How the Video Burn Caption Tool Works
Permanently burn captions or subtitles into your video so they are always visible on any device or platform, even when closed captions are not supported.
1. Upload your video
Drag and drop a video file (MP4, WebM, AVI, MOV, MKV) into the upload area or click to browse your device. The tool shows basic duration, size, and format information.
2. Add or upload captions
Type a single caption with custom timing or upload an SRT/VTT subtitle file. You can preview, edit, and fine-tune each cue before burning it into the video.
3. Style and burn to video
Choose caption position, font size, colors, background style, and outline, then start processing. When the render is complete, preview the result and download the new video with permanent captions.
Key Features & Benefits
Create hardcoded subtitles for social media, training materials, and accessibility-friendly videos with full control over style and placement.
Permanent burned-in captions
Captions become part of the video itself, ensuring they show up on every platform, player, and device without relying on external subtitle support.
Support for SRT & VTT files
Upload existing subtitle files, automatically parse cues, and edit timing or text in a simple in-browser editor before exporting the final video.
Flexible styling controls
Adjust font size, color, background style, and outline thickness so your captions stay readable on any footage, from dark scenes to bright backgrounds.
Multiple position options
Place captions at the top, bottom, center, or corners of the video to avoid covering important visuals or on-screen elements.
Improve accessibility & engagement
Make your videos more accessible for deaf or hard-of-hearing viewers and increase engagement on mute-first platforms like social media feeds.
Free to use, no watermark
Process as many videos as you need without hidden fees or intrusive watermarks being added to your content.
Frequently Asked Questions
Answers to common questions about burning captions directly into your videos.
Burning captions means the text is rendered directly onto each video frame, creating a new file where subtitles are permanently visible and cannot be turned off.
The burning process uses a WebAssembly-powered media engine in your browser. Videos are processed locally and are not permanently stored on our servers.
You can upload standard .SRT and .VTT subtitle files. The tool parses cues into an editable list so you can adjust timing or text before exporting the final video.
The video is re-encoded to apply the caption overlay. There may be a small change in file size or quality, but we aim to keep the output close to the original while preserving smooth playback.
Processing time depends on video length, resolution, and your devices performance. Short clips usually finish in a few minutes; longer HD files may take longer to render.
The tool may work on some modern mobile browsers, but video processing is resource intensive. For best results and faster rendering, we recommend using a desktop or laptop computer.
