SubLoader

Load, capture, and customize subtitles for YouTube, Dailymotion, Netflix, and Prime Video, with sync and dual subtitles.

SubLoader Bring your own subtitles, find them online, or capture available subtitles from YouTube, Netflix, and Prime Video. SubLoader is a Chrome extension that lets you load local subtitle files directly over supported videos, search for subtitles online through OpenSubtitles, and capture, load, or download available subtitle tracks from supported streaming platforms. It gives you control over subtitle timing, appearance, translation, and playback across YouTube, Dailymotion, Netflix, and Prime Video. **Load your own subtitle files** Open a supported video, launch SubLoader, choose your subtitle file, and start watching. SubLoader processes local subtitle files directly in Chrome and supports multiple common subtitle file formats. **Find subtitles online** Search for subtitles directly from SubLoader by title, year, season, episode, and language. Search results can also display FPS match information to help you choose a subtitle file that better matches the video. You can load a subtitle directly into SubLoader or download it for later use. Online subtitle search is provided through OpenSubtitles, a separate third-party service. OpenSubtitles may apply its own account, download, and usage limits. **YouTube subtitles** Discover available subtitle tracks from YouTube videos, including original, automatically generated, and automatically translated subtitles. Capture available subtitles directly from the YouTube player and load them into SubLoader for viewing and customization. Captured subtitles can also be downloaded in multiple supported subtitle formats. YouTube subtitle capture and loading are available without a SubLoader account. Downloading captured subtitles requires a Free or Premium account. **Netflix and Prime Video subtitles** Capture available subtitle tracks from supported Netflix and Prime Video videos. Load captured subtitles directly into SubLoader, download them for later use, or convert them into supported subtitle formats. A SubLoader account is required for subtitle downloads and eligible conversions. Subtitle availability may vary depending on the video and streaming platform. **Dual subtitles** Display two subtitle tracks at the same time. Primary and secondary subtitles can be customized independently, making dual subtitles useful for language learning, translations, or comparing subtitle tracks. **Fine-tune subtitle timing** If subtitles appear too early or too late, SubLoader provides quick synchronization controls. Move subtitles earlier or later in small or large increments, or reset the delay instantly. Save Synced lets you save a subtitle file with your synchronization adjustments applied. **Video seek controls** Jump backward or forward 10 seconds in the video directly from SubLoader for convenient playback navigation. **Customize subtitle appearance** Adjust how subtitles look for different videos, displays, and viewing preferences. Available controls include font family, font size, text stroke, text color, bold text, vertical position, and background level. Primary and secondary subtitle tracks can be styled separately when Dual Subtitles is enabled. Save your preferred subtitle appearance settings as presets and quickly restore them whenever needed. **Word Lookup** Look up word definitions and pronunciation information while watching videos. Word Lookup can help you understand unfamiliar words without leaving your viewing experience. **Read Subtitles** Have subtitles read aloud using available browser and system voices. Select your preferred voice and language, and adjust speech speed and volume. Primary and secondary subtitle tracks can be configured independently. Voice availability depends on the voices installed on your device. **AI Subtitle Translation (Premium)** Translate subtitle files into more than 100 languages using supported translation services. SubLoader provides multiple translation options, including services that may require your own API credentials. AI Subtitle Translation is available to Premium subscribers. **Free and Premium accounts** SubLoader offers Free and Premium plans. Free accounts include access to local subtitle tools, online subtitle search, dual subtitles, appearance customization, Word Lookup, Read Subtitles, and other available Free features. Free accounts also receive 20 subtitle downloads per month, shared across YouTube, Netflix, and Prime Video. Premium includes unlimited eligible YouTube, Netflix, and Prime Video subtitle downloads and conversions, AI Subtitle Translation, and everything included in Free. Current plan benefits and download usage can be viewed through SubLoader. **Per-video subtitle memory** SubLoader remembers subtitles for videos during the current tab session, so if you navigate away and return to the same video, the subtitle can be restored automatically. **Privacy-focused local subtitles** SubLoader processes local subtitle files directly in Chrome. When you use Find Subtitles Online, SubLoader communicates with OpenSubtitles to perform searches, authentication, and subtitle downloads. YouTube, Netflix, and Prime Video subtitle features access available subtitle data from their respective platforms. SubLoader accounts are used to manage account access, plan benefits, and applicable download allowances. Some optional features, including online translation, communicate with third-party services when used. For additional information, see the SubLoader Privacy Policy. **How to use SubLoader** 1.
