ODT input

Is there a limit on the book size?

Yes, the maximum size of the ODT input file is 3 MB

Can all ODT files be converted?

No, some ODT files with complex styles and formatting will fail because the XHTML output filter is not able to handle them.

If exporting as XHTML from fails, it is a good indication that the file is too complex.

Are the input files stored?

Input files are only stored temporarily during the conversion process, not permanently. They are never distributed or used for any other purpose.

Conversion process

How long does it take to convert?

Several seconds to several minutes, depending on the complexity of the book

Can I convert several books at once?

Not at the moment

Can you clean up my book?

No, the conversion process is entirely automated, and it does not make any changes to the original ODT file.

What features are supported by the converter?

You can find them in the Features section

What are the customization options?

You can enter book metadata such as title and creator (and overwrite the original metadata from ODT).

What is the ePub sample file?

It is a full version of you ePub output, including a banner after each page-break

ePub output

What metadata is included in the ePub file?

Dublin Core 1.1 elements title, language, identifier, creator, and publisher are extracted from the original ODT, if they are present there.

You can overwrite ODT values with your own in the Options step.

The terms title, language, and identifier are mandatory according to the ePub specification, the rest is optional. If you do not provide them, the result file will be invalid (but readable).

How is XHTML content packaged?

It is split into several files to make it load faster and try to keep the filesize under the 300 KB limit.

Currently the splitting is done on elements which ODT style includes a page-break before them.

The converter however does not ensure that all files fall under this limit. You have to make sure your input styles (usually headings) contain page-breaks to keep the chapters reasonably sized.

What is the 300 KB per file limit?

Some hardware readers (e.g. some Sony Reader versions) have memory limitations, which makes them unable to load an ePub package that contains files larger than 300 KB

What kinds of length units are used?

It is recommended to use relative units (em and %) in ePub to make the content scale gracefully when the font size is changed.

So far ODT2ePub only recalculates font-size property from absolute to relative values, other absolute values remain unchanged. You might want to use relative values where possible in the original ODT.

Can I add DRM to the ePub file?

Not with ODT2ePub. DRM might be the very reason why the e-book market has not taken off yet, but if you still think you need it, 3rd party software like Adobe Digital Editions might be able to do that.

What if I want to make changes in my ePub file?

Make necessary changes in the input ODT and convert again, or use editing software that supports ePub format (such as Sigil).

How is the output quality ensured?

In the premium version, the ePub output is validated according to the standard specification using the EpubCheck tool. The validation output is provided.


Do you support Microsoft Word (DOC) format as well?

DOC can also be easily exported as OpenDocument (ODT).
