Why other tools watermark subtitle exports
Veed, Kapwing and Clideo are venture-funded SaaS products. Their business model forces a paywall: free users get watermarked exports so paid users have a reason to upgrade. The watermark isn't a technical limitation — it's a marketing tactic.
Why BurnSub doesn't need a watermark
BurnSub runs entirely in your browser. There's no server processing your video, no GPU costs to recoup, no SaaS subscription to fund. The tool is built by a solo developer and pays for itself through optional Google AdSense, not paywalls.
Your video stays on your device. The output is exactly the file you'd get from a $24/month plan — minus the watermark, minus the signup, minus the wait.
How to remove a watermark from a Veed or Kapwing video
You can't, legally — those tools embed the watermark during export. The only clean path is to re-burn captions on your original video file using a tool that doesn't watermark in the first place. BurnSub does exactly that, free, in your browser.
What about file size or length?
BurnSub has no upload, so there's no upload-size limit. Videos are processed locally with WebCodecs — your hardware is the only cap. Most modern laptops handle 4K input fine. Phones cap out around 1080p.
Is BurnSub really free forever?
Yes. The tool is funded by ads, not subscriptions. There's no Pro tier to upgrade to — the watermark-free output, 4K support, all 200+ styles and the full Whisper-Turbo auto-caption are available to everyone, on the same URL, without an account.
