About ODG Files

ODG (OpenDocument Graphics) is the standard format used by LibreOffice Draw and Apache OpenOffice for vector drawings. Like all OpenDocument formats, an ODG file is actually a ZIP archive containing XML for the drawing data, an embedded thumbnail PNG, and any images placed into the drawing.

What this tool extracts

Thumbnail PNG — Every ODG saved by LibreOffice/OpenOffice includes a Thumbnails/thumbnail.png preview image generated at save time
Embedded images — Any raster images (PNG, JPG, etc.) imported into the drawing are stored in the Pictures/ folder inside the archive
Document metadata — Title, author, creation date, and description from the ODG's metadata

Frequently Asked Questions

Does this tool upload my files anywhere?

No. Everything runs entirely in your browser using the JavaScript File API and JSZip. Your ODG files never leave your device.

Why is the thumbnail small?

The thumbnail is generated by LibreOffice at save time — typically at 128×128 or 256×256 pixels. It's designed as a preview, not a full-resolution export. For high-resolution PNG output, open the file in LibreOffice Draw and export via File → Export as Image.

Can I convert ODT and ODP files too?

Yes — the same structure applies to all OpenDocument formats. ODT (text), ODP (presentation), and ODS (spreadsheet) files all contain a thumbnail and any embedded pictures that this tool can extract.

What if no images are found?

Some ODG files contain only vector shapes with no embedded raster images, and were saved without generating a thumbnail (e.g. exported programmatically). In that case the tool will report what it found and offer the document metadata.
