How to Extract Subtitles from a Video

Upload Your Video File

Drag and drop your MKV or WebM file into the upload area, or click to browse and select it from your device. Files above 500 MB are refused. MP4 and MOV are not read here, because their subtitle tracks are not supported.
Select the Subtitle Track

The tool lists every subtitle track it finds in the container, with the language the file records for it. Pick the one you want from the dropdown. A single file often carries several languages plus a forced or SDH track.
Preview the Extracted Subtitles

Review the cue text and the timestamps in the preview panel. Check the first and the last cue against the video, so you know the timing is right before you save the file.
Download SRT or VTT

Save the track as SRT for the widest player support, or as WebVTT for the HTML video element and web players. You can also copy the text straight into a text editor or a subtitle editor.

Common Use Cases

Translate Subtitles into Another Language

Extract the original subtitle track from a foreign-language film or lecture, then translate the SRT file into your target language using a translation tool or manually edit the text while keeping the original timestamps intact.

Create Transcripts for Accessibility

Pull subtitles from recorded webinars, conference talks, or educational videos to generate readable text transcripts. These transcripts improve accessibility for deaf and hard-of-hearing viewers and serve as study notes.

Edit and Retime Subtitles

Extract existing subtitles from a video that has timing issues or formatting errors, fix them in a subtitle editor, and re-embed the corrected SRT file back into the video container.

Repurpose Video Content as Text

Convert subtitle tracks from tutorials, podcasts, or presentations into blog posts, articles, or social media content. The extracted text preserves the spoken dialogue, saving hours of manual transcription.

Why use our Subtitle Extractor?

Our subtitle extractor reads the subtitle tracks stored inside a video file and saves them as a standalone caption file. It parses MKV and WebM containers with its own Matroska reader, lists every subtitle track it finds so you can pick the language you want, and exports the selected track as SRT or WebVTT. SRT, WebVTT and ASS/SSA text tracks can all be read. MP4 and MOV subtitle tracks are not supported: re-mux those files to MKV first, or pull the track with a desktop tool such as MKVToolNix or FFmpeg. Files up to 500 MB are accepted, and the video itself stays on your device.

Subtitle extraction is the process of reading the text tracks stored inside a video container and saving them as a standalone caption file. This tool parses MKV and WebM files with its own Matroska reader, lists the subtitle tracks it finds, and writes the one you pick as SRT or WebVTT: SRT for the widest player support, WebVTT for the HTML video element. SRT, WebVTT and ASS/SSA text tracks can all be read.

Two limits are worth knowing before you start. MP4 and MOV subtitle tracks are not supported, so re-mux those files to MKV with MKVToolNix or FFmpeg first, or pull the track with a desktop tool. And hardcoded subtitles, the kind rendered into the video frames during encoding, are part of the picture: no extractor can recover them as text. Soft subtitles are the ones that can be extracted, edited, translated or removed. To see what tracks a file actually contains before you start, try the Video Metadata Extractor, and to re-time a track you have already saved, use the Subtitle Shifter.

The whole job runs in your browser. The tool code uploads nothing, there is no queue, and the only cap is the 500 MB the page will accept. That makes it usable for confidential footage, corporate training videos, and anything you would rather not hand to a third-party service. The page itself loads analytics and ad scripts, as most websites do; they are separate from the tool code.

How it compares

Most online subtitle extractors require you to upload your video to a remote server, which introduces privacy risks, file size limits, and processing queues. Services like Subtitle Edit Online and SubtitleBee cap usage or require account registration. Desktop applications such as MKVToolNix and FFmpeg read every container and every subtitle codec, and they remain the right answer for MP4 and MOV files or for image-based tracks such as PGS and VobSub. This tool covers the common case, MKV and WebM text tracks, with zero setup, no account and no upload.

For users who also need to trim, convert or re-time their video files, FindUtils offers browser-based tools including the Video Trimmer, the Video Format Converter and the Subtitle Shifter. Combined, they cover common caption work without installing any software.

Tips for Best Results

Make sure your video has embedded soft subtitles, not hardcoded (burned-in) text overlays, which cannot be extracted by any tool.
MKV is the container this tool reads, and it is also the one that usually carries the most subtitle tracks. If you have a choice of source file, take the MKV.
After extraction, open the SRT file in a plain text editor to verify timestamps and fix any encoding issues with special characters.
For videos downloaded from streaming platforms, subtitles are often delivered as separate sidecar files rather than embedded tracks. Check the download folder for .srt or .vtt files first.
If the tool reports no subtitles for an MP4 or a MOV file, that is expected: re-mux it to MKV with MKVToolNix or FFmpeg, then load the MKV here.

Frequently Asked Questions

What types of subtitles can be extracted?

This tool extracts text subtitle tracks stored inside MKV and WebM containers, including SRT, WebVTT and ASS/SSA tracks. Burned-in subtitles, which are rendered into the video frames during encoding, cannot be extracted by any tool. Image-based tracks such as PGS and VobSub are pictures rather than text and are not read here.

What output formats can I save?

You can save the selected track as SRT (SubRip) or as WebVTT. SRT is the format almost every desktop and TV player accepts; WebVTT is what the HTML video element and most web players expect. The cue text and the timings are the same in both.

Can I extract subtitles in multiple languages?

Yes. Every subtitle track found in the container is listed, so a file carrying English, Spanish and a forced track shows all three. Pick one from the dropdown, check the preview and save it, then choose another track and save that one too.

Is my video uploaded anywhere?

No, not the video. The file is parsed in your browser and the tool code sends no part of it to a server. The page itself loads analytics and ad scripts, as most websites do, so a network monitor shows requests from those. They are separate from the tool code.

Why does it say 'No subtitles found'?

Three things cause it. The file is an MP4 or a MOV, whose subtitle tracks this tool does not read; the container genuinely has no subtitle track; or the subtitles are burned into the picture, which no tool can recover as text. For an MP4 or a MOV, re-mux it to MKV with MKVToolNix or FFmpeg and load the MKV here.

What is the difference between soft subtitles and hardcoded subtitles?

Soft subtitles are stored as a separate data track inside the video container and can be turned on or off by the viewer. Hardcoded subtitles are permanently rendered into the video frames during encoding and cannot be separated from the image.

Is there a file size limit for videos?

Yes. The page accepts files up to 500 MB and refuses anything larger before parsing starts. The video is read in your browser, so within that cap the practical limit is your device's available memory rather than a server quota.

Can I extract subtitles from YouTube or streaming videos?

No. This tool reads local files on your device, not URLs. For YouTube, use its own transcript feature. For anything else, download the video together with its subtitle tracks, and load the MKV here if the tracks are inside the container.

Can I save the subtitles as VTT or ASS?

VTT yes, ASS no. Any extracted track can be saved as SRT or as WebVTT. ASS and SSA tracks can be read out of the container, but their styling is dropped when the cues are written as SRT or VTT. If the styling has to survive, pull the script out with MKVToolNix instead.

Can I use this tool on my phone or tablet?

Yes, the tool works in any modern mobile browser. However, processing large video files on mobile devices may be slower due to limited memory and processing power compared to a desktop computer.
