Why convert PDF to ICO?
Introduced in 1993 by Adobe, PDF was great for its time. But ICO (created in 1985 by Microsoft) offers lossless compression and 32-bit – a massive leap forward. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches.
