ODG to WebM Converter

Convert ODG to WebM Online

An ODG is an OpenDocument Graphics drawing — editable vector shapes, lines and text from LibreOffice Draw or Apache OpenOffice Draw, usually a flowchart, diagram or poster. WebM is the open, royalty-free web video container that browsers play natively. This conversion renders the drawing and holds each page on screen as a silent, motionless clip, which is what you want when a web player, an HTML5 <video> element or a slot that only accepts .webm needs a diagram dropped into it as a slate or title card.

How to Convert ODG to WebM

1. Upload Your ODG File: Drag the .odg onto the page or click "+ Add Files". Queue several and Merge strategy decides between one WebM showing each drawing in turn ("Merge images") and one file per upload ("Video per image").
2. Set the Duration: Image Duration → Duration controls how long each rendered page is held — 5 seconds unless you change it, with options from a 1/60-second frame up to 10 seconds. That is the whole length of the clip.
3. Pick the Codec, Resolution and Background: Video Codec offers VP9 (preselected), VP8 and AV1. Video resolution opens on "Keep original" — switch to Fixed Resolutions → 1920 x 1080 for a standard web frame — and Background Color, White by default, fills any area the page does not cover.
4. Convert and Download: Click "Convert" and save the WebM. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. No sign-up, no watermark.

What the Conversion Actually Does

LibreOffice opens the .odg as a Draw document, exports it with Draw's own PDF filter, and each page of that PDF is rendered at 300 DPI into the frames the encoder receives. An A4 page therefore arrives near 2480 x 3508 pixels, so asking for a 1080p frame scales the render down and keeps thin lines clean. The vectors stop being vectors at that render step: after it the WebM holds flat pixels locked to the size you chose, and no shape can be selected or moved again. Page count survives — a three-page drawing becomes three held frames in one clip.

Frequently Asked Questions

Will the WebM actually move or play an animation?

No. A drawing page is a single still illustration, not a sequence of frames, so the result is a motionless clip: one rendered image per page, held for the duration you set, with no audio. That is the point of the format pairing — it wraps a static diagram in something a web player will accept. Real motion has to come from a video source or an image sequence.

Why does the drawing stop being editable and soften when enlarged?

Because ODG stores resolution-independent objects and a WebM frame is a fixed grid of pixels. Once the page is rendered, the shapes, lines and text boxes are no longer separate objects, and enlarging the clip past its rendered size resamples pixels rather than redrawing vectors. Set Video resolution to the size you need before converting, keep the .odg as the master, and use ODG to SVG when the artwork itself has to stay scalable.

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

Each drawing page becomes a held frame inside the same clip, in page order. A WebM holds one video stream, so the pages appear in sequence rather than as separate files — three pages at the 5-second default give a 15-second clip. Upload the pages as separate files and choose "Video per image" if you want one WebM each.

Which codec should I leave it on, and why VP9?

VP9 by default. It is the newer of the two long-standing royalty-free WebM codecs, compresses flat-colour line art efficiently and plays in current Chrome, Firefox, Edge and Opera plus Safari 14.1 and later. VP8 is older and reaches a few more ancient players; AV1 compresses harder still but is slower to encode and less universally decoded. For a five-second still the difference in file size is academic — pick VP8 only if a specific legacy target rejects VP9.

Will the WebM import into Premiere Pro, After Effects or PowerPoint?

Not reliably. WebM plays in every modern browser, but desktop tools are another matter: Premiere Pro and After Effects do not import .webm without a third-party plugin, and PowerPoint's video insert expects MP4 or WMV. If the diagram is headed for a desktop timeline or a slide deck rather than a web page, ODG to MP4 writes an H.264 clip those tools accept directly.

Will the fonts and colours render exactly as they look in Draw?

Colours and shapes render as drawn, because they are stored in the file itself. Fonts are the thing to watch: the drawing is rendered on our servers, and a typeface that is not available there can be substituted, which shifts text spacing and line breaks. Converting the text to curves in Draw (Shape ▸ Convert ▸ To Curve) before uploading removes the risk entirely.

I just need a picture of the drawing — is WebM right?

Probably not. WebM is a video container, worth choosing only when something downstream specifically expects a video file. For a still picture of the same drawing, ODG to WebP gives you the web-weight image the same project probably wants, and ODG to PNG gives you the lossless one.

How are my uploaded files handled?

They travel over an encrypted connection, are processed on our servers, and are deleted automatically a few hours after conversion. Nothing is shared or made public, no account is required, and no watermark is applied. A large, detail-heavy drawing at a high output resolution simply takes longer to upload and encode — the practical limit is upload time, not the drawing's complexity.
