Convert ODT (.odt) to EPUB (.epub) in your browser — no upload, no account. Output: reflowable .epub ebook — readable on phones, tablets, and e-readers.
← All formatsStep 1. Choose the file you want to convert.
ODT files (ZIP + content.xml) are streamed and parsed locally. Writer styles and frames may flatten to paragraphs and tables in the output.
Chapters are packaged into EPUB3 with a table of contents. Images from the source are not embedded unless already present as content.
All conversion runs locally in your browser via Web Workers. Your files are not sent to any server, which makes ydoconv suitable for confidential documents, drafts, and large batches.
No. Conversion runs entirely in your browser; files never leave your device.
Supported formats: TXT, PDF, DOCX, RTF, ODT, CSV, JSON, FB2, EPUB, XLSX, HTML, MD. Upload a file above — the converter detects the source format and shows compatible targets.
The converter works with content (text, tables), not layout. Styles, columns, and complex formatting may be lost.
There is no OCR. You need a PDF with a selectable text layer. OCR support is on our roadmap.
Limited by browser memory and OPFS. Large files work better in Chrome and Edge; on mobile devices, use smaller files when possible.
Chrome, Edge, Firefox, or Safari 16+. Web Workers are required; OPFS is needed for large DOCX, EPUB, and XLSX files. Internet Explorer and outdated browsers are not supported.
Yes. Select several files, choose one output format, and download all results in a single ZIP after conversion.
