Image Dimension Checker
Upload an image to see its exact pixel dimensions, file size, format, aspect ratio, and DPI when available. Everything happens locally in your browser.
What does this tool do?
This tool reads and displays the technical details of an image file: its exact width and height in pixels, file size, format, aspect ratio, and — when the file includes it — DPI (dots per inch) resolution. It's a quick way to confirm exactly what you're working with before uploading or printing an image.
When should you use this tool?
- A form or platform requires specific pixel dimensions and you need to check if your image qualifies
- You're preparing an image for print and need to confirm its DPI
- You want to quickly compare the aspect ratio of an image against a target ratio
- You need the exact file size before attaching it somewhere with size limits
Why use Orisod for this?
All the details are read directly from the file locally in your browser — nothing is uploaded to a server. If the file includes DPI metadata (common in JPEG and PNG files prepared for print), it will be shown; otherwise the tool tells you it wasn't found rather than guessing.
Frequently asked questions
Why does DPI show as "not found" for some images?
Not every image file stores a DPI value — many web images and screenshots simply don't include it. When present, it's usually meant for print reference rather than screen display.
What's the difference between pixel dimensions and DPI?
Pixel dimensions (like 1920×1080) are the actual number of pixels in the image. DPI describes how densely those pixels are meant to be printed per inch — the same pixel image can be printed larger or smaller depending on DPI.
Is my image uploaded anywhere?
No, the entire process happens locally in your browser using JavaScript.
What formats are supported?
JPG, PNG, WEBP, GIF, and other common formats your browser can read. DPI detection currently works for JPEG and PNG files.
