ODG to ASF Converter

ODG to ASF Converter

An .odg is an OpenDocument Graphics drawing — the vector shapes, connectors and text frames LibreOffice Draw and Apache OpenOffice Draw store as XML inside a ZIP package. ASF, the Advanced Systems Format, is Microsoft's streaming container: the wrapper that .wmv video and .wma audio live inside, designed in the Windows Media era for network delivery rather than for editing. This converter renders the Draw document through the office pipeline and holds each rendered page as a frame inside a silent ASF file. Both formats are described in full below, because a page-layout document and a streaming container are unusual partners and it is worth knowing exactly what you are getting.

How to Convert ODG to ASF

1. Upload Your ODG File: Drag the .odg onto the page or click "+ Add Files". The whole Draw document is read, so multi-page files need no preparation.
2. Pick a Video Codec: "Video Codec" is the widest list on any of our ASF pages — H.264 is preselected, with WMV 1, WMV 2, MPEG-1, MPEG-2, MPEG-4, Xvid, DivX, MJPEG, Theora, VP8, VP9, AV1 and several H.26x variants alongside it. Choose WMV 2 if a genuinely old Windows Media pipeline is the destination.
3. Set File Compression and Video resolution: "File Compression" opens on "Quality Preset" at "Very High (Recommended)", with Constant Quality and Constraint Quality available if you would rather drive a quantizer and cap the bitrate directly. "Video resolution" starts on "Keep original" and takes a preset height, a percentage or an explicit Width x Height.
4. Convert and Download: Click "Convert" and save the .asf. 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 Pipeline Actually Does

A .odg is a document, not a picture, so it does not go through an image converter. LibreOffice Draw's own PDF export filter reads the drawing and writes a PDF that preserves the document's page size and object positions; each PDF page is then rendered to a full-colour raster at 300 DPI; finally ffmpeg assembles those renders into a slideshow and muxes it into ASF. Because the render follows the Draw page's physical size rather than any stored pixel count, a US Letter page arrives near 2550 × 3300 px and A4 near 2481 × 3507 px — "Video resolution" is the control that brings that to whatever your player expects.

Frequently Asked Questions

Is ASF the same thing as WMV?

Not quite — ASF is the container and WMV is a codec that usually travels inside it. A .wmv file is an ASF file whose video track is Windows Media Video, and a .wma is an ASF file carrying Windows Media Audio. Naming a file .asf is the generic form, which is why the codec list on this page is so long: the container will happily carry H.264 or MPEG-4 as well as WMV.

Which codec should I choose inside the ASF?

H.264 unless something specific tells you otherwise. It is preselected, compresses a rendered page well, and any current player that opens ASF at all will decode it. Pick WMV 2 when the destination is an older Windows Media pipeline that expects a Microsoft codec, and MPEG-4 or Xvid when a device lists those by name. The container does not change what the drawing looks like; the codec and the resolution do.

My Draw file has several pages — do they all end up in the ASF?

Yes, as successive held frames in one clip, in page order. The office stage exports every page to PDF and each page is rendered, so nothing is dropped and there is no need to split the document first. If you would rather have separate pictures, an image target such as ODG to JPG returns one file per page.

Why does the file have no audio track?

Because the source has none. An OpenDocument drawing stores shapes and text, not sound, so no audio is encoded — the silence comes from the input, not from ASF, which was built to carry Windows Media Audio. To add a soundtrack, convert here and then mux an audio track over the clip in a video editor.

Will an ASF play in a browser or on a phone?

Generally not. No current browser plays ASF in a <video> tag, and mobile platforms do not include a Windows Media stack. Desktop players built on ffmpeg — VLC and mpv among them — open the file without complaint, and so does Windows Media Player on Windows. If the clip needs to reach a browser, a phone or a TV, ODG to MP4 is the container to use.

Does the drawing keep its transparent background?

No. Video has no alpha channel, so transparent areas are flattened onto an opaque background before the frame is encoded, and the same fill covers any bars left when the page's proportions do not match the chosen frame. If the transparency matters, use an image target with an alpha channel such as ODG to PNG.

Is the drawing still editable after conversion?

No, and it cannot be made so. ODG stores every element as a distinct object with its own style; a video frame is a flat grid of samples with no memory that a rectangle was ever a rectangle. Keep the original .odg as your master. If you need a portable file that still holds real geometry and selectable text, ODG to PDF is the right target.

Is ASF still being developed?

Not in any active sense. ASF belongs to the Windows Media generation and Microsoft's own modern tooling has long since moved to MP4 and fragmented MP4 for streaming. It persists in archives, in broadcast and surveillance equipment of a certain age, and in software whose accepted-formats list has not been revised. That is a reasonable use case — it is just not a reason to pick ASF for anything new.

How are my uploaded files handled?

Your .odg travels over an encrypted connection, is rendered and encoded on our servers, and is deleted automatically a few hours later along with the ASF it produced. Nothing is shared, published or reused, no account is required, and no watermark is applied. The ODG converter hub lists every other target this source can be pointed at.
