Does ImageDetector.com Work Against Midjourney?

Midjourney images are everywhere now, and most of you might even be missing that fact as you scroll through Facebook, Reddit, Tiktok, or other social media sites.

Some of them are obvious — surreal lighting, hyper-detailed textures, faces that feel slightly “too clean.” Others are harder. They look like real photos at a glance, especially once they’ve been cropped, compressed, or reposted a few times.

That’s the point where AI image detection tools become useful. Not as final proof, but as a fast signal you can use before you escalate anything.

This article answers one narrow question: Does ImageDetector.com work against Midjourney images? The focus is practical — what to expect, what to watch for, and how to interpret results without over-trusting them.

What is ImageDetector.com?

ImageDetector.com is a web-based AI image detector designed for quick checks.

The workflow is simple: upload an image (or paste an image link), and it returns a detection result. There’s no sign-up, no dashboard to learn, and no heavy setup. It’s built to be used in the moment, not adopted as a full platform.

That low friction is the main reason people use it. Most teachers, editors, and creators don’t want a system. They want a fast answer.

In earlier testing, ImageDetector performed strongly overall on AI-generated images, averaging 97.64% across a five-item set. That doesn’t guarantee it will always catch everything, but it sets expectations for baseline performance.

What is Midjourney?

Midjourney is one of the most widely used AI image generators, known for high-quality, stylized outputs.

It’s particularly good at images that feel artistic: dramatic lighting, cinematic composition, textured details, and visual polish that can outperform many consumer-level generators.

Midjourney also has a distinct “signature” in some outputs — but that signature gets less obvious as prompts get more specific and images get edited after generation.

That’s why testing against Midjourney matters. If a detector can reliably flag Midjourney images, it’s usually a decent indicator that it handles mainstream AI generation well.

Why Midjourney is a fair stress test for detectors

At a glance, Midjourney is still “AI-generated.”

In practice, it’s a moving target.

Midjourney outputs often get:

• upscaled
• cropped
• filtered
• combined with real photos
• reposted through platforms that compress the file

Each step can remove or distort the signals detectors rely on. So a detector isn’t just competing against Midjourney. It’s competing against the messy ways people share images.

That said, Midjourney still tends to produce patterns that are statistically different from camera photos. Detectors don’t need to “see the prompt.” They just need enough of those patterns to remain intact.

So, What Do We Know?

Midjourney is a good benchmark because it produces polished images that can look real — especially once they’ve been cropped, compressed, or reposted.

Across 7 Midjourney tests, ImageDetector.com averaged 96.93%, which is a very strong result.

That said, all these tests still isn’t “every possible Midjourney style.” Edge cases will always exist — hyper-realistic generations, heavy post-editing, screenshots, and low-resolution reposts are usually where detectors get shakier.

Used the right way, ImageDetector is a solid screening tool. It gives you a high-confidence signal quickly. Just don’t treat it as proof on its own when the consequence is serious.
