Is Add Subtitles to Video safe for sensitive videos?
The honest answer on what happens to your video inside Add Subtitles to Video — and why "no upload, no account" matters for sensitive files.
If you've ended up here, you have a video and a specific job: sensitive content. The defaults most software ships with aren't tuned for that — they're tuned for "archive everything at maximum quality," which is the opposite of what you need now.
Launch the tool: Add Subtitles to Video — Everything happens locally in your browser — your file never leaves your device.
Why sensitive content needs different settings
A video for sensitive content optimises for things the original video doesn't care about: small enough to upload quickly, compatible with whatever software the recipient is using, and free of embedded metadata that could leak personal information. The defaults give you the opposite — large, high-quality, metadata-rich. Useful for some jobs, wrong for this one.

What to verify before sending
Quick check-list once Add Subtitles to Video finishes:
- Open the result. Make sure it looks right at the size the recipient will actually see it.
- Check the file size. Match it against the limit you're targeting.
- Confirm the file extension. Sometimes you need to rename — for example, a recipient who expects
.jpgwon't necessarily accept.jpeg. - Send a test to yourself first. Open the test on the same device the recipient will use, if you can.
Frequently asked questions
Does compressing a video make it look unprofessional for sensitive content?
Not when done right. Sensible compression at the "balanced" preset produces output indistinguishable from the original to the human eye, even at half the size.
Can I undo the compression later?
No — compression is one-way. Always keep the original video archived somewhere, and treat the compressed version as a send-only copy.
Is Add Subtitles to Video safe for sensitive videos like a resume or visa documents?
Yes — every step happens locally in your browser. The video never leaves your device because there is no server in the loop.
What if the recipient asks for the original?
Keep the original. Add Subtitles to Video produces a copy; the source file you dragged in is never modified.
