Screenshot Scanner

Detect whether an image is a screenshot or a real photograph. Analyzes resolution, DPI, metadata patterns, and common device dimensions.

Screen Dimensions

Matches against 150+ known device screen resolutions.

Metadata Patterns

Screenshots lack camera EXIF — no focal length, ISO, or shutter speed.

All analysis runs locally in your browser. Nothing uploaded.

What it detects

The scanner checks image dimensions against 150+ known device screen resolutions (iPhones, iPads, Android phones, Mac Retina, desktop monitors), analyzes EXIF metadata for camera-specific fields that only real photos have, and examines file format and compression patterns typical of screen captures. Read our screenshot detection guide for manual techniques.

Why it matters

Content verification, journalism, and legal work often need to distinguish screenshots from photographs. Screenshots prove what was displayed on a screen at a given time, while photos capture real-world scenes. Knowing which one you have helps assess authenticity and evidentiary value. Pair with the Authenticity Checker for deeper analysis.

Frequently Asked Questions

How does the screenshot scanner detect screenshots?

It analyzes multiple signals: image dimensions against 150+ known screen resolutions, presence or absence of camera EXIF data (ISO, focal length, shutter speed), file format (PNG is common for screenshots), software metadata, and bytes-per-pixel ratio.

Can it detect cropped or resized screenshots?

Cropping or resizing removes the resolution match signal, making detection harder. However, missing camera EXIF and PNG format are still strong indicators even after editing.

Why do screenshots usually lack EXIF data?

Screenshots capture screen content, not light through a camera lens. There is no aperture, ISO, focal length, or GPS to record. Some devices add minimal metadata (timestamp, software name), but camera-specific fields are always absent.

Does PNG format always mean screenshot?

No. PNG is also used for graphics, logos, and lossless photo editing. But combined with no camera EXIF and a screen-matching resolution, PNG is a strong screenshot indicator.

Is my image uploaded to a server?

EXIF extraction uses the server briefly (auto-deleted in 1 hour). The screenshot detection logic itself runs entirely in your browser — dimensions, format, and signal analysis are all client-side.
