Is it safe to convert my PDF files here?

Yes, completely safe. Unlike most online converters that upload your files to a remote server, this tool runs entirely in your browser using WebAssembly. Your files never leave your device and are never stored, logged, or transmitted anywhere.

What resolution will the ICO output be?

When converting from a vector format like PDF, the engine renders at the dimensions defined in the file. For best results, ensure your PDF file has an explicit width and height set. You can also pre-scale the vector before converting if you need a specific pixel size.

Can I convert multiple PDF files to ICO at once?

Yes - you can upload up to 20 PDF files at once. They all convert simultaneously and you can download them individually or as a single ZIP bundle.
