No - this tool only reads and displays existing metadata; the video file itself is completely unchanged.
Yes. Metadata Viewer is free for normal use with no account required, and ToolBox does not add a watermark to your result.
Most tools in this category run in your browser so the file stays on your device. If a tool needs a temporary server job, files are handled for that job only and are not kept as a lasting archive.
No install needed. Open Metadata Viewer in your browser, add your file or paste your input, then download or copy the result.
Yes on modern mobile browsers. For large files, a desktop browser is usually faster and more reliable.
Try a different quality or format setting, use a smaller input, or open a related tool (for example compress before convert). Keep a copy of the original file before replacing it.
