TL;DR: Viki does not provide an official option to export subtitles as standalone SRT files. Its official Offline Viewing feature keeps the video and subtitles inside the mobile app. If you specifically need an SRT file on Windows or Mac, use a separate desktop workflow for a supported title.

For local viewing on your PC, first decide whether you need a standalone SRT file, an MP4/MKV video paired with external subtitles, or only app-managed mobile playback. watch on your PCPart 2
When checking Viki subtitles, treat the subtitle language, episode version, and timing as one matching task. A standalone SRT is useful when you need timed text for an external player or want to inspect a translation independently. Viki's official Offline Viewing feature instead keeps downloaded video and subtitles inside its mobile app.
Can I Download Subtitles from Viki?
Viki does not provide an official feature for exporting subtitles as standalone SRT files. Its official Offline Viewing feature downloads eligible video and subtitles for playback inside the Viki mobile app.
An SRT file contains timed subtitle text, while an MP4 or MKV file contains video that can be paired with external subtitles. If you specifically need an SRT on Windows or Mac, a separate desktop workflow may provide that output for supported episodes. Third-party subtitle extraction depends on the page, title, and current technical compatibility, so do not assume that a generic subtitle tool works with every Viki episode.
How to Download Viki Videos with SRT Subtitles on PC/Mac?
Core Viewpoint: An SRT file contains subtitle text and timing, not video. Viki's official Offline Viewing feature provides app-managed playback rather than an independent subtitle file.
The official Viki website does not provide a Viki download for PC feature or a standalone-SRT export. A separate desktop workflow can save supported video together with selected subtitles as local files when those output options are available. Use the desktop route when the separate SRT itself is important for your player, language study, or subtitle checking.
Save Multilingual Subs with KeepStreams
With KeepStreams for Rakuten Viki, you can download Viki videos in MP4 or MKV for supported titles and select from the subtitle options available for that episode. Separate SRT output is available when offered by the current title and workflow. Choose the needed language before downloading, then keep the resulting subtitle file paired with the matching episode.
Start by downloading and installing KeepStreams from its official download page.
Use third-party local-file tools only where your specific use is permitted under Viki's terms and applicable law, and do not redistribute saved video or subtitle files.
Step 1
Choose Rakuten Viki from among the supported services.
Click on VIP Services, choose Rakuten Viki, and sign in to the account that has access to the episode.
Step 2
Play the target Viki video and wait for analysis. If analysis does not start, click the orange Download button.
In the settings window, choose MP4 or MKV, select an available subtitle language, and choose separate SRT output when that option is available for the episode. Confirm the language before downloading; selecting the correct track here is easier than diagnosing the wrong subtitle after the video and SRT have already been paired.
Step 3
Download the video and subtitle files.
Click Download Now. In the Downloads section, you can view the current task and open the completed video and subtitle files.
Before relying on the files offline, load the SRT with the corresponding video in a player that supports external subtitles. Start with the opening dialogue. If the displayed subtitle belongs to a different cut or edit of the episode, first confirm that the video and SRT match the same episode version rather than immediately shifting the subtitle timing.
If the subtitle language itself is wrong, check the selected subtitle track first. Once the episode version and language match, check timing at several points across the video. A simple timing offset cannot reliably fix an SRT created for a different episode version.
If analysis fails, first confirm that the title plays normally in the signed-in Viki account. Then install the current KeepStreams release and use its support or troubleshooting route if the same title still cannot be analyzed.

How to Download Rakuten Viki Videos with Subtitles in the App?
Viki Offline Viewing is currently available to eligible Viki Pass Plus subscribers and users with purchased rental titles on Android app version 9.0+ and iOS app version 15.0+. Offline downloads are limited to one authorized mobile device per user account.
Official downloads provide app-managed playback rather than standalone SRT files. Downloaded subtitles are based on your selected default subtitle language and the subtitle completion percentage available when the episode is downloaded. If Viki subtitles are updated later, you need to download the episode again to get the newer subtitle version.
The official app can download multiple individual videos at the same time, but Viki currently does not provide one button for downloading an entire series.
- Sign in to the Viki mobile app with eligible Viki Pass Plus access or access to a purchased rental.
- Select your preferred default subtitle language and check the episode's current subtitle availability.
- Open an eligible title and tap the download icon.
- Play the downloaded episode from the Download tab.
- If the subtitles are updated later, re-download the episode to receive the newer subtitle version.
Official Viki downloads are available only for a limited period, and the app displays a countdown for downloaded titles. For non-rental titles, an expired download can be downloaded again while eligible Viki Pass Plus access remains active.
For rentals, you normally have 30 days to access the rented title. When you use Offline Viewing, the 48-hour rental period begins when the title is downloaded to the device or when playback begins, whichever happens first. See How long does a Viki download last? for additional examples.
FAQs
Q1. Can I download subtitles from Viki for free?
A1. Viki does not provide an official free standalone-SRT export. Official Offline Viewing is available to eligible Viki Pass Plus subscribers and users with purchased rental titles, and its subtitles remain inside the app-managed download rather than becoming separate video files or SRT files.
Q2. Why does my downloaded SRT not show up in my video player?
A2. An SRT is a separate timed-text file. Open the matching episode in a player that supports external subtitles, load the SRT manually if necessary, and confirm that the subtitle file matches both the episode version and selected language.
Q3. Do official Viki downloads expire?
A3. Yes. Viki displays the remaining viewing time for downloaded titles. Non-rental titles can generally be downloaded again after expiry while eligible Viki Pass Plus access remains active. Rentals normally provide 30 days to access the title, while downloading it or beginning playback starts the 48-hour rental window.
Q4. Is personal use enough to make downloading Viki subtitles legal?
A4. No. Personal use alone does not automatically establish permission. The specific use, Viki's terms, applicable law, and the content involved all matter.
Q5. What should I check if a downloaded subtitle file skips lines?
A5. First compare the same scene in the current Viki episode. If the line is also missing online, the difference is not limited to the local SRT. If the online subtitle is present, confirm that the SRT matches the same episode version and language, then check timing at several points in a compatible player. For KeepStreams output issues, install the current release and use its support or troubleshooting route.
Conclusion
Quick choice: Use Viki's official mobile download when you only need offline playback inside the app. Use a separate desktop workflow when you specifically need a local MP4/MKV file and a separate SRT subtitle file.
The most important distinction is the output. Viki's official Offline Viewing keeps eligible episodes and subtitles inside its mobile app, while a desktop workflow can provide local video and subtitle files for supported titles. If you need an SRT for translation checking, an external player, or closer subtitle-version control, KeepStreams for Rakuten Viki is one desktop option.
Whichever route you use, check the subtitle language, episode version, and timing together. Many apparent timing problems are actually caused by pairing an SRT with the wrong episode cut or subtitle track.
