Need help?ORF to ICO Converter
ORF is the Olympus RAW format — the unprocessed sensor file an Olympus or OM System camera writes for a still photo. ICO is the Windows icon container, where each image is at most 256×256 pixels. This converter renders the raw photo to a standard image and packs it into an icon, so a frame you shot can become an app icon or a website favicon.
This is a heavy downscale: a 12- or 14-bit raw with the full sensor resolution is demosaiced, baked down to 8-bit color, and shrunk to icon size. Use it when you genuinely want an icon. To keep a viewable photo, convert to a normal image format with ORF to JPG or ORF to PNG instead.
ORF Format at a Glance
| Property | Value |
|---|---|
| Full name | Olympus RAW Format |
| Origin | Olympus / OM System (OM Digital Solutions) cameras |
| Type | Camera raw — unprocessed sensor data |

| Bit depth | Typically 12-bit or 14-bit per channel |
| Color | One-color-per-pixel sensor mosaic, not yet rendered to RGB |
| Best for | Editing latitude before export; archival of the original capture |
| Not viewable as | A finished image without rendering |
ICO Format at a Glance
| Property | Value |
|---|---|
| Full name | Windows Icon |
| Origin | Microsoft Windows |
| Max image size | 256×256 pixels per image |
| Bit depths | 1, 4, 8, 24, and 32-bit (32-bit adds an 8-bit alpha channel) |
| Multi-size | One .ico can hold several sizes (16×16, 32×32, 48×48, 256×256…) in one file |
| PNG storage | 256×256 32-bit icons are typically stored PNG-compressed (Windows Vista and later) |
| Best for | App icons, desktop shortcuts, website favicons |
How to Convert ORF to ICO
- Upload Your ORF File: Drag and drop your .orf files or click "+ Add Files"; you can queue several at once.
- Set Image Resolution: Open Advanced Options and pick an icon size from the Image resolution preset (it defaults to 256P) — 16, 32, or 48 pixels suit small UI icons, 256 suits a high-DPI app icon.
- Tune Color and Bit Depth (Optional): Adjust the color palette and bit depth if you want a smaller file or a flat-color icon; leave them on default for a full-color icon with transparency.
- Convert and Download: Click "Convert" and download your .ico. No sign-up, no watermark.
Frequently Asked Questions
Why does my Olympus photo look so much worse as an ICO?
An ICO image tops out at 256×256 pixels, and the conversion bakes your raw's 12- or 14-bit data down to standard 8-bit color. A 20-megapixel capture losing almost all of its resolution and dynamic range is expected — icons are built for small UI display, not photo viewing. If you wanted a normal picture, use ORF to JPG instead.
What icon size should I choose?
Pick the size to match where the icon appears. 16×16 and 32×32 cover toolbar and taskbar icons, 48×48 covers desktop shortcuts, and 256×256 covers high-DPI app icons and the large preview in Windows Explorer. A single .ico can hold several of these, but this converter outputs the resolution you select.
Can I use the result as a website favicon?
Yes. A .ico is the classic favicon format and is recognized by every major browser. A 32×32 or 48×48 icon works well for favicon.ico; many sites also reference a separate 16×16 for crisp display in browser tabs.
Does the conversion keep transparency?
It can. ICO supports a 32-bit mode with an 8-bit alpha channel, which gives smooth anti-aliased edges. An ORF photo has no alpha to begin with, so the frame fills the icon; if you need a cut-out icon with a transparent background, render to PNG first, edit out the background, then convert that PNG to ICO.
Will I keep my camera's EXIF or color profile?
No. Icons do not carry photographic metadata. The shutter speed, ISO, lens, and embedded color profile from the ORF are dropped when the image becomes an icon. Keep the original .orf if you need that data, and export a JPG or TIFF for any version that should retain EXIF.
Is converting ORF to ICO online private?
Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and files are never shared or made public. In our testing, a single-frame ORF rendered to a 256×256 ICO completes in a few seconds.
