Image Dimensions & Specs Checker
Check resolution, pixel dimensions, file size, aspect ratio, and megapixels of any image file.
How to Use Image Details Checker
- Drop any image or photo into the inspector box.
- Immediately view resolution (width × height), total megapixels, and aspect ratio.
- Review print dimensions at 300 DPI (inches and cm) and decoded RAM memory usage.
- Click 'Copy Specifications' to copy summary metrics to your clipboard.
Technical Specifications & How It Works
Digital images contain spatial dimensions (pixels), density attributes (DPI), and binary storage weights.
Understanding print dimensions at 300 DPI prevents blurry or pixelated physical printouts.
100% Client-Side Privacy: Your images never leave your computer or phone. Processing runs completely in local browser memory via WebAssembly and Canvas APIs. No file data, filenames, or metadata are ever transmitted.
Frequently Asked Questions
What DPI is needed for high-quality printing?
Standard commercial printing requires 300 DPI (dots per inch) for crisp, professional clarity.
How are megapixels calculated?
Megapixels equal (Width in pixels × Height in pixels) divided by 1,000,000.
What is uncompressed RAM size?
When an image is decoded for display or editing, each pixel typically occupies 4 bytes (Red, Green, Blue, Alpha) in volatile RAM memory.
