ICO to TIFF Converter

Convert ICO icon files to lossless TIFF images locally in your browser. The tool extracts the highest-resolution frame from each ICO file and encodes it as a full-quality TIFF. Batch convert, preview thumbnails, download individually or as a ZIP. No uploads, no account required.

What This Tool Does

Converts ICO icon files to lossless TIFF format entirely in your browser. The browser's native ICO decoder extracts the highest-resolution frame embedded in the ICO file (typically 256×256 pixels), and UTIF encodes the pixel data as a full-quality, uncompressed TIFF. No server upload, no account, no file size limits.

Who This Is For

  • Designers who need to extract icon art from ICO files for use in print or large-format layouts
  • Archivists converting icon libraries to lossless TIFF for long-term storage
  • Developers extracting logo assets from ICO files to edit in professional image editors
  • Anyone who needs to open or import ICO art into software that only accepts TIFF

Example: Input: favicon.ico (256×256 icon) → Output: favicon.tiff (lossless, editable in Photoshop, GIMP, or Affinity Photo)

💡 Need to convert ICO to a web format? Try ICO to AVIF for modern web delivery. To create ICO from other formats, use HEIC to ICO or TIFF to ICO. For lossless resizing, use the Image Resizer.

How It Works

1
Drop your ICO filesDrag one or more .ico files onto the drop zone, or click Browse Files. Thumbnails generate immediately using your browser's native ICO decoder.
2
Click Convert to TIFFThe Canvas API renders each ICO's highest-resolution frame; UTIF encodes the RGBA pixel data as a lossless, standards-compliant TIFF in memory.
3
Download your TIFFsDownload files individually or check "Download as ZIP" for a single timestamped archive. App resets after export.

🔒 Privacy & Security

All decoding and encoding runs entirely in your browser. ICO files are never sent to any server — they stay in your browser's memory from load to download. This is especially important for proprietary brand assets and client icon files.

Frequently Asked Questions

What resolution is the output TIFF?
The TIFF is exported at the highest-resolution frame available in the ICO file. For modern ICO files this is typically 256×256 pixels. The resolution depends on what was embedded in the original ICO — the tool never upscales beyond the source data.
Does the TIFF preserve transparency?
Yes — the output TIFF is encoded as 32-bit RGBA, which fully supports alpha channel transparency. If your ICO frames have transparent backgrounds (common with icon art), those will be preserved in the TIFF output.
Can I convert multiple ICO files at once?
Yes — drop up to 25 or more files at once. The tool processes them sequentially, shows per-file status badges, and lets you download all TIFFs individually or as a single timestamped ZIP.
Is TIFF lossless?
Yes — TIFF supports lossless encoding. The output from this tool uses uncompressed RGBA encoding, preserving every pixel from the ICO source exactly. No quality is lost in the conversion.
Is this tool free with no limits?
Yes — completely free with no file size limits, no per-conversion limits, and no account required. Processing happens in your browser so we never see your files.
What is the ZIP file named?
The ZIP is named dataconversioncenter_ico_to_tiff_YYYYMMDDHHMM.zip using your local time — for example dataconversioncenter_ico_to_tiff_202603061200.zip.
