ODG is the OpenDocument Graphics format used by LibreOffice Draw and Apache OpenOffice Draw — a vector drawing document that can hold shapes, text, and embedded images, sometimes across more than one page. ICO is the Windows icon container, capped at 256×256 pixels per image. This converter renders a page of your drawing to a raster image and shrinks it into an icon, which is exactly what you need to turn a Draw logo into a favicon or desktop icon.
What Happens When You Convert ODG to ICO
An ODG is a resolution-independent drawing; an ICO is a fixed, tiny bitmap. The conversion rasterizes the drawing — vector shapes and text become fixed pixels — and then downscales the result to icon dimensions. That shrink is the part worth understanding:
- 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 — fine text, several small objects, thin lines — becomes unreadable once it is squeezed to 256×256 or smaller. There is simply not enough pixel room.
- If your drawing has more than one page, the converter renders a page to the canvas rather than stitching the whole document into one icon. For a viewable, full-size image keep the resolution high with ODG to PNG (which preserves transparency) or ODG to JPG; for the entire document use ODG to PDF.

How to Convert ODG to ICO
- Upload Your ODG File: Drag and drop your .odg drawing onto the page or click "+ Add Files" to pick it from your computer.
- Set the Image Resolution: Use the Image Resolution preset to choose the icon size — 256P (256×256) is the default and the largest an ICO supports; drop to 32 or 16 for a classic favicon footprint.
- Refine in Advanced Options: Expand Advanced Options to adjust render DPI, color palette, and bit depth if you want a smaller, flatter icon; otherwise the optimized defaults are fine.
- Convert and Download: Click "Convert" and download your .ico. No sign-up, no watermark.
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 becomes a blur once it is downscaled. If you need the artwork to stay legible at full size, convert to ODG to PNG instead and keep it as a regular image.
Does the ICO keep the transparency from my drawing?
It can. The ICO format supports a full 8-bit alpha channel, so a logo on a transparent background can stay transparent through the conversion. In our testing, a flat logo drawn on no background produced a 256×256 icon with clean transparent corners — useful for favicons that sit on colored toolbars.
What size should I pick for a favicon?
A favicon is most commonly rendered at 16×16, 32×32, or 48×48. ICO is the format MDN recommends for favicons precisely because it has the broadest browser support and can hold several of those sizes in one file. Picking 256P here gives you the largest, sharpest source the format allows, which browsers downsample as needed.
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/application icon, ICO is the right target. If you only need a web image, ODG to PNG is simpler.
My drawing has several pages — which one becomes the icon?
The converter rasterizes a page of the drawing to the canvas rather than merging every page into one icon, since an icon is a single small image. If you want the whole multi-page document preserved, convert it with ODG to PDF instead.
Is the ODG specification still maintained?
Yes. OpenDocument is an active ISO/IEC standard (ISO/IEC 26300), first approved by OASIS in May 2005, with ODF 1.3 as the current published version. Files saved by recent LibreOffice Draw releases convert without issue.
Is the conversion private?
Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and your files are never shared or made public.
What do the Advanced Options (DPI, colour palette, bit depth) change?
They control how the icon is rendered and how heavy the file is. Render DPI sets how finely the vector drawing is rasterized before it is scaled to the icon size, while reducing the colour palette or bit depth produces a smaller, flatter .ico at the cost of colour range — fine for a simple flat logo. If you are unsure, the optimized defaults already produce a clean icon, so you only need these controls for a specific size or colour budget.
