PDF preserves a fixed page layout across devices and operating systems.
EPUB packages reflowable or fixed-layout publication content for ebook readers.
Selectable text from up to 250 chosen pages becomes a reflowable EPUB with one navigation chapter per source page.
The title and optional author are stored as ebook metadata. Scanned pages need OCR first, and source images, forms, links, annotations, columns, tables, fonts, and fixed page layout are not reproduced.
Choose an optional inclusive first and last page, select the text flow, and set the ebook title plus an optional author. Every selected source page becomes a reflowable navigation chapter.
One PDF is processed per request. The input limit is 50 MB.
The web application validates the file before forwarding it to a private worker. The worker validates the signature again, processes the file inside a unique temporary directory, validates the output, and removes the job directory in a guaranteed cleanup path. Files are not written to the database or retained for analytics.
When you import from a URL, the application fetches only a validated public HTTP or HTTPS address, checks the downloaded file in memory, and applies the same worker cleanup rules. The URL, filename, and file contents are not sent to analytics.
