Investing can become complicated very quickly.
There are individual shares to research, results to follow, broker notes to read, and market swings to understand.
But not every investor wants to build a portfolio company by company.
For those who want a simpler way to invest, ASX exchange traded funds (ETFs) can do a lot of the heavy lifting.
Here are three ASX ETFs to consider buying if you want to keep things simple.

Vanguard MSCI Index International Shares ETF (ASX: VGS)
The Vanguard MSCI Index International Shares ETF could be a good starting point.
This fund gives investors exposure to a large collection of companies listed across developed markets.
I think this is valuable for Australian investors because the local share market is quite concentrated. Banks, miners, supermarkets, and a handful of healthcare and industrial names do a lot of the work.
The Vanguard MSCI Index International Shares ETF changes that in one trade. It gives investors access to global companies involved in technology, healthcare, financial services, consumer products, industrials, and communications.
That makes it a simple way to move beyond Australia without having to choose which overseas shares to buy.
iShares S&P 500 ETF (ASX: IVV)
The iShares S&P 500 ETF is another ASX ETF that can keep investing simple.
This fund tracks the S&P 500 Index, which is where you'll find 500 of the largest listed companies in the United States.
That includes many of the businesses already shaping the global economy through cloud computing, artificial intelligence, software, payments, healthcare, consumer brands, industrial products, and digital advertising.
There is some overlap with the Vanguard MSCI Index International Shares ETF because the United States is such a large part of global share markets.
But the iShares S&P 500 ETF gives investors a more direct exposure to corporate America and the S&P 500, which has been one of the world's most important long-term wealth-building markets.
For investors who want a simple, low-fuss way to own leading US companies, this ETF could be worth considering.
Betashares Global Cybersecurity ETF (ASX: HACK)
A third ASX ETF to look at is the Betashares Global Cybersecurity ETF.
It gives investors access to companies helping protect networks, cloud systems, devices, data, payments, and digital identities.
This could be a good place to be. As more of the economy moves online, more money needs to be spent keeping it safe.
Businesses now rely on cloud software, remote access, online payments, artificial intelligence tools, and connected systems. None of that works properly if security fails.
The Betashares Global Cybersecurity ETF will not be as diversified as a broad global ETF, so investors should expect more ups and downs. But as a long-term theme, cybersecurity looks like a problem that companies cannot afford to ignore.
