# Caption Maker > A caption maker turns the speech in a video into on-screen captions. Some are phone apps; Kenerate's runs in the browser, so there's nothing to install. Upload a clip up to 4 minutes, pick one of 10 caption styles and a position, and download one MP4 with the captions burned in, ready for any platform.

Captions, the app now developed by Mirage, runs on iOS, Android and the web and adds editing, dubbing and script tools on top [2]. Social apps have their own: Instagram's Captions sticker transcribes Reels in the mobile app [3]. ### When a browser beats an app A browser caption maker skips the install, which matters more often than you'd think. - Work laptops where you can't install software. - Clips edited on a computer rather than a phone. - Several people sharing one account on different devices. - Phones that are short on storage space. - One-off captioning jobs that don't justify a subscription. ### When an app is the better choice If you want to fix individual words, re-time lines, add emojis or design your own caption template, a full captions app or editor does more [1]. Kenerate's caption maker is deliberately narrower: it takes a finished clip and gives back a captioned one in a few minutes, with 10 ready-made looks instead of a design canvas. ### Captions that survive reposting Because the captions are part of the image, they travel with the file: reposted, forwarded or embedded, the video still shows them. That's the main advantage over captions that live inside one app's player. The cost is that they can't be removed later, so keep your uncaptioned original as well.

A: Yes. Kenerate's caption maker runs in the browser on a computer or a phone, so there is nothing to download: sign in, upload the clip and download it captioned. Phone apps such as Captions, or Instagram's Captions sticker, need their app installed. A browser tool is also handy on shared or work computers where you can't install software. Q: Do I need a captions app or a website? A: It depends on where you edit. If you shoot and post from your phone and want to change words by hand, a captions app with an editor fits. If your clips are already finished and you just want styled captions burned in, a browser caption maker is quicker: Kenerate takes the file, captions it and returns one MP4. Q: Can I use the caption maker on my phone? A: Yes, in the phone's browser. Open Kenerate, sign in, upload a clip from your camera roll and pick a style; the result downloads as an MP4 you can post straight from the phone. Keep clips under 4 minutes and 100 MB. For the clearest text on a small screen, choose 1080p HD and a Mid or Max shadow. Q: Can the caption maker add emojis or my brand font? A: No. It offers 10 fixed caption styles, from Simple to Vegas, with position and text-shadow settings, but no custom fonts, colours, emojis or logos. If your brand needs an exact font, caption the video in an editor with brand kits. For most social posts, using one built-in style across a series reads as a consistent look too. Q: Does the caption maker add a watermark? A: No. The captioned MP4 has no watermark, and no subscription is required: you pay per clip with credits, priced by length in tiers up to 4 minutes, and new accounts get starter credits to try it. If a run fails, the credits are refunded automatically, so a bad upload doesn't cost you anything. Q: Which languages can the caption maker caption? A: It captions speech in English (US), English (India), Spanish, French, German, Japanese, Chinese, Italian, Portuguese and Russian, with Auto-detect as the default. The captions match the spoken language and there's no translation step, so a French speaker gets French captions. Pin the language by hand when a clip mixes languages or the accent is strong. ## Related pages - Add subtitles to video: https://kenerateai.com/add-subtitles-to-video - AI caption generator: https://kenerateai.com/ai-caption-generator - Add captions to video: https://kenerateai.com/add-captions-to-video - Instagram Reels captions: https://kenerateai.com/reels-captions - How to add subtitles to video: https://kenerateai.com/how-to-add-subtitles-to-video ## Sources - Kenerate Auto Subtitles (tool): https://kenerateai.com/app/tool/subtitles - Captions — AI video caption generator, checked 3 October 2026: https://captions.ai/features/add-captions-to-videos - Captions (app) — Wikipedia, checked 3 October 2026: https://en.wikipedia.org/wiki/Captions_(app) - Kapwing — How to add auto-captions to Instagram Reels (2 May 2024), checked 3 October 2026: https://www.kapwing.com/resources/instagram-reels-captions/
