Frequently Asked Questions

Yes, completely free. Convert PDF to YAML with no cost, no signup, and no usage limits.

The conversion extracts text content, document metadata, heading structure, and basic formatting information organized into hierarchical YAML keys. Complex visual layouts may be simplified.

No. YAML is a text-based data format. Images are not included, but their placement and alt-text (if available) may be referenced in the structure.

Text-heavy PDFs with clear heading structure convert well. Complex multi-column layouts, heavily formatted documents, or image-heavy PDFs may produce simplified output that requires review.

No. The PDF must not be password-protected or encrypted. Remove password protection before uploading for conversion.

No. Files are automatically deleted immediately after conversion. Nothing is stored or retained on our servers.

The conversion uses LibreOffice headless on secure servers to parse PDF structure and extract content into structured YAML format.

Scanned PDFs contain images, not extractable text. The conversion will produce minimal YAML output since there's no machine-readable text to extract.

No. The conversion follows a standard structure extraction process. For custom YAML formats, you can edit the output file after download.

The YAML typically includes document title, author (if available), creation date, page count, and extracted content organized by document structure.
