How to open an HTML file on a vivo or iQOO phone

A teacher emails a quiz made with ChatGPT. A friend sends a Claude game on WhatsApp. You tap the .html file on your vivo or iQOO phone and get a screen of code, a page whose buttons do nothing, or a list of apps to choose from. This page covers what vivo's own help says about it: which file app your phone has, its Open with option, and where to set your browser. vivo's support site covers two systems, OriginOS and Funtouch OS. iQOO's own help site is built like vivo's and offers an OriginOS 7 preview for the iQOO 15, but we found no iQOO article on files or browsers, so the steps here are vivo's. Android's own steps and our full test are in How to open an HTML file on Android.

The vivo and Google help pages quoted here were read on November 6, 2026. vivo's articles carry no date, and most name a Funtouch OS version or none. Our device test ran in Google's Android emulator, not on a vivo or iQOO phone, so a label on yours may differ.

The quickest way on a vivo phone: open Convika's free HTML viewer in Chrome, tap Choose an .html file, and pick the file from your downloads. Your browser reads the file, and it isn't uploaded. If someone sent you a file you weren't expecting, ask them first, and turn off Run scripts before you choose it.

Sending a page you made? The upload box at the top of this page turns your file into a preview link without an account. That preview runs no scripts, so a quiz or game won't respond there yet: it's for checking the layout on your own phone. Click Keep this page — free, no card and sign up, and the page moves into your account, where its scripts run and you can publish it.

Which file app your vivo phone has

vivo's answer depends on the system version: "If the system version of your phone is below Funtouch OS 11, your phone supports File Manager. If the system version of your phone is Funtouch OS 11 or above, your phone supports Files by Google." On OriginOS, vivo's article on File Manager for its foldable phones says "OriginOS 7 comes with a fully upgraded File Manager". vivo doesn't say which file app earlier OriginOS versions have. Look for File Manager or Files among your apps.

What happens when you tap an .html file on a vivo phone

vivo's help doesn't say. What it does describe, in its article "How to change the open method of the file?", is how to pick the app yourself:

• File Manager: "Long press the file until the Menu pops up--select More--Open with, then select the App you desire to open the file."
• Files by Google: "Click the “three dots” icon at the right side of the file-- select Open with, then select the App you desire to open the file."

vivo doesn't say which apps that list holds for an .html file.

We tested a tap in Android's own Files app, not on a vivo phone, on October 21 and 22, 2026, on Android 16 in Google's Android Emulator, with Chrome 133. Android's own Files app showed Open with, listing Chrome and HTML Viewer, with Just once and Always under them:

• Chrome ran the whole page: its script, its button, a web font, and an image from the web.
• HTML Viewer showed the text and the CSS written inside the file. It ran no JavaScript, so the button did nothing, and it loaded nothing from the web.

Pick a browser, then Just once. Always makes that app open every .html file without asking, so pick it only for a browser. Android's own Files app isn't Files by Google, and the emulator has neither vivo's File Manager nor Files by Google, so we didn't see which apps their Open with lists, or whether they show the same buttons.

vivo Browser. vivo's answer to "How can I open a PDF file?" is "You can use the vivo browser that comes with the system to open a PDF file." That answer is about PDF files only. vivo doesn't say whether vivo Browser opens a saved .html file or runs its scripts, and we didn't test it: it doesn't come with Google's emulator.

Chrome. vivo's help names Chrome beside vivo Browser in an article on download settings, but none of the vivo help we read says whether Chrome comes on a new phone. If yours has it, it's the browser we saw run the page.

Open an HTML file on a vivo phone in 4 steps

These steps open the file in Chrome, where its scripts run. Nothing is uploaded.

1. Save the file to your phone

In Gmail, open the email and tap Download, as Gmail's Android help describes. In WhatsApp or another chat app, use that app's own save button; we didn't test those apps, so a button's name may differ. For a file sent with vivo's EasyShare app, vivo says to "Enter EasyShare--click clock icon at the top right corner--click “View storage location”" to see where it's saved.

2. Find it in File Manager or Files by Google

vivo doesn't say where a downloaded file goes. Use one of these:

• Files by Google: Recents. Google's help for the app: "Under the Recents section, you can view your recently added, downloaded, and modified files."
• File Manager: search. vivo: "tap “Search file/Search icon” displayed at the top of the file viewing interface, and enter the target name you want to search for."
• A file from vivo Browser. vivo's steps for its download settings start at "Vivo Browser>touch icon in the bottom>Select Downloads", so vivo Browser keeps its own list of downloads.

3. Open it with Chrome

Tap the file. vivo doesn't say what a tap does for an .html file; Google's Android help says "To open a file, tap it." If your phone asks which app to use, choose Chrome, then Just once, as in our emulator test.

If it opens in an app that shows code, or in a page that doesn't respond, go back and use vivo's route:

• In File Manager, long press the file until the menu pops up, select More, then Open with, and pick Chrome.
• In Files by Google, tap the three dots icon at the right of the file, select Open with, and pick Chrome.

In our emulator test, the page opened in Chrome with its scripts running, at an address that points into the phone.

4. If no browser is offered, use the HTML viewer

Open the HTML viewer in Chrome and tap Choose an .html file. In our emulator test, the file picker opened on Recent, which was empty: open the menu at the top left, choose Downloads, and tap the file. vivo doesn't describe this picker, so a label on your phone may differ. The viewer opens .html and .htm files up to 2 MB, and your browser reads them on the phone. Don't open a file you weren't expecting: ask the sender first, and turn off Run scripts before you choose it.

If the code came to you as text in a chat or an email, choose Paste code in the viewer instead, paste it, and tap Show the page.

Choose Chrome as your default browser on vivo or iQOO

vivo's English help gives the Default apps screen for Funtouch OS 11 and later: "Go to Settings > Apps & Notifications/Apps > Default apps". It names the home app there, not the browser. vivo's Indonesian help names the browser on the same screen: for Funtouch OS 11 and later, "Pengaturan > Aplikasi > Aplikasi default > Aplikasi browser" (Settings > Apps > Default apps > Browser app; the English labels are our translation). vivo's help doesn't give this route for OriginOS.

• What it changes. vivo doesn't say whether File Manager or Files by Google follows this setting for a saved .html file. Open with is the route vivo gives for opening one file in another app.
• If Chrome isn't listed. Install it from Google Play, then come back to Default apps. vivo's help doesn't say whether Chrome comes on the phone.
• If you tapped Always. The file then opens in that app without asking. vivo's help doesn't say how to undo that for a file type, and we didn't test it.

Whatever app is set, the HTML viewer works the same way. It's a web page you open in Chrome, so the file never goes to the app your phone picks.

Ways to open it on a vivo phone, compared

Why it shows code or a blank page

An app that shows the code is reading the file as plain text, not as a page; open it in Chrome instead. A page that looks right but doesn't respond was opened by an app that runs no scripts, as HTML Viewer did in our test. Missing pictures and styles usually mean that files saved next to the .html file didn't come with it. Why does my HTML file open as code (or a blank page)? checks each cause, and How to play an HTML game on your phone covers a game that opens but won't play.

Send a page that opens on any phone

If you're the sender, a link saves the other person every step above. They tap it in Gmail, WhatsApp, or Messages, the phone's browser opens the page, and its buttons work, on a vivo, a Galaxy, or an iPhone.

Frequently asked questions

How do I open an HTML file on my vivo phone?

Find the file in File Manager or Files by Google. In File Manager, long press it until the menu pops up, select More, then Open with, and pick Chrome. In Files by Google, tap the three dots at the right of the file, then Open with. In our Android 16 emulator test, Chrome ran the page's scripts. If no browser is offered, open Convika's free HTML viewer in Chrome and tap Choose an .html file. If someone sent you a file you weren't expecting, ask them first, and turn off Run scripts before you choose it. We didn't test a real vivo or iQOO phone.

Why doesn't my vivo phone have File Manager?

On Funtouch OS 11 and later, vivo says "your phone supports Files by Google" instead of File Manager; below Funtouch OS 11, it's File Manager. Look for Files among your apps. vivo's article on File Manager for its foldable phones says "OriginOS 7 comes with a fully upgraded File Manager".

Where do downloaded files go on a vivo phone?

vivo's help doesn't say. In Files by Google, Google's help says Recents shows "recently added, downloaded, and modified files". In File Manager, tap the search icon at the top and type the file's name. vivo Browser keeps its own Downloads list, which vivo's steps reach from the icon at the bottom of the browser.

How do I make Chrome open HTML files on vivo?

For one file, use Open with and pick Chrome: in File Manager, long press the file, then More, Open with; in Files by Google, the three dots, then Open with. To make Chrome your browser on Funtouch OS 11 and later, go to Settings > Apps > Default apps, where vivo's Indonesian help names the browser entry. vivo doesn't say whether its file apps follow that setting for a saved file.

How do I open an HTML file on an iQOO phone?

The same way as on a vivo phone, as far as we can tell. iQOO's own help site is built like vivo's, but we found no iQOO article on files or the default browser. Find the file in File Manager or Files by Google, use Open with, and pick Chrome. We didn't test an iQOO phone.

Why does my HTML file show code on my vivo phone?

The app that opened it is reading the file as plain text instead of running it as a page. A browser is what turns HTML into a page. Open the file again with Open with and choose Chrome, or paste the code into Paste code in an HTML viewer and tap Show the page. If the sender can give you a link instead, that opens straight in your browser.

How do I send an HTML file so it opens on a vivo phone?

Send a link to the published page, not the file. Put the file on a host that runs its scripts, then paste the address into the chat or the email. With Convika, the upload box makes a preview link without an account, with scripts off, for checking the layout. Keep the page on the Free plan and publish it, and the link opens in any phone's browser with its buttons working.
