Does this upload my data?
No. This tool runs in a browser worker. Input is not stored or sent to a server.
Does Base64 change a file format?
No. Encoding and decoding preserve bytes. A format-specific tool checks the signature, but does not transcode or guarantee that a file is intact. Some media may not play in your browser; the download still preserves the bytes. SVG and HTML are never rendered here.
