Does the file get uploaded to a server?

No. SubRip → WebVTT runs right in your browser and the file never leaves your device. It only goes to a server if the browser cannot cope — and then we delete it within a couple of hours.

Will caption styling survive?

Yes, WebVTT keeps position and styling — captions stay where they were.

Can I get the original quality back afterwards?

Yes, WebVTT supports lossless compression, so you can go back to the original.

How many files, and how large?

Up to 20 files at a time, 5 MB each. No sign-up, no watermarks.

SubRip

Good at

Every player and every platform understands it, without exception
Plain text inside: opens in a text editor and is edited by hand
The format has not changed in twenty years, so files do not age

Awkward about

No position, no colour: the caption sits wherever the player puts it
Browsers cannot read it directly — it has to become WebVTT
The encoding has to be guessed: the file declares none

Use it when

Subtitles are going to YouTube, a TV set or a desktop player
The file will be edited by hand
You want the most compatible option there is

WebVTT

Good at

The browser’s own format: attached to a video in one line
Supports position, alignment and styling — captions can move off a face
Always UTF-8, so non-Latin text never turns into rubbish

Awkward about

Household players and TVs usually expect SubRip
Some platforms reject it on upload
Not every player that reads the format honours its styling

Use it when

The video plays on a site through a video tag
Captions need to move off faces or name the speakers
Subtitles are served together with the page
