Description
Convert documents to eBook format (FB2, AZW3, LRF, TCR, SNB, RB, PML, PDB, OEB, MOBI, LIT, EPUB).
Simply select the files which you want to convert and click “Convert”.
After conversion, you can use eBook on your device or share it, for instance, send MOBI to Kindle by email.
We are constantly developing our app and pay attention to your wishes. Therefore, if you have any comments or suggestions — write to us, we will try to implement them (if possible).
For instance, we implemented such functions as: 1. Change the book author and title. 2. Change cover. 3. Send results at once. 4. SD card support.
In the free version, we have limited the number of files that can be used at once and the size of each file. We hope that you will appreciate our work and will be able to support us if you need our application.
You can use our eBook converter for such tasks: * DOC to FB2 converter * EPUB to MOBI converter * EPUB to PDF converter * MOBI to EPUB converter * and more.
Or convert from one format to another: * convert PDF to EPUB * convert PDF to MOBI * convert EPUB to MOBI * convert TXT to EPUB * convert CBR to PDF, CBZ to PDF * and more.
Briefly about conversion: *. Our server is where the conversion takes place. Therefore, your files will be downloaded to the server via the Internet. Accordingly, the application will not work if there is no internet. *. The server will perform the conversion using Calibre. *. The result will be downloaded automatically to your device in the specified folder. *. The original file will be deleted at the end of the conversion, the result will be deleted after 1 hour.
We do not use your files in any way.
The Electronic Book Converter will help you to convert your (DOC, DOCX, PDF) documents or (FB2, EPUB, LIT, etc.) ebooks to formats supported by Kindle (TXT, PDF, AZW, MOBI): EPUB to MOBI, EPUB to PDF, PDF to MOBI, DOC to MOBI, EPUB to AZW.

You can also convert your documents to FB2 format, for example: PDF to FB2, DOCX to FB2, DOC to FB2.
The resulting ebook's file can be larger than the original file, as well as not meet your expectations.
If you are not happy with the conversion result, please contact us. We will try to communicate your feedback to the Calibre developers.
If you have a PDF consisting of images — then both us and Calibre developers do not recommend converting it to any ebook format.

Good for making epub from PDF + works well for making PDF from epub for import into notebook llm. Epubator (not on play store) works too for other way: PDF to epub
★★★★★Josh Hulsey· Jul 20, 2026
One of the best file converters I've tried so far. I used the apps online file converter which opens up your browser and takes you to their website and from their you choose PDF and automatic. Your allowed 10 files at a time to convert so that is awesome! You can also delete the files off their server after completing the conversion. The app itself I believe only allows 5 conversions at a time.

What a great app... when I convert epub to txt, the txt file is broken. I can't believe why converting to txt will fail like this.
★☆☆☆☆Александър Александров· Mar 7, 2026
Absolutely annoying - to process a file you in the free version you need to watch a few minutes of ads.
★☆☆☆☆Petra Rajgelj· Apr 24, 2025
It used to be the best and most useful app I ever used. No more. Doesn't support AZW anymore, to find files you've downloaded months ago is mission impossible. In prior version you could search files by keywords, now it takes you directly to My Drive. Good luck finding anything there. Oh and BTW the first image shown in this intro is a lie. That's how it worked in older version and it was perfect. No more. You can't search files by type (EPUB, MOBI, PDF...)

Trust & Safety: Permissions include network, storage, foreground service, notifications, and billing. Conversions run on a Calibre-based server; the app states that the original file is deleted after conversion and the result is removed after 1 hour, and it claims not to use your files for other purposes.
Each subscription will automatically renew 3 days before the expiration date for
the same time period. Subscriptions can be cancelled at any time before the renewal.
