Free video and subtitle tools
Small tools for the jobs around a short video, free with no sign-up. Each one runs in your browser: your file or text is opened on your device and never sent anywhere.
Safe zone checker
Drop a video or picture and see what the Instagram Reels, TikTok and YouTube Shorts buttons, name and caption cover. Save a transparent 1080 x 1920 template for each app.
Text to SRT converter
Paste text or drop a .txt file and download an SRT subtitle file, split at sentences and phrases and timed by reading speed or a total length.
And the main tool: captions burned in
Burncaps itself burns animated word-by-word captions into a talking video, or cuts it to its best 30 or 60 seconds, in your browser. It listens to the video, times every word to the voice, and lets you correct any word before you export. SRT, VTT, ASS and text files are free without limit for recordings up to ten minutes.
Free to use: two videos every 30 days with no mark, or $49 once for unlimited videos.
