A Safer Way to Handle EPUB Files
No ebook upload
Core EPUB processing runs in the browser. The selected book is kept in memory for the current tab, not sent to a conversion server.
Untrusted content isolation
Publication scripts and external network resources are blocked by default when chapters are previewed.
Non-destructive editing
Editors change the requested package data while preserving unrelated files and metadata wherever possible.
Clear support boundaries
Each tool states what it supports, what it skips, and when a publishing workflow needs additional validation.
Task map

02 / Edit carefully
Correct package metadata or replace a cover without turning the tool into a destructive full-book editor.
03 / Extract content
Export Markdown or UTF-8 text for writing, research, notes, and knowledge-base workflows.

FAQ
EPUB Toolset Questions
Answers about local processing, supported publications, privacy, and current product limits.
Are my EPUB files uploaded?
No. The core tools read and transform the EPUB in your browser. Website hosting and analytics may still receive normal page requests, but the ebook file and its contents are not included in those requests.
Does EPUB Toolset support EPUB 2 and EPUB 3?
The shared parser is designed for common EPUB 2 and EPUB 3 package, spine, NCX, and navigation structures. Individual tool pages list narrower limits where they apply.
Can it open DRM-protected ebooks?
No. EPUB Toolset does not remove or bypass DRM. Use files that are DRM-free and that you have the right to process.
Why are external images or fonts blocked?
A remote resource can reveal your IP address and reading activity. Packaged images and fonts can load locally, while external network resources are blocked by default.
Does it change my original EPUB?
No. Editing tools create a new downloadable EPUB. The original file on your device is not overwritten.
Does it work offline?
File processing is local after the application loads, but the current site does not promise full offline availability because application assets may still need to load from the website.
