Place the watermark in a corner for minimal disruption — bottom-right is the most common professional position.
Use a moderate font size that is readable but does not dominate the video frame.
Keep the original unwatermarked video as a backup — the watermark cannot be removed after processing.
For maximum protection, place the watermark in the center — this makes it harder to crop out.
FyleTools uses FFmpeg compiled to WebAssembly to overlay text on each video frame using the drawtext filter. The text is rendered at your specified position, font size, and opacity, then the video is re-encoded as MP4. All processing happens locally in your browser.
