Tech Advisor, previously known as PC Advisor, is a consumer tech website and digital magazine published by Foundry. Foundry was previously a subsidiary of International Data Group (IDG, Inc.), which was acquired by Blackstone in 2021, but in March 2025 Foundry was acquired by Regent. Foundry also produces Macworld, PC World and TechHive.

Tech Advisor is a mobile brand, offering reviews and buying advice for the best phones, tablets and wearables, and hacks for improving your life using the technology that is always with you. These applications extend into controlling smart home tech and streaming, which are also covered by the website.

It originated with the 1995 launch of a localised UK and Ireland edition of the US-based PC World magazine. This was renamed PC Advisor to avoid confusion with an unrelated magazine and retailer. In 2017, around the time of the end of the print edition, the PC Advisor website was rebranded as Tech Advisor.

Tech Advisor started out as techAdvisor.co.uk, a spin-off website "from the editors of PC Advisor and MacWorld".

In March 2017, the online version of PC Advisor- still at the "pcadvisor.co.uk" domain- adopted the Tech Advisor brand. In June 2017- around the same time that publication of PC Advisor's print edition ended- the rebranding from PC Advisor to Tech Advisor was completed with the move of the main website from "pcadvisor.co.uk" to "techadvisor.co.uk" (although the PC Advisor name was retained as part of Tech Advisor for certain pages and uses).

Tech Advisor continues to operate as both a website and monthly digital magazine focused on consumer and small business technology buying advice.

On 24 August 2020 a formal announcement was made that the Tech Advisor forums would close permanently on Wednesday 2 September 2020.

In April 2021, Tech Advisor moved from a UK ccTLD (.co.uk) to a gTLD (.com) domain, focused primarily on smartphones, tablets, and wearables, but also covering smart home and appliances, and entertainment.
