A FEW THINGS TO KNOW
Good questions.
Clear answers.
Less guesswork. More creating.
Can I create subs for TikTok free online?+
Yes. Subtrims is a free online subtitle generator for English TikTok videos, Instagram Reels and YouTube Shorts. No account or credit card is required. Upload a clip up to 5 minutes and 100 MB, choose 2 to 5 words per caption, then edit and download SRT or TXT. Transcription runs locally in your browser; the first run downloads the AI model.
Which languages are supported?+
Subtrims transcribes English speech only. Other spoken languages and translation are not supported yet.
How do I create subtitles for TikTok, Reels or YouTube Shorts?+
Upload your video or audio, generate English subtitles on your device, then review the text and timing. Export SRT to a compatible video editor and add the captions to your video before publishing. Subtrims exports subtitle files; it does not render captions into your video.
Can I generate 3-word subtitles?+
Yes. Select 3 words per subtitle to split your transcript into captions of up to three words. Punctuation and pauses can make a caption shorter. You can also choose 2, 4 or 5 words, switch on ALL CAPS, and export SRT or TXT.
What video and audio formats can I upload?+
Try MP4, MOV, WebM, MP3, WAV, M4A, or OGG. Decoding support depends on your browser and the media codec. If a video cannot be read, export its audio as a WAV or MP3 and upload that instead.
How accurate are the subtitles?+
This version uses an English speech-recognition model. Clear speech produces better results; background noise, overlapping speakers, names, and accents can affect accuracy. Review and edit the generated captions before exporting.
Which subtitle formats can I export?+
You can download SRT files with subtitle text and timecodes, or plain-text TXT files with one caption per line and no timecodes. SRT does not reliably carry font styles or keyword colors, so use Pro styled ASS export with a compatible app, or apply styling in your editor. Native styled Premiere Pro and After Effects exports are planned.
What is the maximum video length?+
Free supports clips up to 5 minutes and 100 MB. Pro supports up to 15 minutes and 250 MB per clip, with up to 5 clips processed in sequence. Larger clips need more memory and time. Short clips work best. The first transcription downloads an AI model and may take a few minutes; later runs reuse the cached model.
Are my videos private?+
Media is decoded and transcribed locally on your device. This site does not upload or store your audio or video. The browser downloads model files from Hugging Face and runtime files from jsDelivr. Fonts are served by Google Fonts.
Does it work with Premiere Pro and After Effects?+
Import SRT into Premiere Pro as a caption track. Native styled exports for Premiere Pro and After Effects are planned; After Effects does not have the same native SRT workflow. You can also use SRT with other compatible editors.
Your next great edit
starts with a few words.
