SRT
Free. No account. No watermark.
How it works
Drop, style, export.
Drop your video and SRT
The video and the subtitles stay on your device. Both are read locally, into the browser's private storage. Nothing uploads.
Style the captions
Pick a template, tune sizes, colours, and animations. The preview updates in place. Word timings come straight from the SRT cues.
Export a subtitled video
The captions are burned into the pixels. The exported MP4 plays with subtitles baked in on any player, no separate track to lose.
Beyond SRT
Word-level precision. AI on top.
SRT files carry timings per line. That works for readable captions, but the word-by-word styles that go viral on TikTok, Reels, and Shorts drift when the timing source is per-line. tscaps cloud transcribes with AI at the word level and layers editing intelligence on top of it.
Word-level timings
Every word timed precisely, so word-by-word caption templates fire on the exact syllable instead of drifting inside the cue.
Auto-picked emojis
Emojis chosen per phrase from the transcript context — no manual pass, no template that reads flat.
Bad takes removed
Filler words, stumbles, and repeated takes flagged and cut so the final video reads clean without editing frame by frame.
Hooks + tagged words
The opening hook is detected and styled distinctly. Semantic tags mark the important words so templates emphasise them naturally.
FAQ
Frequently asked questions.
What is an SRT file?
SRT (SubRip) is a plain-text subtitle format. Each cue has a start time, an end time, and a line of text. Most transcription and captioning tools can export SRT — Whisper, YouTube auto-captions, Aegisub, and many others.
How do I add an SRT file to a video?
Drop the video in the first slot and the SRT in the second, then press Start. The editor opens with the cues loaded as captions you can restyle or retime. Export when it looks right — the result is a video with the subtitles permanently added.
Does the tool upload my video or my SRT?
No. Both files stay on your device. The tool opens them locally, the browser renders the captions on top of the video, and the export composites frames in-page. Nothing is sent to a server.
What video formats work?
MP4, WebM, and MOV. Support depends on your browser's built-in codecs — most modern browsers handle MP4 (H.264) out of the box. Chrome, Edge, and Firefox on desktop are the smoothest experience today.
What does it mean to burn the subtitles?
The captions are baked into the pixels of the exported video. There is no separate text track that can be toggled off or lost. The output plays the same way on TikTok, Reels, Shorts, or any other player.
Can I convert an SRT to MP4?
That is what this tool does. An SRT alone carries no images, so the conversion always pairs the subtitle file with a video: the tool merges your SRT with your MP4, WebM, or MOV and exports a video with the subtitles rendered into every frame.
Can I edit the captions before burning?
Yes. The editor loads the SRT cues as segments you can rewrite, retime, and style. You can also change wording, adjust timings per cue, and pick a caption template for each part of the video.
Does the exported video have a watermark?
No. Everything runs on your device, so there is no watermark on the output.
Can I use a VTT file instead of SRT?
Yes — there is a companion tool that accepts WebVTT files directly. If you have a VTT file, open the VTT variant of this tool; if you have both formats, either one works.
How long can my video be?
There is no fixed cap. Longer videos take longer to export because every frame is rendered in the browser; for practical results, most visitors work with clips under fifteen minutes.
