Netflix is the most popular streaming service in the world. It offers loads of movies and series that you can watch on smartphones, tablets, and computers. Over the years, Netflix has become a one-stop destination for watching movies and TV shows in different languages.

While the user base of Netflix is quite diverse, the platform offers subtitles in limited languages for most movies and series. Suppose you want to view a Korean Drama on Netflix with French subtitles. However, you found that French subtitles are unavailable for that Korean Drama. In such a case, you might wonder if adding custom subtitles to Netflix is possible.

Well, you can add subtitles to Netflix, and there are two different methods to do the same. This guide will help you learn both methods available for adding custom subtitles to Netflix. So, let's get started!

Method 1. Upload Your Custom Subtitle to Netflix

Before proceeding with this method, you must remember that it only works if you are a Netflix Premium user. Now, let's discuss how to add subtitles to Netflix with this method.

Key Steps to Follow:

Below are the steps for adding custom subtitles to Netflix.

Step 1 First of all, you need to install and add Language Learning with Netflix & YouTube™ extension to your web browser (Chrome or Edge).

Step 2 Make sure the extension is activated.

Step 3 Download the .srt file that contains the subtitles in your preferred language for a particular movie or TV show.

Step 4 Open Netflix on a Chrome or Edge browser and sign into your account.

Step 5 Play the movie or TV show for which you have downloaded the subtitles.

Step 6 Within the Netflix player, you will see a settings icon left to the Subtitles icon. Click on it.

Step 7 Among the various setting options, you need to choose the screen and find the one with the label "Lower Subtitles (Mother Language)". You need to click on its field and select the "Upload Subtitle" option.

Step 8 You will see a pop-up window at the top of the screen where you need to click the "Choose File" button.

Step 9 You then need to navigate to the directory on your computer where you have downloaded the subtitles file, select it, and click the "Open" button.

Step 10 Click the "Okay" button to upload the subtitles to Netflix.

Step 11 Close the settings window and play the video. You can view the uploaded subtitles at the bottom of the player.

Method 2. Add Custom Subtitles to Netflix with Extensions

If you're not a Netflix Premium user, you can still add subtitles to Netflix with the help of certain browser extensions. We'll list them down and discuss the steps for using one of them; the basic steps for using all such extensions are pretty much the same.

1. Substital

Supported web browsers: Chrome | Firefox | Edge

Substital is among the most popular extensions that allow you to add subtitles to several online on-demand video streaming platforms, including Netflix. It has more than 100K users on the Chome Web Store.

Key Features

  • Offers a built-in subtitles search feature.
  • Supports .srt files and .zip files containing subtitles in the .srt format.
  • You can manually sync the subtitles with the video.
  • It allows you to customize the appearance of subtitles.

Steps to Add Custom Subtitles to Netflix with Substital

Following are the key steps to add custom subtitles to Netflix using the Substital extension:

Step 1 The first thing you need to do is to download and install the Substital extension on your browser.

Step 2 Open Netflix on the same browser and log in to your account.

Step 3 Play the movie or episode from a TV series for which you want to add custom subtitles.

Step 4 Download the subtitles file for the same movie or episode in your preferred language from the web.

Step 5 Now open the extensions menu in your browser and click on the Substital icon.

Step 6 You will see the name of the movie or TV show that you are watching on Netflix. Click on it.

Step 7 In this step, you need to drag and drop the subtitle file from your system (that you downloaded earlier) to the browser window.

Step 8 Finally, you can notice that the subtitles are loaded in the Netflix player.

2. Super Netflix

Web browsers: Chrome

Super Netflix is yet another reliable extension to add subtitles to Netflix. Apart from adding custom subtitles, this extension allows you to change the video playback speed. Like Substital, the Super Netflix extension on Chrome Web Store also has 100K+ users.

Key Features

  • It can help you avoid spoilers by blurring images and episode descriptions.
  • You can use the extension to skip intros automatically.
  • Offers 5 different video modes.
  • You get the option to change the Netflix streaming server.

3. Netflix SubStyler: customize subtitles

Web browsers: Chrome

Unlike the other two extensions mentioned above, Netflix SubStyler only allows you to change the styling of subtitles on Netflix. However, the thing that makes this extension worthy of your attention is that it comes loaded with several customization options.

Key Features

  • You can choose a custom text color for the subtitles either with the help of an in-built color picker or by entering the RGB value of the color.
  • The extension lets you add text outlines and change the size of the text.
  • You can even add a text background and change its color and opacity.

Bonus Tip: How to Edit and Add Subtitles to Videos Available Offline

In certain cases, you may want to edit the subtitles of videos probably because either the subtitles are not available for a certain part of the video, or they are not correct. So, if you want to edit subtitles of videos that you have downloaded with ease, you can consider using Wondershare Filmora.

Add Custom Subtitles with Filmora: A Step-by-Step Guide

If you want to add subtitles to any video using Filmora, you simply need to follow the steps mentioned below. Please note that for this tutorial, we'll be using Filmora 11.

Step 1 Launch the Filmora app on your computer and create a new project.

Step 2 You can simply click the "Import media" button and load the video onto it.

Step 3 Hover over the video's thumbnail and click on the (+) button to add it to the timeline.

Step 4 Now, you need to play the video and find the section of the video where you need to add subtitles. Pause the video and add a mark by pressing the M key on your keyboard. You can also do the same by clicking the marker button, which is located beside the microphone icon in the top right of the timeline tab.

Step 5 To add the subtitle, you need to click on the "Titles" button that you can see at the top of the Filmora window. You can see several subtitle templates available there.

Step 6 Download, preview, and choose a subtitle template that seems most appropriate.

Step 7 You can then drag and drop the subtitle to the timeline above the video timeline. You can also trim the subtitle length from any side of the subtitle timeline box.

Step 8 You need to double-click on the subtitle timeline box to add custom text, change font size, color, and alignment, and add animations.

Step 9 Once done, you can click on the "Ok" button to save the changes.

Step 10 Similarly, you can add subtitles for different sections of the video.


If you want to add custom subtitles to Netflix movies and TV shows, you can achieve the same with the two different methods mentioned above. For the first method to work, you must be a Netflix Premium user. On the other hand, the second method will work fine even if you aren't a Netflix Premium user. Also, you can add custom subtitles to any offline videos using the Wondershare Filmora video editor.
