What This Tool Does
This tool loads an ICO image directly in your browser, presents an interactive crop overlay with draggable handles, and converts the selected area to a TIFF file. No server upload is required. The full workflow — loading, cropping, and TIFF encoding — runs entirely in client-side JavaScript using the HTML5 Canvas API. ICO files are decoded by drawing them to an offscreen canvas, ensuring complete pixel data is available before the crop overlay is drawn. The output is a baseline uncompressed TIFF encoded using a JavaScript TIFF writer, supporting full RGBA output with a complete alpha channel.
Who This Is For
- Print designers who need to convert an ICO icon region to TIFF for use in professional publishing workflows
- Archivists who require lossless TIFF output from icon assets for long-term storage
- Anyone who needs to extract and convert a portion of an ICO to TIFF without installing dedicated software
- Content creators who want a quick, privacy-respecting crop-and-convert tool that needs no account or upload

Frequently Asked Questions
TIFF (Tagged Image File Format) is a professional lossless image format widely used in print, archiving, and publishing workflows. ICO files are Windows icon containers. Converting a cropped ICO region to TIFF produces a high-quality, lossless file suitable for professional editing and print production.
Yes — the tool provides an interactive crop overlay on the source image. Drag the corner and edge handles to define exactly which portion of the ICO you want in the output TIFF. Click Preview Crop to see the result before downloading.
No. All processing — loading, cropping, and TIFF encoding — happens entirely in your browser using JavaScript and the HTML5 Canvas API. Your image never leaves your device.
The tool encodes a baseline uncompressed TIFF using a JavaScript TIFF writer. The cropped pixel data is read from an HTML5 canvas and written into a valid TIFF byte stream with proper IFD headers, supporting full RGBA output.
The tool is limited by your browser's available memory. ICO files are typically small (16×16 to 256×256 px), so processing is fast on all modern browsers.
Click the Start Over button that appears after loading an image. This clears the current file and resets the crop area so you can load a new ICO.
