Why convert ODT to EPUB
ODT and EPUB look similar at a glance, but they behave very differently once you try to edit, share, or publish them. Choosing the right format saves hours of cleanup later — that is what this conversion is for.
Most people switch from ODT to EPUB because the destination app, platform, or teammate expects EPUB. Email systems, content platforms, and collaboration tools all have a preferred shape, and converting up front avoids surprises.
EPUB also tends to handle a specific workflow better than ODT: editing, archiving, web publishing, or print. The conversion makes the file fit the next step instead of fighting it.
Common use cases
- Edit a ODT that arrived as read-only by converting it to EPUB first.
- Repurpose long-form ODT content into a EPUB you can paste into another tool.
- Share a ODT with a teammate who only opens EPUB files.
- Archive a ODT in a more portable EPUB format for long-term storage.
- Get a EPUB version for a CMS, e-reader, or publishing pipeline that does not accept ODT.
Tips for best results
- Tidy up your ODT before converting: remove leftover comments, accept tracked changes, and clean up extra page breaks.
- Custom fonts in your ODT may be substituted in EPUB if the target format cannot embed them. Stick to common fonts for best fidelity.
- Keep your file under 50 MB. Larger files are available on Pro — leave your email on the pricing page for early access.
- Conversion is one-way — your original ODT is never modified. Download the new EPUB and keep both if you need to.

Frequently asked questions
Is the ODT to EPUB converter free?+
Yes. Guests get 5 conversions per day for free. Sign in with Google to bump that to 10 per day plus batch ZIP downloads. No credit card and no trial — the free tier stays free.
Is it safe to upload my ODT file?+
Yes. Files are uploaded over HTTPS, processed in isolated jobs, and automatically deleted from our servers within one hour. We do not share files with third parties and do not train models on your content.
Do my files get deleted? When?+
Both your original ODT upload and the converted EPUB output are deleted within one hour. You can delete files manually from your account page right after download if you sign in.
Do I need to sign up or install anything?+
No. The converter runs in your browser; conversion happens in the cloud. You do not need to install software, register, or give us an email. Google sign-in is optional and only unlocks the higher daily limit.
What is the maximum ODT file size?+
50 MB per file on the free tier. Pro will lift this to 500 MB per file and 2 GB per batch — leave your email on the pricing page for early access.
Does it work on Mac, Windows, iPhone, and Android?+

Will my ODT file look the same after converting to EPUB?+
We preserve as much as the target format supports — fonts, layout, colors, and metadata where possible. Some properties (like editable text in an image format, or transparency in a non-transparent format) cannot survive the conversion and will be flattened or dropped.
Can I convert multiple ODT files at once?+
Yes — sign in with Google and use the batch uploader. We zip all converted EPUB files into a single download. Guests can convert one file at a time.
