ODG to ICO Converter

Convert a Draw Logo into a Windows Icon

ODG is the OpenDocument Graphics format used by LibreOffice Draw and Apache OpenOffice Draw — a vector drawing document holding shapes, text and embedded images across one or more pages. ICO is the Windows icon container, capped at 256 × 256 pixels per image. This converter renders your Draw document and shrinks each rendered page into an icon, which is exactly what you need to turn a logo drawn in Draw into a favicon or a desktop icon. The whole page has a single control, and understanding what it does is most of the job.

How to Convert ODG to ICO

1. Upload Your ODG File: Drag your .odg onto the page or click "+ Add Files" to pick it from your computer. The whole Draw document is read, so a multi-page file returns one icon per page.
2. Pick a Preset Resolution: The Image resolution preset list is the only control this conversion exposes — 256P is the default and the largest an ICO can hold. Drop to 32 or 16 for a classic favicon footprint.
3. Check the Shape Before Converting: The preset sets the icon's height and lets the width follow your drawing's aspect ratio, with nothing cropped or padded, so a landscape Draw page at 256P comes out wider than the 256 px an ICO directory entry can declare. Draw on a square page, or step down a preset.
4. Convert and Download: Click "Convert" and download the .ico. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. No sign-up, no watermark.

What Happens When You Convert ODG to ICO

An ODG is a resolution-independent drawing; an ICO is a fixed, tiny bitmap. The conversion runs through the office pipeline — LibreOffice Draw's PDF export filter reads the drawing and writes a PDF that keeps the page geometry, each page is rendered to a raster at 300 DPI, and that render is scaled down and written as an icon. The shrink is the part worth thinking about:

• A single bold graphic — a logo, a monogram, one clear shape — reproduces cleanly at icon size and makes a sharp favicon or app icon.
• A detailed multi-element drawing with fine text, several small objects and thin lines becomes unreadable once it is squeezed to 256 × 256 or smaller. There is simply not enough pixel room, and no setting recovers it.
• Anything larger than 256 pixels is clamped to 256, because that is the maximum an ICO directory entry can describe. Asking for 4320p does not produce a bigger icon; it produces the same 256-pixel one.
• For a viewable, full-size picture rather than an icon, ODG to PNG gives a lossless image with transparency intact, and ODG to PDF keeps the whole document as vectors.

Frequently Asked Questions

Will my ODG drawing be readable as an icon?

Only if it is simple. ICO tops out at 256 × 256 pixels, so a single bold logo or symbol stays crisp, but a busy drawing with small text or many objects blurs into noise once it is downscaled. Design for the size: an icon that has to work at 16 × 16 needs one shape and maybe two colours. If you need the artwork legible at full size, ODG to PNG keeps it as a regular image with transparency intact.

Does the ICO keep the transparency from my drawing?

It can. The ICO format supports a full 8-bit alpha channel, so a logo drawn on a transparent background can stay transparent through the conversion — useful for favicons that sit on coloured toolbars. Whether a given area is genuinely transparent depends on the source: check Page ▸ Page Properties ▸ Background in LibreOffice Draw, because a page with a fill set produces an opaque render no matter what the target format supports.

What size should I pick for a favicon?

Favicons are most commonly rendered at 16 × 16, 32 × 32 or 48 × 48. Picking 256P here gives you the largest, sharpest source the format allows and lets browsers downsample as needed, which is usually the right call — but check the shape first, because the preset sets height and lets width follow the drawing's aspect ratio. A square Draw page is the safest input.

Why does my icon come out wider than 256 pixels?

Because the preset controls height, not both dimensions, and nothing is cropped or padded to force a square. A landscape page at 256P produces a 256-pixel-tall image whose width follows the original proportions, which is wider than an ICO directory entry can declare. Fix it at the source: set a square page size in LibreOffice Draw and re-save before converting, or choose a smaller preset so the width stays under the limit.

Why convert ODG to ICO at all instead of straight to PNG?

PNG is a single-resolution image; ICO is a Windows-native icon container that browsers and Windows treat as a "real" icon. If you specifically need a favicon.ico or a desktop or application icon, ICO is the right target. If you only need a web image — including for the modern <link rel="icon"> PNG route — ODG to PNG is the simpler answer.

My drawing has several pages — which one becomes the icon?

Each of them becomes its own icon, in page order. The office stage renders every page, so a three-page Draw document produces three .ico files rather than one icon with three sizes packed inside it. If you want a single multi-size icon, assemble it with a dedicated icon editor after exporting the sizes you need.

Is the ODG specification still maintained?

Yes. OpenDocument is an active standard published by OASIS and standardised as ISO/IEC 26300, with ODF 1.3 approved as an OASIS Standard in 2021. Files saved by recent LibreOffice Draw releases convert without issue, and the format remains fully editable in free software on Windows, macOS and Linux.

Why are there no colour-palette, DPI or bit-depth options here?

Because none of them apply to this target. The colour-palette control belongs to GIF output, the bit-depth control is for the Netpbm family, and the quality preset and file-size controls are hidden because ICO frames are stored as bitmap or PNG data with no lossy quality dial to turn. Resolution is the only setting that meaningfully changes an icon, so it is the only one the page renders.

Is the conversion private?

Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours along with anything it produced. There is no sign-up, no watermark, and your files are never shared or made public. The ODG converter hub lists every other target for this source.
