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.

Does my data get uploaded to a server?

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

DDS to WEBP Converter

Convert DDS game texture files to WEBP format locally in your browser. Full transparency support — alpha channels from DXT5 and BC7 textures are preserved in the WEBP output. Batch convert, preview thumbnails, adjust quality, download individually or as a ZIP. No uploads, no account required.

What This Tool Does

Converts DDS (DirectDraw Surface) game texture files to WEBP format entirely in your browser. Supports the full range of BCn compressed formats — DXT1, DXT3, DXT5, BC4, BC5, BC7 — as well as uncompressed RGBA and BGRA layouts. Unlike JPG conversion, WEBP preserves full alpha channel transparency from DXT5 and BC7 sources. No server upload, no account, no file size limits imposed by a backend.

Who This Is For

Game modders who need shareable web previews of DDS texture assets with transparency intact
Web developers embedding game textures in wikis, portfolios, or press kits using the modern WEBP format
Artists and designers converting DDS source art to WEBP for delivery to clients or collaborators
Anyone who needs a universally viewable WEBP from a DDS file without installing heavyweight tools

Example: Input: character_diffuse.dds (DXT5 texture with alpha) → Output: character_diffuse.webp (WEBP with full transparency preserved)

How It Works

Drop your DDS filesDrag one or more .dds files onto the drop zone, or click Browse Files. The tool detects DDS format (DXT1, BC7, etc.) and generates a thumbnail immediately.

Set quality and optionsAdjust the quality slider (default 85%). Higher values preserve more detail; lower values reduce file size. Enable ZIP mode to bundle all outputs into one download.

Download your WEBPsClick Convert to WEBP. The BCn decoder decompresses each texture and the WEBP encoder writes the output in memory — download files individually or as a timestamped ZIP.

🔒 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, unreleased textures, and NDA-covered content.

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.

Does WEBP preserve DDS transparency?▼

Yes — WEBP fully supports an alpha channel, so transparency from DXT5 and BC7 DDS textures is preserved exactly in the output. This is one key advantage WEBP has over JPG for DDS conversion.

What quality setting should I use?▼

85% (the default) strikes a well-established balance between visual quality and file size. Use 90–100% for maximum fidelity or archiving. Use 70–80% to minimise file size for web delivery where bandwidth matters. WEBP at 85% typically produces smaller files than JPG at the same perceived quality.

Can I convert multiple DDS files at once?▼

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

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_dds_to_webp_YYYYMMDDHHMM.zip using your local time — for example dataconversioncenter_dds_to_webp_202603061200.zip.
