← All formats

Step 1. Choose the file you want to convert.

Converting from PDF

PDF input is parsed page by page with pdf.js. Text, headings, and tables are extracted when the file contains a real text layer — image-only scans without OCR are not supported.

Output as EPUB

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.

FAQ

PDF to EPUB: why is scanned text missing?

When converting PDF to EPUB, only a selectable text layer is extracted — not images of pages. Scanned documents without OCR often produce empty or very short EPUB output. Use a PDF where you can select text with the cursor. OCR support is on our roadmap.

Are my files sent to a server?

No. Conversion runs entirely in your browser; files never leave your device.

What formats are supported?

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.

Why does the result differ from the original?

The converter works with content (text, tables), not layout. Styles, columns, and complex formatting may be lost.

Is there a file size limit?

Limited by browser memory and OPFS. Large files work better in Chrome and Edge; on mobile devices, use smaller files when possible.

Which browsers are supported?

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.

Can I convert multiple files at once?

Yes. Select several files, choose one output format, and download all results in a single ZIP after conversion.
