Always keep the original
A small habit that saves headaches later. This guide shows the safe Add Subtitles to Video workflow that always preserves the source file before any edit.
If you've ended up here, you have a video and a specific job: preserving the original. 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 — Runs entirely on your device using open web standards.
Why preserving the original needs different settings
A video for preserving the original 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.

Recommended settings for preserving the original
Launch the tool
Everything happens locally in your browser — your file never leaves your device.
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
Should I rename the result?
Often yes. Recruiters and portals often pre-filter by filename patterns; a clean, predictable name (e.g. "FirstName_LastName_Resume.pdf") is worth the 10 seconds.
Does compressing a video make it look unprofessional for preserving the original?
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.
Will Add Subtitles to Video work for a batch of videos?
Yes — drop multiple files at once. All of them get the same preserving the original settings applied, then downloaded as a folder.
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.
