You can mark up PDFs in Chrome on Android — here's how

Tom's Guide19-06-2025
When you're browsing the web in Chrome on your Android phone, you want the experience to be as seamless as possible. To that end, visiting a website containing a PDF has been something of a bugbear, with the browser insisting that you download the file and open it in a PDF viewer.
But that's now a thing of the past. As you're about to discover, Chrome now lets you view PDFs directly in the browser. That means no more clogging up your Downloads folder or tapping more times than necessary. And if that wasn't good enough, you can now annotate those PDFs too. One day, we hope you'll be able to fill in forms as well.
So, let's take a look at how you can view and annotate PDFs in Chrome, while also covering what to do if you still want to download a PDF.
Here you will discover how to get the most out of PDFs within the Chrome browser.
Browse the web as normal using Chrome on your Android phone and tap a PDF link if you see one. The PDF will instantly appear in the browser.
With the PDF open in Chrome, you can navigate it in the same way as you would any webpage. For example, you can scroll up and down, pinch open and closed to zoom in and out, or touch-and-hold text to select it.
You can also tap the three-dot button in the top-right corner of the screen, select Find in page and enter a search term to look for text in a PDF.
To annotate the PDF, tap the blue button in the bottom-right corner of the screen.
You will, by default, be able to instantly use the pen to draw lines on the screen. This icon is the one furthest to the left at the bottom of the screen. If you tap the pen icon, you can select a different color or use the slider to change its thickness.
You also have access to a highlighter — tap the highlighter icon which is the second from the left.
Once selected, just find text or a part of the PDF that you would like to highlight and move your finger across the screen.
If you have made an error with your annotations, you can tap the Eraser icon (third from the left) and swipe your finger over the lines you've drawn or text you've highlighted to remove your marks.
You can also tap the Undo or Redo icons (the next two along). As a bonus, you can tap the eye icon to hide or show your annotations.
When you are finished annotating the PDF, select Save Copy in the top-right corner and you can upload the document to Drive (or any other location you choose — select the Location dropdown menu).
You can also tap and change the filename. Select Upload.
You may not actually want to work with a PDF in Chrome but, don't worry, Google will let you download it. There are two ways.
Just tap the three-dot menu in the top-right corner of the screen and select the Download icon in the toolbar at the top of the menu (it looks like a downward arrow).
You cannot view PDFs in Chrome if you are in Incognito mode (you can enter Incognito mode if you tap the three-dot menu icon in the top-right corner of the screen and select New Incognito tab).
When you try to open a PDF in Chrome in Incognito mode it will automatically prompt you to download the file so give it a name, select the destination folder and select Download.
And there you go. You now know how to open and annotate PDFs in Chrome on Android.
There are other ways of getting the most out of a PDF, though. You can learn how to sign documents on Android, for example, and how to save to a web page as a PDF. You may also want to discover how to scan documents on Samsung Galaxy phones, too.

Chrome isn't for sale, but Perplexity just offered $34.5 billion anyway

Edgar Cervantes / Android Authority TL;DR Perplexity AI has made a $34.5 billion cash offer for Google's Chrome browser. Google isn't selling Chrome and is appealing a court ruling that could one day force its sale. Perplexity says it has funding lined up and would keep Chrome open source with no search engine changes. Google might be forced to sell its Chrome browser in the future, thanks to a US court ruling that found it held an unlawful monopoly in online search. But while the case is still crawling through appeals, Perplexity is making an ambitious bid to swoop in early to buy it. Don't want to miss the best from Android Authority? Set us as a preferred source in Google Search to support us and make sure you never miss our latest exclusive reports, expert analysis, and much more. As reported by Reuters, Perplexity AI has tabled an unsolicited $34.5 billion cash offer to Google for Chrome, despite the fact that it isn't actually for sale yet. The three-year-old company is worth less than half that itself, but says it has unnamed backers ready to cover the cost. CEO Aravind Srinivas has a taste for headline-making bids. Earlier this year, he offered to merge with TikTok's US arm to help solve Washington's concerns about Chinese ownership. Perplexity's pitch includes keeping Chrome's underlying code open source, investing $3 billion over two years, and leaving its default search engine untouched. The startup argues this would preserve user choice and avoid future antitrust headaches. It's a bold target. Chrome has over three billion users and is central to Google's AI search push, making it unlikely the company would let it go until its legal avenues are completely exhausted. Analysts think that the fight could drag on for years, even if a court eventually orders a sale. Still, the fact that Perplexity — and reportedly OpenAI, Yahoo, and Apollo Global Management — are circling Chrome shows just how valuable the browser has become in the AI race. Follow

AI startup Perplexity offers to buy Google Chrome for $34.5B

San Francisco-based AI startup Perplexity offered to buy Google Chrome in a deal for tens of billions of dollars after it was valued at around $18 billion last month but gave a $34.5 billion unsolicited offer. File Photo (2018) by Sascha Steinbach/EPA Aug. 12 (UPI) -- AI startup Perplexity has offered to buy Google Chrome in a deal for tens of billions of dollars. The San Francisco-based artificial intelligence software company in July was valued at about $18 billion. The company made a $34.5 billion unsolicited offer to buyout Google's Chrome browser, The Wall Street Journal first reported. In addition, Perplexity said it would commit to keeping Google's open-source Chromium project. The Google Chrome browser, which launched in 2008, has a reported valuation of anywhere between $20 billion to $50 billion. Perplexity said multiple investors have agreed to back the deal despite its current valuation as it battles for supremacy in the AI marketplace with bigger names such as OpenAI and Mark Zuckerberg's Meta, which approached the company this year about its own potential acquisition of Perplexity. The AI-powered search engine Perplexity launched its AI-powered browser Comet last month. The unsolicited offer comes after the U.S. Department of Justice had suggested Google divest itself of Chrome stemming from the antitrust lawsuit Google lost in 2024 that said it violated U.S. antitrust law as a monopoly in search and text advertising. But Google officials have yet to reveal how the search engine giant plans to adjust. Google did not immediately reply to UPI's request for comment.

IBM, Google claim quantum computers are almost here after major breakthroughs: ‘It doesn't feel like a dream anymore'

The decades-long quest to create a practical quantum computer is accelerating as major tech companies say they are closing in on designs that could scale from small lab experiments to full working systems within just a few years. IBM laid out a detailed plan for a large-scale machine in June, filling in gaps from earlier concepts and declaring it was on track to build one by the end of the decade. 'It doesn't feel like a dream anymore,' Jay Gambetta, head of IBM's quantum initiative, told Financial Times.

AFP via Getty Images 'I really do feel like we've cracked the code and we'll be able to build this machine by the end of the decade.' Google, which cleared one of the toughest technical obstacles late last year, says it is also confident it can produce an industrial-scale system within that time frame, while Amazon Web Services cautions that it could still take 15 to 30 years before such machines are truly useful. Advertisement Quantum computing is a new kind of computing that doesn't just think in 0s and 1s like today's computers. Instead, it uses qubits — tiny quantum bits — that can be 0, 1, or both at the same time. This lets quantum computers explore many possibilities at once and find answers to certain complex problems much faster than normal computers. 4 IBM headquarters in Armonk, NY, where the company leads development of its quantum computing research. Askar – Advertisement Quantum computing could speed up the discovery of new drugs and treatments, make artificial intelligence systems faster and more capable and improve the accuracy of market predictions and fraud detection in finance. It could also dramatically improve efficiency in areas like traffic routing, shipping, energy grids and supply chains while driving green innovation by helping design better batteries, cleaner energy systems and more sustainable technologies. But scaling them up from fewer than 200 qubits — the quantum version of a computing bit — to over 1 million will require overcoming formidable engineering challenges. 4 Google's Mountain View campus, home to its Quantum AI division pursuing a surface-code design to reach industrial-scale systems. Sundry Photography – Advertisement Qubits are inherently unstable, maintaining their special quantum states for only fractions of a second, and adding more of them can create interference that scrambles calculations. Even if the fundamental physics problems are solved, the industry still faces the task of industrializing quantum technology. This means building chips that can house large numbers of qubits, and developing much bigger refrigeration units to keep the systems at near absolute zero. 4 Quantum computing could speed up the discovery of new drugs and treatments, make artificial intelligence systems faster and more capable and improve the accuracy of market predictions. AFP via Getty Images Systems using superconducting qubits, like those from IBM and Google, have made some of the fastest progress but require extreme cooling and are difficult to control. Meanwhile, some companies are betting on radically new qubit designs. Amazon and Microsoft claim to have harnessed a new state of matter to produce more reliable components, although these are still in early development. 'Just because it's hard, doesn't mean it can't be done,' Mark Horvath, an analyst at Gartner, told FT.
