Why Online Ebook Metadata Editor?

Organize your digital book collection by editing EPUB metadata, author credits, and publication details locally in your browser.

Private In-Browser Sanitization

Unlike typical online web converters that require sending your private documents to third-party cloud servers, TagEditor cleans and modifies your files locally in your web browser memory. Your files are never uploaded, logged, or retained anywhere.

No Software Installation Required

Works directly on Windows, macOS, Linux, iPhone, iPad, and Android without needing command-line tools like exiftool, ffmpeg, or desktop software installs.

Preserves 100% Quality

Only the metadata headers are stripped or altered. The actual image pixels, audio streams, video codecs, and document text are preserved intact without lossy compression.
