What to know about DDS to ICO conversion
- ICO is lossless: it stores the decoded image exactly, which usually makes files larger than the original DDS, but prevents further quality loss when you edit again.
- Transparency is preserved: ICO supports an alpha channel just like DDS.
- Images larger than 256×256 pixels are scaled down automatically, the maximum size of a Windows icon.
- ICO is best for website favicons and Windows icons, and opens in browsers, Windows and icon editors.

Frequently asked questions
Is it safe to convert DDS to ICO here?
Yes. Your files are processed entirely on your own device by WebAssembly code running in the browser. They are never uploaded, so nobody else can see them, and the converter keeps working even if your connection drops after the page loads.
Is there a file size limit?
There is no server-side limit. The only limit is the memory available to your browser, typically 1.5–4 GB on desktop computers.
Can I convert several DDS files at once?
Yes. Add as many files as you like; they are converted in parallel according to your device's CPU cores, and you can apply the same settings to all of them.
