ICO to CIN Converter
Processing entirely on your device — large files may take a moment.
Windows Icon and Cineon exist for different jobs: ICO is the Windows icon format. A single ICO file can bundle several sizes (16×16 up to 256×256) of the same icon, used for shortcuts, application icons and website favicons. Convert CIN film scans to PNG/JPG, or write CIN for film-pipeline compatibility.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the ICO format
ICO is the Windows icon container, and one of the oldest formats still in daily use. A single ICO file bundles several renderings of the same icon — 16×16, 32×32, 48×48 up to 256×256 — so Windows can pick the right sharpness for shortcuts, Explorer views and taskbars. Each member is stored as classic BMP data or, for large sizes, PNG compression.
On the web, favicon.ico at the site root remains the one icon request every browser makes automatically, which keeps the format alive despite cleaner alternatives like PNG and SVG icons. Keep ICOs small: every visitor downloads one.
+ Strengths
- ✓Multiple sizes bundled in one file
- ✓Every browser falls back to /favicon.ico automatically
- ✓Deep Windows integration for app icons
! Limitations
- −Practical size ceiling around 256×256
- −Windows-centric; little use outside icons
- −Quality is frozen at export time
About the CIN format
The Cineon coder of the ImageMagick set — the film-pipeline format is written natively by the magick.wasm engine, entirely in your browser.
Obscure coder formats like this are exactly what template-driven converters list and never actually convert — here it really works.
+ Strengths
- ✓Written natively by ImageMagick
- ✓Runs entirely in your browser
- ✓Free, private, no watermarks
! Limitations
- −Niche format — few modern readers
- −Feature subset varies by coder
- −Keep the original for re-editing
Why convert ICO to CIN?
Converting makes sense where the strengths of CIN meet what ICO cannot give you. Written natively by ImageMagick Meanwhile Practical size ceiling around 256×256 One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this ICO to CIN converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting ICO to CIN?
No — CIN is a lossless format, so every pixel of the converted image matches your original ICO file. You can also adjust the quality/size balance before converting when the target format supports compression.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your ICO files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Will transparent areas survive the conversion to CIN?
Transparency is kept whenever CIN actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
