What It Is

DXOMARK is a professional quality testing laboratory headquartered in Boulogne-Billancourt, France, with its image quality testing origins dating back to 2003. Using a methodology of "scientific measurement + perceptual evaluation", it provides ratings and rankings for consumer and professional products including smartphone cameras, front-facing cameras, displays, audio, batteries, camera sensors, interchangeable lenses, wireless speakers, and laptops. Its ratings are widely cited across the industry, and are often used as "promotional data selling points" in manufacturers' product launch events.

Core Features

• Multi-dimensional testing reports: For every smartphone camera test, DXOMARK shoots over 1,600 test images and more than 2 hours of video, covering all lighting conditions in both laboratory and real-world scenarios.
• Professional measurement data: Camera sensor testing is based on RAW format, measuring metrics including color sensitivity, noise, dynamic range, and ISO sensitivity; lens testing covers indicators such as sharpness.
• Rankings and custom sorting: It offers ranked lists for categories including Smartphones, Camera Sensors, Lenses, Speakers, Laptops, as well as a Custom Ranking tool.
• Transparent methodology: The website publicly discloses test protocols and process descriptions for all categories, including detailed testing procedures for audio, displays, and cameras.
• B2B services and Smart Choice badge: It provides product quality assessment solutions and certification badges for brand manufacturers.

It is worth noting that DXOMARK has recently begun developing testing methodologies for Smartglasses, an emerging category of imaging devices.

Pricing

All content on the website is completely free for personal "private use" and "fair use" as defined by law, but its copyright terms are quite strict: copying, rewriting, and commercial redistribution are prohibited, and media citations must credit the source and include a link; enterprise use and B2B testing services require separate authorization and custom pricing.

Pros & Cons

Pros: Scientific methodology, wide product category coverage, high credibility for ratings, available in Chinese, detailed and free content.

Cons: Strict copyright restrictions hinder secondary sharing; its rating system has long faced controversy over "whether it is influenced by manufacturer payments or partnerships"; it only provides reference ratings and does not sell products directly.

Who It's For

It is suitable for general consumers looking up authoritative reviews before buying a phone or camera, photography enthusiasts, digital media practitioners, as well as hardware manufacturers seeking third-party quality endorsement.

Access from China

The website can be accessed directly without any workarounds, and it offers an official Chinese language version, providing a good user experience for users in China.
