## Overview

ImgAuth is a web platform for reviewing images and documents for signs of tampering or AI generation. Users upload a document image such as an invoice, receipt, certificate or scan and receive a tampering result with a confidence signal, suspicious regions and a forged-region heatmap. A separate AI Image Detector scores whole images (portraits, scenery, products, artwork) for AI-generation signals, and a Real or AI Face entry point applies the same whole-image model to portraits and avatars.

## Key features

## Pricing

- **Free trial** ($0/one-time): 3 free credits, no credit card required
- **Basic** ($9.90/month): 50 credits per month, standard processing
- **Pro** ($24.90/month): 125 credits per month with priority processing

## Best for

- Triage of invoices, receipts, certificates and claim documents, and quick whole-image AI-generation checks as one input to a human review

## Who uses it

- Finance and accounts-payable teams
- HR and compliance teams
- Insurance claims reviewers
- Content moderation and trust-and-safety teams
- Individuals checking a suspicious file

## Strengths

- Focused on two clear tasks, document tampering and AI-generated image detection
- Heatmaps and suspicious-region outputs give reviewers something to check, instead of a bare score
- Free 3-credit trial with no card, and cancellation at any time with access until period end
- REST API for higher-volume and team workflows
- Candid limitations: outputs are described as review signals, with explicit scope boundaries

## Limitations

- No published accuracy figures or independent benchmarks
- Not a deepfake, face-swap, liveness or identity tool, and the site's wording on face-swap detection is inconsistent
- 10 MB file limit and no free ongoing tier after the 3 trial credits
- Mobile app is only announced, with an outdated launch estimate (Q2 2025) on the site
- Operating company is named only as ImgAuth Ltd, with no team or founding details published

## Not recommended for

- Deepfake or face-swap detection, liveness and identity matching, legal authenticity certification, or users who need a mobile app today

## FAQ

**What does ImgAuth check?**

It has two engines: document fraud detection for visual tampering in documents, and whole-image AI-generation review for general images and portraits. Results are signals for a human reviewer, not final verdicts.

**Can it detect deepfakes or face swaps?**

Not specifically. The FAQ says Real or AI Face does not specifically detect face swaps or deepfakes, liveness, identity or face-region tampering. It scores the whole image for AI-generation signals. The site's own wording is inconsistent on this point, so treat face-swap detection as unsupported.

**What files and sizes are supported?**

The document tool accepts JPG, JPEG and PNG up to 10 MB per file, and the AI Image Detector accepts supported image files up to 10 MB. The FAQ also mentions PDFs in the document workflow, while the document page points to a separate PDF forgery workflow.

**How much does it cost?**

New accounts get 3 free credits without a card. Subscriptions start at $9.90 per month for 50 credits (Basic) and $24.90 per month for 125 credits with priority processing (Pro), and one-time credit packs start at $9.99 for 50 credits.

**Does ImgAuth store my uploads?**

The terms say images are processed in memory and not permanently stored, although processing operations are logged to detect violations. The FAQ says uploads are not used to train public models.

**Is there a mobile app?**

Not yet. The download page lists iOS and Android versions as "Coming Soon" with no store links.
