cm, use the image's DPI (typically 72 DPI for web, 300 DPI for print).

### How to convert pixels to cm for print?

Formula: cm = pixels / DPI × 2.54 Example: 3000px at 300 DPI = 3000/300 × 2.54 = 25.4 cm

### Does the tool work offline?

Yes, after the page loads. It does not require an internet connection for image analysis.

### Can I analyze images from a URL?

No, currently we only support local files. Please download the images first, then upload them to the tool.

  });
```

**Excel:**

```
Data → From Text/CSV → Select file → Import
```

### Processing JSON

**Node.js:**

```
const fs = require('fs');
const data = JSON.parse(fs.readFileSync('image-dimensions.json'));

// Average size
const avgSize = data.reduce((sum, img) => sum + img.fileSize, 0) / data.length;

// Filtering large images
const large = data.filter(img => img.fileSize > 1000000);
```

**SQL (PostgreSQL):**

```
CREATE TABLE images (
  filename TEXT,
  width INT,
  height INT,
  filesize BIGINT,
  format TEXT,
  megapixels DECIMAL
);

COPY images FROM 'image-dimensions.csv' CSV HEADER;

-- Statistics
SELECT format, COUNT(*), AVG(megapixels)
FROM images
