Frequently Asked Questions

Q: Is my video uploaded to any server?

No. All processing happens entirely in your browser using Canvas and MediaRecorder APIs. Your video never leaves your device.

Q: What video formats are supported?

You can input MP4, WebM, and MOV files. The exported watermarked video is in WebM format.

Q: Why is the output in WebM format?

The browser's MediaRecorder API outputs WebM. WebM is widely supported and can be converted to MP4 using a free video converter if needed.

Q: Can I add an image watermark instead of text?

Currently the tool supports text watermarks only.

Q: Is there a file size limit?

There is no hard limit, but very large videos may require more browser memory and time to process.
