What DDS compression formats are supported?

This tool supports DXT1 (BC1), DXT3 (BC2), DXT5 (BC3), BC4 (ATI1), BC5 (ATI2), BC7, and uncompressed RGBA/BGRA/RGB DDS formats. Cubemap and volume texture DDS files are not currently supported.

Why convert DDS to ICO?

ICO is the standard format for Windows application icons and browser favicons. Game developers and modders often want to use a DDS texture — such as a game logo or character portrait — as an icon or favicon, making DDS to ICO conversion the right step.

Can I convert multiple DDS files at once?

Yes — this tool supports batch conversion. Drop up to 25+ files at once, monitor per-file status, then download individually or as a single ZIP archive.

Does my data get uploaded to a server?

Never. All DDS decoding and ICO encoding happens entirely in your browser using JavaScript. Your files never leave your device.

DDS to ICO Converter

Convert DirectDraw Surface (DDS) game texture files to ICO icon format entirely in your browser. Supports DXT1, DXT3, DXT5, BC4, BC5, BC7, and uncompressed DDS formats. Each ICO output contains six embedded PNG frames (16–256 px). Batch convert, preview thumbnails, download individually or as a ZIP. No uploads, no account required.

What This Tool Does

Converts DDS (DirectDraw Surface) texture files — the standard compressed image format used in DirectX games and 3D applications — to ICO icon format entirely in your browser. Handles DXT1/BC1, DXT3/BC2, DXT5/BC3, BC4 (single-channel), BC5 (dual-channel normal maps), BC7 (high-quality), and uncompressed RGBA/BGRA formats. Each ICO output contains six embedded PNG frames at standard sizes (16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 pixels). No server upload, no account, no file size limit imposed by a backend.

Who This Is For

Game developers who need a Windows application icon or favicon from a DDS texture asset
Modders converting game logo or UI textures into ICO files for custom launchers
3D artists turning DDS sprite sheets or portraits into multi-size icon assets
Web developers who want to use a game texture as a favicon without installing software

Example: Input: game_logo.dds (DXT5 texture) → Output: game_logo.ico (multi-size icon, ready for favicon or Windows app use)

💡 Need a lossless editable format instead? Try DDS to TIFF for Photoshop-compatible output. For modern web delivery, use DDS to AVIF. For iPhone icon conversions, see HEIC to ICO.

How It Works

Drop your DDS filesDrag multiple .dds files onto the drop zone, or click Browse Files. The DDS header is parsed immediately to detect the compression format (DXT1, BC7, etc.) and generate a preview thumbnail.

Click Convert to ICOThe pure-JS DDS decoder decompresses each texture to raw RGBA pixel data. The ICO encoder then scales it to six standard sizes and builds a standards-compliant ICO blob in memory.

Download your ICOsDownload 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. DDS files are never sent to any server — they stay in your browser's memory from load to download. This is especially important for proprietary game assets and unreleased textures.

Frequently Asked Questions

What DDS formats are supported?▼

This tool supports DXT1 (BC1), DXT3 (BC2), DXT5 (BC3), BC4 (ATI1), BC5 (ATI2), BC7, and uncompressed RGBA/BGRA DDS formats. Cubemap and volume texture DDS files are not currently supported.

What sizes does the output ICO contain?▼

Each ICO file contains six PNG frames: 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256 pixels. Windows and browsers automatically select the most appropriate size for the context.

Can I use the ICO as a favicon?▼

Yes — ICO is the original favicon format. Rename the output to favicon.ico and place it in your website root. All browsers will use it automatically, selecting the most appropriate embedded size.

Can I convert multiple files at once?▼

Yes — drop up to 25 or more files at once. The tool processes them sequentially, shows per-file status badges and detected DDS format, and lets you download all ICOs individually or as a single timestamped ZIP.

Does the ICO support transparency?▼

Yes — the ICO frames are encoded as 32-bit RGBA PNG, which supports full alpha channel transparency. If your DDS source uses DXT5 or BC7 with an alpha channel, transparency is preserved in the ICO output.

What is the ZIP file named?▼

The ZIP is named dataconversioncenter_dds_to_ico_YYYYMMDDHHMM.zip using your local time — for example dataconversioncenter_dds_to_ico_202603051709.zip.
