the Web scraping is not illegal in and of itself. Extracting public data on internet is a legal practice, provided that the following are observed: Terms of Use of the site, the RGPD and the game's copyright.
Here are the rules you need to know before you get started.
Is web scraping legal? What the law says
the web scraping is to extract data automatically from web pages. In practical terms, a tool crawls a website, reads the page code, and retrieves the information you're interested in. Generally speaking, this practice is legal as long as you stick to public data available online.
Legality depends primarily on three elements : the site's terms and conditions of use, the RGPD and the copyright. Web scraping becomes illegal when you access private information, such as personal data without a legal basis, or when you bypass a technical protection measure.
From a copyright perspective, the Intellectual Property Code regulates the collection, storage, and use of data. The producer of a database also features a sui generis right (Article L342-3 of the Intellectual Property Code), which prohibits the extraction of a substantial portion of a database, even if the information contained therein is publicly accessible.
As soon as you collect some personal data, you're entering the realm of the RGPD. It doesn't matter whether the data is public: you must have a legal basis (consent or legitimate interest), adhere to the principle of data minimization, and inform the individuals concerned. This is the point that many people overlook before getting started.
What factors make web scraping illegal?
Four factors come up most often: the Terms of Use, them copyright, the RGPD and disruption to the site's proper functioning. Here's what you need to check before extracting any data, whether you're doing price scraping or any other information.
Terms and Conditions of Use (TCU)
Websites have the right to set their own rules regarding access to their pages. You can find them in the Terms and Conditions of Use (T&C). These documents serve as legal contract between the website and its users.
If the document explicitly prohibits web scraping, your data collection could put you at legal risk. Under French law, violating the Terms of Service primarily constitutes contract law, it's not automatically a criminal offense, but it's a strong warning sign. So be sure to review the terms and conditions before starting your download.
Intellectual Property Rights
the copyright protects original works, including certain types of content and databases. If a website is protected by copyright, extracting its content without authorization may constitute a violation.
In France, the Intellectual Property Code Take it a step further with the sui generis right of the database maker (Article L.342-3). This right protects the investment made by the creator of a database, independently of traditional copyright. In practice, a substantial extraction The collection of data may be illegal even if that data is public. This is the point that is most often overlooked.
Personal data and GDPR
In Europe, scraping personal data (names, emails, profiles LinkedIn, accounts on the social networks…) is strictly regulated by the RGPD, and this even applies to data that is freely available on the internet. As soon as you collect information that identifies a person, you are engaging in a processing of personal data and you must have a legal basis : consent, legitimate interest, or legal obligation.
The GDPR also imposes positive obligations: to comply with the minimization, inform the people concerned, and set a shelf life limited. Without a clear legal basis, your data collection amounts to illegal web scraping. The CNIL may then impose penalties, including fines of up to 20 million euros Where 4 % of global annual revenue, whichever is higher.
Interference with the proper functioning of the website
Even on a site that allows web scraping, a intensive scraping may become illegal. This type of automated data extraction overloads the server and can prevent it from functioning properly, which is then considered a denial-of-service (DoS) attack.
In France, the’Section 323-2 of the Penal Code makes it a crime to interfere with an automated data processing system, with penalties of up to 5 years in prison and A fine of 150,000 euros. Professional tools such as Bright Data offer structured solutions to prevent this kind of abuse.
What are the best practices for legal web scraping?
Scraping legally is based on a few simple rules. They protect you from legal risks and comply with the Terms and Conditions of Use websites. If you want to understand Why Do Web Scraping?, so we might as well do it right from the start.
1. Respect the robots.txt file
Most websites include a file robots.txt, which specifies which pages can be crawled by bots, including scrapers. If this file prohibits access to a section, you do not scrape it. This is the foundation of a data collection respectful and compliant.
2. Limit the request rate
To avoid disrupting a website's server, you must Limit the frequency of your requests. Specialized tools make this possible, particularly those used in web scraping Python. They allow you to control the intervals between each request. A request rate that's too high can overload a server and result in legal penalties, so be sure to space out your calls.
3. Clearly identify yourself via the User-Agent
When scraping, it's best to use a User-Agent clear in your queries HTTP. This lets site administrators know that a script—not a human—is accessing the content. A User-Agent "identifiable" allows you to:
- Improve the transparency of your business
- Facilitate dialogue when problems arise
- Minimizing the Risk of Blockages
4. Focus on public data
To avoid legal risks, focus on the public data freely accessible on the internet—that is, information that anyone can view without having to register or log in first. Conversely, avoid extracting personal data or information password protected.
5. Use APIs if available
Many websites offer Web scraping API to retrieve their data in a legal and structured. This is the safest way to stay in compliance within the long-term legal framework. These official tools also offer greater stability than direct scraping. Start using them as soon as possible for your projects.
Is web scraping legal in France?
Yes, the Web scraping is legal in France, as long as you follow the legal framework in place. The collection of public data remains permitted, but it must comply with the RGPD, to Terms and Conditions of Use websites and to the copyright.

- Criminal penalties: The illegal collection of personal data is severely punished. The’Article 226-16 of the Penal Code provides for up to 5 years in prison and A fine of 300,000 euros for unfair or fraudulent collection practices.
- GDPR Penalties: For a company, a fine can amount to 4 % of global annual revenue Where 20 million euros, whichever is higher.
A concrete example: extracting profiles LinkedIn since the social networks for cold calling, without legal basis or failure to inform the individuals concerned, directly exposes one to a penalty from the CNIL. This is one of the most common instances of illegal scraping in practice.
