If you need to edit documents in different formats using only the usual browser like Chrome, Firefox or Safari, without installing any editing software like Microsoft Office or OpenOffice, then MOBI Editor App is exactly what you need!

The Editor App is free and requires no registration. To use it just drag and drop a file to upload, edit it in-browser, and download the final version in your chosen format either the original or as a PDF. The online MOBI Editor is very easy to use. It runs directly in your web browser, so you don't need to download any plugins or extra software. Whether you’re on a computer with Windows or macOS, or on a phone or tablet like an iPhone or Android device, the app will work perfectly.

WYSIWYG-editor with its toolbar adapts to the specific format of an uploaded document, enabling those features and possibilities, which are actual for only this format and disabling those, which are not related. In particular, for E-Books, plain text documents and HTML/XML all toolbar features will be unlocked (because you can open TXT document, for example, and then decide to save it as DOCX), but the content will be represented in continuous and uninterruptible form.

Mobipocket eBook

The MOBI file format is one of the most widely used ebook file formats. The format is an enhancement to the old OEB (Open Ebook Format) format and was used as the proprietary format for Mobipocket Reader. Like EPUB, it is supported by almost all modern e-readers specifically by mobile devices with low bandwidth. The format can be converted to several other formats such as PDF, EPUB, and several other formats using publicly available software applications such as the Kindle app.

FAQ

Questions & Answers

How can I edit a MOBI file using MOBI Editor?

First of all, you need to select and add this file for editing by two ways: drag and drop your file to the white area with the label ”Click or drop your file here” or click on this area and then select the desired file using file explorer. Once a file is added, the green progress bar will begin to grow, and when completed, the MOBI Editor will be opened with file content inside it.
The Editor was opened after file uploading, but there is a “Please wait, while document is loading” message and no any document content. Will it appear and how long does it take?

The document loading time depends on three factors: document size, the complexity of document content and aspects of the document format. For example, plain text files (TXT) are much easier to open and display than XLS spreadsheets, and it may be faster to open an eBook with a huge 1000 page novel inside rather than a complex 10-slide PPTX presentation with tons of animations, comments and images.
How can I edit the content of a document when it is opened in the Editor?

In short: like in any other WYSIWYG-editor. There is a toolbar with three groups of tools: File, Format, and Insert. First group contains buttons for saving and downloading the document, second is responsible for formatting existing content, while third — for inserting the new entities inside content like images, tables, lists and so on. There also are two emerging groups of buttons on the toolbar — Table and List. They appear when you point at a table or a list respectively and contain tools for working with them like adding or removing table rows and columns, list indentation and so on.
Does MOBI Editor require an internet connection when a document is loaded and opened?

Yes, the MOBI Editor is a client-server tool where WYSIWYG-editor is only a facade for a server-based software. If an internet connection is lost during document editing, you will not be able to save and download the edited document.
What about privacy, is it safe to use the MOBI Editor?

Yes, it is. Editor usage scenario implies that you select and open a document, edit it and then save and download the edited version, and that’s all. The unique URL is generated after you’ve opened the file, but this URL is known only for you and no one else. Finally, the uploaded file will be automatically deleted from our servers after 24 hours after uploading and this URL will become inactive.
Can I edit a document on Linux, Mac OS or Android?

It can be anything that has a modern browser and an internet, no matter what device it is, which operating system is there, and what the browser is. PC or smartphone, Windows or Mac OS, Android or iOS, Chrome or Firefox, — all of them are supported.
