A .mobi or .azw3 from an old download usually means a detour: convert it first, or hand it to a site that wants the file uploaded. This reader opens it as it is, in a browser tab, and the file stays on your computer.
No conversion, no account, no upload. This is a reader, not a converter: nothing comes back out as a new file.
Go to the reader in any modern browser. There is nothing to sign up for and nothing to install.
Drag the .mobi or .azw3 anywhere onto the page, or click Open book… and pick it. Several files at once is fine.
Chapters, search, highlights, bookmarks and the dictionary all work the same, and the book joins your library in this browser.
Whatever the format, the reading side is the same: page numbers that hold their value when you change the font size, time left in the chapter, search across the whole book with every match grouped by chapter, four highlight colours with notes, bookmarks, and a dictionary that looks a selected word up in Wiktionary.
No. This site is static files with no server behind it. The book is read in the browser and kept in the browser's own storage, along with your place and highlights.
Try it. A protected file fails to open and the reader says so; an unprotected one opens in a second or two.
Yes, the Chrome extension and the web reader are the same reader in different shells (the Edge and Firefox versions catch up as their stores approve each update). The extension adds an offline library and can open .epub links from the web directly.
Yes. Pro is a one-time purchase for unlimited read aloud, highlight export to Markdown and reading statistics.
