Check Image Dimensions

Read decoded image width, height, pixel count and aspect ratio without uploading the file.

Image DPI checker: Read saved PNG/JPEG density records and calculate physical size from the image pixels and an explicit DPI.

Your selected images stay in this browser. No AI model call or server upload.

Selected files: 0 · PNG, JPEG and WebP. Up to 8 MB per file and 12 million decoded pixels. Batch totals cannot exceed 40 MB. Exports are still images; animation is not retained.

Exported images do not carry the original saved prompts, EXIF or Content Credentials. Keep the original file when you need its creation records.

Dimensions reflect the image as decoded and oriented by your browser. They are separate from saved generation dimensions or print DPI. The report includes the original file size in bytes.

How to use this tool

  1. Choose the image whose size you need to check.
  2. Run the tool to read decoded width, height, total pixel count and reduced aspect ratio.
  3. Read the original file size separately from the dimensions, then copy the result data or download JSON.

Frequently asked questions

How do I check an image's width and height?

Choose a supported file and run this tool. It reports the browser-decoded width and height in pixels, along with pixel count and aspect ratio. Your image stays in the browser.

Are image dimensions the same as DPI?

No. Pixel dimensions describe the raster size. DPI or PPI describes a print-density interpretation. This tool reports decoded pixels, not a print-DPI field or a generator's saved size setting.
