FileBox is built on a simple promise: your files and data stay yours, always.
Local Browser Processing & No File Uploads. All file operations — compressing, expanding, and converting — run entirely inside your browser using modern JavaScript APIs. Your files are never transmitted, uploaded, or sent to any external server. We have no infrastructure that receives your files, because we never need to. Everything stays on your device from start to finish.
No Personal Data Stored. We do not collect, store, or retain any personal information about you. No account is required to use FileBox, and no identifying data is associated with your session, device, or activity. Once you close the tab, nothing about your visit is remembered on our end.
No Tracking or Analytics Misuse. We do not profile, track, or sell your usage data to any third party. Any site-level analytics used are strictly limited to understanding general traffic patterns for performance improvement and are never linked to personal identity or file activity.
Your Privacy is Fully Respected. Privacy is not an afterthought — it is the foundation FileBox is built on. You are always in full control of your files and your data. We are committed to keeping it that way, with no exceptions, no hidden clauses, and no compromise.
FileBox is a product of BlackFish Creative, dedicated to building simple, privacy-focused tools that respect your data. We believe that file processing shouldn't require uploading your sensitive documents to unknown servers.
All our tools run entirely in your browser using modern JavaScript APIs. Your files stay on your device, and we never see, store, or access any of your data.
