Open common ebook and document formats privately in your browser without sending the file to an application server.

DRM-protected books

PDF

PDF files open through your browser's built-in local PDF viewer. Available controls can vary by browser.

TXT and Markdown

Plain-text and Markdown files open in a focused reflowable reader with theme and text-size controls.

FB2
