Frequently Asked Questions

Why is client-side conversion safer than online cloud APIs?

Many online conversion services upload your files to their cloud environments, opening potential data leak risks for confidential company files or user databases. Client-side conversion processes data within your device memory, guaranteeing absolute file privacy.

Are there limits to the size of files I can convert?

Since conversion occurs entirely in your browser window, the maximum file size is determined by your system's RAM and browser memory constraints. Most standard XML, JSON, or CSV data packages convert instantaneously.
