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.

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 have a PDF consisting of images — then both us and Calibre developers do not recommend converting it to any ebook format.

Great ebook converter. I wish I can buy it instead of being forced into unacceptable monthly subscription.

★★★★★Just “nowhere” me· Jun 6, 2025
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
★☆☆☆☆Joyce Chow· Apr 22, 2025
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.
★☆☆☆☆Sam Rome· Dec 24, 2025
This is stupid, can't convert PDF to epud, or doc, can't convert epud to doc or PDF. What's the purpose
★☆☆☆☆Timothy Wagenknecht· Jan 25, 2026
Only able to convert 20mb files. Waste of time, who has cbr files that are less than 20mb?
★☆☆☆☆spamolot -· Nov 25, 2025
Didn't work at all. "Connection to the server is broken." I was also looking for an offline converter as online ones aren't working for my PDF due to size.
