ODG to WebM Converter

Convert ODG to WebM Online

An ODG is an OpenDocument Graphic — an editable vector drawing of shapes, lines, and text from LibreOffice Draw or Apache OpenOffice Draw, usually a flowchart, diagram, or poster. WebM is an open web video container that browsers and web players understand but that expects moving frames. This is a two-stage conversion: the vector drawing is first rasterized to a fixed grid of pixels, then that single frame is held on screen for a duration you choose, producing a short, motionless WebM with no audio. It is the right tool when something downstream needs a video file — a web player, a video-editing timeline, or a slot that only accepts .webm — and you want to drop a diagram in as a title card or slate. If you just need a viewable picture, ODG to PNG is simpler; to keep the drawing scalable, ODG to SVG preserves the vectors.

How to Convert ODG to WebM

1. Upload Your ODG File: Drag and drop your .odg drawing onto the page, or click "+ Add Files" to browse. You can queue several files at once to convert them in a batch.
2. Set the Duration: Open Advanced Options and use Duration to choose how many seconds the frame is held — 5 seconds per frame is the default. Because there is only one image to show, this is the full length of the resulting clip.
3. Pick Resolution, Codec, and Background (Optional): Under Video resolution, keep the original render size or set an exact width and height — choose the pixel size you need now, because enlarging the WebM later pixelates it. Video Codec stays on VP9 unless you switch it to VP8, and Background Color (Black by default) fills any area the drawing does not cover.
4. Convert and Download: Click "Convert" and download your WebM. No sign-up, no watermark.

Frequently Asked Questions

Will my ODG to WebM clip actually move or play an animation?

No. An ODG drawing page is a single still illustration, not a sequence of frames, so converting it produces a motionless WebM — one rasterized image held on screen for the duration you set, with nothing animating and no audio. That is by design: the value is wrapping a static diagram in a web-playable video container, for example to use a flowchart as an intro slate or a placeholder card in a video workflow. Real motion has to be built from a video or an image sequence, not from a single drawing page.

Why does my drawing stop being editable and lose sharpness when enlarged?

Because ODG stores resolution-independent vector objects, but the moment it becomes a WebM frame it is flattened into a fixed grid of pixels locked to the dimensions you chose. The shapes, lines, and text boxes are no longer separate objects you can move, and enlarging the clip past its rendered size softens and pixelates it because there is no vector data left to redraw from. Set Video resolution to the size you actually need before converting, and keep the original .odg as your master. To keep the artwork scalable instead, convert ODG to SVG, which preserves the vector shapes.

What happens to a multi-page ODG when I convert to WebM?

Treat one drawing page as one clip. A WebM holds a single video stream, so this conversion is built around a single rasterized frame rather than stitching several drawing pages into one timeline. If your file has multiple pages and you need them all in one document, ODG to PDF keeps every page in a single file; if you need a still image of each page, ODG to PNG renders them as raster images. For a slate or title card, export the single page you want as its own ODG first.

Which WebM codec does this output, and why VP9?

VP9 by default, with VP8 available under Video Codec. VP9 is the newer of the two open, royalty-free codecs that the WebM Project specifies, and it compresses flat-color line art and diagrams efficiently while staying playable in current versions of Chrome, Firefox, Edge, and Opera, plus Safari 14.1 and later. VP8 is older and slightly more broadly compatible with very old players, so switch to it only if a specific legacy target rejects VP9.

I just need a still picture of my ODG — is WebM the right choice?

Probably not. WebM is a video container, so you only want it when something downstream specifically expects a video file. If you simply need a viewable still image of the drawing, ODG to PNG gives you a lossless raster image that opens everywhere with no video overhead, and it renders the hard edges and flat fills of a diagram cleanly. Reach for ODG to WebM only when the target genuinely needs a .webm.

How are my uploaded files handled?

Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion. There is no sign-up, no watermark, and files are never shared or made public. In our testing, a single-page A4 flowchart with a handful of fill colors rendered to a short VP9 WebM in a couple of seconds; a large, detail-heavy drawing at a high output resolution takes longer to upload and encode.
