Why use Add Subtitles to Video?
Hardcoded Subtitles
Subtitles are burned permanently into the video pixels. They display on any player, device, or platform without separate files.
SRT Import
Upload your SRT subtitle file alongside the video. Timing and text are applied automatically to each frame.
Works Everywhere
Hardcoded captions render on every player and device, so your file looks the same on a phone, a TV, or a social feed.
Social Media Ready
Burned-in subtitles work perfectly on Instagram, TikTok, Twitter/X, and LinkedIn where separate subtitle tracks are ignored.

Frequently asked questions
Hardcoding (or burning) subtitles permanently embeds the text into the video pixels. Unlike soft subtitles, they cannot be turned off but are visible on every player and platform.
Social media platforms like Instagram, TikTok, and Twitter/X often ignore separate subtitle files. Hardcoded subtitles guarantee visibility on every platform.
Yes. Once you add your subtitle file you can choose the font (sans, serif, or monospace), text color, size, and position (bottom, top, or middle) before burning. The defaults are tuned for social video — readable white captions at the bottom — so you can also just upload and go.
We accept .srt and .vtt subtitle files. If you have a different format, our Subtitle Converter tool will convert it for you first.
Yes. Upload MP4, MOV, WebM, AVI, MKV, WMV, or FLV videos. The output is always MP4 for maximum compatibility.
