Image Info Viewer

The Image Info Viewer is a free online tool that extracts detailed metadata and technical specifications from your picture files. It is highly useful for photographers, developers, and digital archivists who need to check resolution, file size, and aspect ratio details. You can use it anywhere to verify image properties before uploading them to print or web platforms.

How the Image Info Viewer works

  1. 1

    Upload your image file into the viewer workspace. The tool reads the file locally and never uploads it anywhere.

  2. 2

    The viewer reports the core file properties: file name, format type, size in KB, pixel dimensions, the mathematically reduced aspect ratio, megapixels, and the last-modified date.

  3. 3

    All properties appear as a clean stat grid. Use these numbers to judge whether an image fits your layout, budget, or quality requirements before publishing.

Real-world examples

Photography Archiving

Input: A raw photo taken with a DSLR camera.

Results: Pixel dimensions, reduced aspect ratio, and megapixel count at a glance.

Use case: Photographers catalog shots by resolution and size without opening an editor.

Web Optimization

Input: A large banner image for a website.

Results: File size, dimensions, and aspect ratio information.

Use case: Web developers use this to identify images that need compression to improve page load times.

Legal Verification

Input: A photo submitted as evidence.

Results: The file's last-modified timestamp plus exact dimensions.

Use case: Investigators document basic file properties before deeper forensic analysis.

Print Preparation

Input: An image intended for a magazine cover.

Results: Megapixels and dimensions to judge whether resolution is sufficient.

Use case: Print designers use this to check images against minimum quality requirements.

Privacy Checking

Input: A photo about to be shared on social media.

Results: File name, type, size, and modified date, read entirely offline.

Use case: Privacy-conscious users inspect basic properties before posting photos online.
