Supports: ODG
ODG is the OpenDocument Graphics format — the native drawing file of LibreOffice Draw and Apache OpenOffice Draw, holding vector shapes, flowcharts, diagrams, and text boxes as editable XML. The catch is that almost nothing outside those two suites opens an ODG, so sharing one means the recipient needs Draw installed. Converting to PDF flattens the drawing into a fixed-layout document that opens in any browser, phone, or print queue while keeping the vector paths and embedded fonts crisp at any zoom.

The shapes, lines, and text in your ODG are rendered into the PDF as native vector content, so the result stays sharp at any zoom and prints cleanly. The PDF graphics model supports vector paths directly, so there is no need to rasterize the artwork. Only raster images that were already embedded in the ODG (such as a placed photo) stay as pixels, exactly as they were in the source.
PDF supports font embedding for Type 1, TrueType, and OpenType, so text in the drawing renders identically on a machine that does not have those fonts installed. In our testing, a one-page ODG flowchart built with a common sans-serif typeface produced a PDF whose labels matched the original character-for-character on a clean system with none of the source fonts present. If a font cannot be embedded for licensing reasons, the viewer substitutes a metrically similar one.
ODG is part of the OpenDocument (ODF) family standardized by OASIS and published as ISO/IEC 26300. The ISO edition 26300:2015 corresponds to ODF 1.2, and the newest specification, ODF 1.3, became an OASIS Standard in April 2021. Files saved by current and older LibreOffice and OpenOffice versions convert the same way — you do not need to know or set a version number.
ODG uses the MIME type application/vnd.oasis.opendocument.graphics and is essentially a ZIP package of XML parts that only OpenDocument-aware drawing apps — LibreOffice Draw, OpenOffice Draw, and Collabora Online — interpret natively. Microsoft Office and most image viewers do not read it. That narrow support is the main reason people convert ODG to PDF, which opens in virtually every browser and operating system.
Yes. Add all the .odg files to the queue and set the Combine option to "Single PDF" to stitch every drawing into one multi-page document in upload order. Choose "Individual PDFs" instead and each ODG becomes its own separate PDF. If you only need a fixed-layout web copy that stays editable as vectors, converting ODG to SVG is an alternative for a single drawing.
Size usually comes from high-resolution raster images embedded inside the original drawing. Lower the Image Compression quality slider in Advanced Options before converting, and pick the "Screen" or "Ebook" compression profile rather than "Prepress." If the file is already converted, you can run the result through compress PDF to reduce it further without redoing the conversion.
Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.
