Convert Other Formats to WebP
Beyond the common formats, there are dozens of specialised image types — DDS (game textures), HDR (high dynamic range), TGA (graphics), PCX, XBM, and more. Most of these were never intended for the web. Converting them to WebP gives you a single, modern, well-supported format that works everywhere.
Usage Scenarios
- Migrating game development assets (DDS textures, TGA sprites) to web-friendly formats
- Publishing scientific visualisations from legacy formats like PBM, PGM, and RAS
- Archiving obscure-format image collections before they become unreadable
Tips
- ▸HDR images lose their extended dynamic range — the output is tone-mapped to 8-bit
- ▸Most legacy formats convert cleanly; test a sample batch before processing a large archive
- ▸For best results, convert to an intermediate format (PNG) first if a format fails directly
