E-book library
Clean metadata for books and documents
Better display in your library
E-readers and document applications use embedded metadata for titles, authors and sorting. BookForge writes the new values into a copy of your file.
- Title and author
- Language
- Subject and keywords
- Cover image for EPUB
Differences between PDF and EPUB
Metadata fields are updated in both formats. New cover images are currently embedded only in EPUB files; existing PDF page layouts stay unchanged.
Frequently asked
FAQ
Are my files uploaded?
No. Selected EPUB and PDF files are processed locally in your browser and are not sent to BookForge for conversion.
Do I need an account?
No. BookForge works without an account, email address or registration.
Are there watermarks or usage limits?
No. BookForge adds no watermarks and does not limit the number of local conversions.
Can I replace a PDF cover?
No. Cover images are currently embedded only in EPUB files. PDF metadata can still be edited.
Will my original file remain intact?
Yes. BookForge downloads a new file containing the updated metadata.
