Is Viewing Illegal Pornography the Same as Possessing It? (2026 UK Law)
In Brief
Under UK law, viewing and possessing illegal pornography are treated as separate offences, but both can lead to serious criminal charges. Viewing or downloading an indecent image is typically prosecuted as “making” an image under section 1 of the Protection of Children Act 1978 – an offence that carries up to 10 years’ imprisonment. Possession, by contrast, requires proof that the material was within your custody or control and that you knew it existed on your device.
In practice, the distinction matters less than many people assume: if illegal images are found in your browser cache, download folder, or messaging apps, you could face charges for making, possessing, or both. This article explains the legal differences, the relevant legislation, current sentencing guidelines, and what to do if you are under investigation
What Is Illegal Pornography in the UK?
Not all pornography is illegal. Adults can legally view and possess mainstream adult pornography in the UK, provided both the content and the people involved are lawful. However, two main categories of material are strictly prohibited:
Indecent Images of Children
Any sexual or indecent image of a person under 18 is illegal. This includes photographs, videos, pseudo-photographs (computer-generated or AI-generated images that appear realistic), and even prohibited images such as cartoons or drawings of a sexual nature involving children. The relevant legislation includes:
- Section 1 of the Protection of Children Act 1978 – making, distributing, or possessing with intent to distribute
- Section 160 of the Criminal Justice Act 1988 – possession
- Section 62 of the Coroners and Justice Act 2009 – possession of prohibited images (non-photographic, e.g. CGI, manga, drawings)
The Crown Prosecution Service has confirmed that high-quality AI-generated indecent images can be prosecuted as pseudo-photographs under existing law.
Extreme Pornography
Under section 63 of the Criminal Justice and Immigration Act 2008, it is illegal to possess pornographic images that realistically depict:
- An act that threatens a person’s life
- An act that results (or is likely to result) in serious injury to a person’s anus, breasts, or genitals
- An act involving sexual interference with a human corpse (necrophilia)
- Sexual acts with a live or dead animal (bestiality)
- Non-consensual penetrative acts
The image must be “grossly offensive, disgusting, or otherwise of an obscene character” to fall within this offence.
Deepfake Intimate Images
Since 6 February 2026, it is a criminal offence to intentionally create a sexually explicit deepfake image of a real person without their consent. This offence was introduced by section 138 of the Data (Use and Access) Act 2025, which amended the Sexual Offences Act 2003.
“Making” vs “Possessing”: The Key Legal Distinction
This is the most important legal point for anyone concerned about viewing illegal content online. Under UK law, “making” and “possessing” are separate offences with different legal tests.
What Counts as “Making”?
The courts have interpreted “making” extremely broadly. Following the landmark case of R v Smith; R v Jayson [2003], the Court of Appeal confirmed that all of the following amount to “making” an indecent image:
- Downloading an image from a website onto a computer screen with the knowledge that it is, or is likely to be, an indecent image
- Opening an email attachment containing an image with the knowledge that it is, or is likely to be, an indecent image
- Accessing a website where images appear automatically (including pop-ups) with the knowledge that there may be pop-ups and that such pop-ups may include indecent images
- Receiving images via messaging apps such as WhatsApp, even if automatically downloaded, provided there was knowledge that indecent images may be received
- Saving images to a device, cloud storage, or external drive
In other words, viewing an indecent image online can amount to ‘making’ it where the legal test is satisfied, including the knowledge elements developed in the case law.
What Counts as “Possession”?
Possession is a narrower offence. Following R v Okoro [2018], the Court of Appeal established a two-part test. The prosecution must prove:
- Custody or control – the images are stored in a way that the suspect can access or retrieve them
- Knowledge – the suspect knew that they had the images on their device (though they need not have known the images were indecent)
This means that images buried in a browser cache that the user did not know about, or images that have been genuinely deleted and are no longer retrievable by the user, may not amount to possession. However, images saved to folders, messaging apps, or “vault” applications will almost certainly satisfy the test.
Why the Distinction Matters
The CPS guidance indicates that prosecutors should prefer charging “making” over possession wherever the evidence supports it, because the making offence covers a wider range of conduct. This means that even if a possession charge fails (for example, because images were in an inaccessible cache), a making charge may still succeed if the prosecution can show the images were deliberately viewed or downloaded.
| Making | Possession |
Legislation (indecent images) | s.1 Protection of Children Act 1978 | s.160 Criminal Justice Act 1988 |
Maximum sentence | 10 years | 5 years |
Requires proof of storage? | No – viewing alone is sufficient | Yes – custody or control |
Requires knowledge of content? | Yes, knowledge that the image is, or is likely to be, an indecent image | No, only knowledge that images exist on device, knowledge of what those images are is not required |
Covers browser cache? | Yes, if accessed with knowledge that the image is, or is likely to be, an indecent image | Only if user knew that the images existed and could access them |
Can You Go to Jail for Looking at a Website in the UK?
Yes. If the website contains illegal content, such as indecent images of children or extreme pornography. Viewing indecent images of children can amount to ‘making’ an image under section 1 of the Protection of Children Act 1978. Extreme pornography is generally prosecuted as a possession offence under section 63 of the Criminal Justice and Immigration Act 2008.
The severity of the consequences depends on the nature of the material:
- Indecent images of children (Category A): Starting point of 1 year’s custody for making; up to 10 years’ imprisonment in the most serious cases
- Indecent images of children (Category C): May result in a community order for a first offence
- Extreme pornography (life-threatening acts, acts involving serious injury, or non-consensual penetrative acts): Up to 3 years’ imprisonment
- Extreme pornography (necrophilia or bestiality): Up to 2 years’ imprisonment
Even where a custodial sentence is imposed, the court must now consider the statutory presumption of suspension for sentences of 12 months or less, introduced in March 2026. This means short custodial sentences may be suspended in appropriate cases, though this is not guaranteed – particularly for sexual offences.
Indecent Images of Children – Sentencing Ranges
Category | Making & Possession (s.1 PCA 1978 & s. 160 CJA 1988) |
Category A (penetrative/sadistic/beastiality) | Starting point: 1 year’s custody; Range: 26 weeks – 3 years |
Category B (non-penetrative sexual activity) | Starting point: 26 weeks’ custody; Range: high-level community order – 1 year 6 months |
Category C (other indecent images) | Starting point: high-level community order; Range: medium-level community order – 26 weeks |
Statutory maximums: 10 years for making/distributing; 5 years for simple possession.
Aggravating and Mitigating Factors
Courts will increase the sentence where aggravating factors are present, such as:
- Large volume of images or a collection built over time
- Previous convictions, especially where relevant, e.g. for sexual offences
- Commercial gain or involvement in organised networks
- Child depicted known to offender or a large number of different victims
Mitigating factors that may reduce the sentence include:
- No previous convictions
- Evidence of genuine remorse and steps taken to address behaviour
- Co-operation with the police investigation
- Good character
Recent Legal Changes Affecting These Offences
Several significant legal developments have occurred since this article was first published in 2022:
- Online Safety Act 2023: From 25 July 2025, all pornographic websites accessible in the UK must implement robust age verification. Platforms that fail to comply face fines of up to £18 million or 10% of global revenue. The obligation falls on the website operator, not the viewer.
- AI-generated images: The CPS updated its guidance in May 2024 to confirm that high-quality AI-generated indecent images can be prosecuted as pseudo-photographs under the Protection of Children Act 1978.
- Deepfake intimate images: The Data (Use and Access) Act 2025 (section 138, in force 6 February 2026) created a new offence of intentionally creating a sexually explicit deepfake image without the subject’s consent.
- Statutory presumption of suspension: From March 2026, courts must suspend custodial sentences of 12 months or less unless specific conditions apply. This may affect lower-end sentences for Category C possession offences, though courts retain discretion.

Frequently Asked Questions
Is viewing illegal pornography a criminal offence in the UK?
Yes. Viewing indecent images of children amounts to “making” an image under section 1 of the Protection of Children Act 1978, even if you do not save or download the image. Viewing extreme pornography is covered by section 63 of the Criminal Justice and Immigration Act 2008. Both offences can result in imprisonment.
What is the difference between “making” and “possessing” an indecent image?
“Making” includes any act of viewing, downloading, or opening an indecent image – it does not require you to save it permanently. “Possession” requires proof that the image was within your custody or control and that you knew it was on your device.
Can I be charged if someone sends me illegal images without my knowledge?
It depends on the circumstances. If images are sent to you via WhatsApp or email and are automatically downloaded, you may have a defence if you can demonstrate you did not know the images existed and did not access them deliberately. However, if you opened, viewed, or saved the images, or were sent them knowing that there was a risk of this, you could face charges for making or possession. Seek legal advice immediately.
What happens if police find illegal images in my browser cache?
Images in a browser cache may support a charge of “making” (because they were loaded onto your screen at some point) even if they are difficult to access directly. However, a possession charge is harder to establish if you did not know the cached images existed. Forensic analysis of your device will usually reveal whether images were deliberately accessed.
Will I be placed on the Sex Offenders Register?
Some convictions for indecent image, prohibited image and extreme pornography offences trigger notification requirements, but whether they do depends on the specific offence, the offender’s age and, in some cases, the sentence imposed.
The length of time depends on your sentence: a custodial sentence of 30 months or more results in indefinite registration, while shorter sentences lead to registration periods of between 2 and 10 years. You can read more about the register in our guide to the Sex Offenders Register.
How do police investigate indecent image offences?
Police typically investigate these offences by analysing digital devices – including computers, phones, tablets, and cloud storage accounts. Specialist forensic units can recover deleted files, examine browser histories, and trace downloads. You can learn more in our article on how police uncover and investigate indecent images.
