File Type Questions

Can you add support for [file type]?

We're constantly adding support for new file types. If your format isn't listed, please open an issue on our GitHub repository with details about the file type and your use case.

Why are PDFs processed on the server?

PDF text extraction requires specialized libraries that are too large to run in browsers efficiently. We use server-side processing for PDFs, DOCX, XLSX, and PPTX to maintain fast performance while ensuring accurate text extraction.

What if my file type isn't supported?

If it's a text-based file (can be opened in a text editor), you can rename it to .txt and upload it. For binary formats not yet supported, please request support on GitHub or use a conversion tool first.
