How to add subtitles to a video on Android without
Chrome on Android runs Add Subtitles to Video entirely on-device. Here's the exact flow for videos on a phone.
One reason people install third-party apps on their phone is that they don't realise the same tool runs perfectly in mobile browsers. Add Subtitles to Video is browser-only — no app store, no install — and it works exactly the same on Android as it does on a laptop.
Try it now: Add Subtitles to Video — Everything happens locally in your browser — your file never leaves your device.
Step-by-step on Android
- Open Chrome and navigate to Add Subtitles to Video.
- Tap "Choose file" or use Chrome's built-in file picker.
- Pick the video from Photos, Downloads, Google Drive, or any other connected location.
- Adjust the options for Add Subtitles to Video and start processing.
- Save the output — Chrome puts it in your Downloads folder by default.
- Share via any app — long-press the file in your file manager or use the Downloads menu.
Useful Android-specific tricks
- Install Add Subtitles to Video as a PWA — Chrome will offer "Add to home screen" once you've used the page a couple of times. The icon behaves like a native app.
- Direct share from any app — most file managers and gallery apps let you "Open with Chrome", which sends the file straight into Add Subtitles to Video.
- Background-tab caveat — older Android phones may pause heavy processing if Chrome goes to the background. Keep the tab visible for big files.

Why a browser tool beats most native apps for this
Native apps that add subtitles to videos are almost all just wrappers around browser-class libraries. They usually upload your file to their server, which is slower, less private, and sometimes paywalled. Add Subtitles to Video does the work directly in your phone's browser engine — same code path that would run if you were on a desktop, no upload, no signup, no daily limit.
Frequently asked questions
Is my video private when I use a browser tool?
Yes — more private than most apps, because nothing is uploaded. The video is processed entirely inside the browser tab and is gone the moment you close it.
Will processing drain my battery?
Heavy video work uses your phone's CPU just like any other intensive app. For most videos the job finishes in seconds; a 100MB video might use a noticeable but small slice of battery.
Can Add Subtitles to Video access my Google Photos?
Only when you pick a file through the standard system file-picker. The browser sandbox prevents any app — including Add Subtitles to Video — from reading your library without an explicit selection.
Why isn't there a "Add Subtitles to Video" app on the Play Store?
Because there doesn't need to be. Mobile browsers run the same WebAssembly the desktop site uses. Shipping a native app would mean maintaining two codebases for the same feature.
