ODG to PNG Converter

ODG to PNG Converter

ODG is the OpenDocument Drawing format that LibreOffice Draw and Apache OpenOffice Draw save — a vector file holding shapes, connectors, diagrams, and flowcharts as editable XML. PNG is a lossless raster image that opens in virtually any browser, image viewer, or document editor without LibreOffice installed. Converting flattens the drawing into a fixed grid of pixels: the result is no longer infinitely scalable or click-to-edit, but it is portable and, unlike JPG, lossless — so flat fills and sharp diagram lines stay crisp, and a drawing with no page background can keep a transparent one.

How to Convert ODG to PNG

1. Upload Your ODG File: Drag and drop your .odg onto the page, or click "+ Add Files" to browse. You can queue several drawings to convert with one set of settings.
2. Set the Quality Preset: Open Advanced Options and leave Quality Preset on "Very High" for the sharpest output, or lower it to shrink the file.
3. Choose Resolution (Optional): Use Image resolution to scale by percentage, keep the original size, or pick a preset or exact Width x Height so the PNG matches where you'll place it.
4. Convert and Download: Click "Convert" and save the PNG. No sign-up, no watermark. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion.

Frequently Asked Questions

Will my ODG drawing lose quality when it becomes a PNG?

PNG uses lossless compression, so the conversion itself adds no compression artifacts — flat colors and diagram lines reproduce exactly at the chosen size. The real change is that vector geometry is rasterized into pixels at a fixed resolution. At a generous size the result looks identical to the original on screen; the only loss is scalability, since enlarging a PNG past its pixel dimensions softens the edges.

Does the PNG keep a transparent background?

PNG supports an alpha channel, so transparency can survive the conversion. It depends on the source: if your ODG page has no background fill, the exported PNG can carry that transparency through as truecolour-with-alpha. If the drawing has a solid page color, that color is baked into the PNG as opaque pixels. If you need guaranteed transparency, set the page background to "None" in LibreOffice Draw before exporting.

Should I convert to PNG, or keep the drawing as a vector?

Convert to PNG when you need a finished, portable image to drop into a webpage, chat, slide, or document — it opens everywhere without LibreOffice. Keep a vector format when you still want to scale or edit the artwork. For that, convert ODG to SVG to stay editable on the web, or convert ODG to PDF for a print-ready, resolution-independent page. PNG is the right pick only once the drawing is final.

What resolution or size should I export at?

Match the pixels to where the image will live. For on-screen use and web embedding, the original size or a percentage scale is usually fine. For print or for zooming into fine diagram detail, scale up first using Image resolution or an exact Width x Height, because a PNG cannot be sharply enlarged after the fact the way the original vector could. In our testing, a single-page A4 ODG flowchart exported at roughly screen resolution lands in the low hundreds of kilobytes.

Why is my multi-page ODG only producing one image?

PNG is a single-image format and has no concept of pages, so each page of a multi-page ODG drawing maps to its own PNG rather than one combined file. If you want every page held together in one document, convert ODG to PDF instead, which preserves multiple pages in a single file.

Can I edit the shapes again after converting to PNG?

No. Once rasterized, the drawing is a flat grid of pixels — individual shapes, text, and connectors are no longer separate selectable objects. To keep editing in Draw, hold onto the original .odg; to edit on the web while staying scalable, convert to SVG instead.
