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.
How many PDFs can I merge?
BookForge sets no fixed limit. In practice the number is limited by your device memory and performance.
Can I change the file order?
Yes. Move each file up or down before merging.
