Aura File

The Core Problem: Trusting the Cloud

For the last decade, the standard model for web utility tools has been the same: you have a file you need to convert or compress, so you upload it to a server. That server processes the file, and then you download the result.

This model creates a massive point of failure. It forces you to hand over sensitive financial documents, legal contracts, and personal photos to unknown servers. As developers, we realized there is no longer any technical justification for this risk.

Client-Side Processing (The AuraFile Answer)

AuraFile completely reverses the traditional model. Instead of sending your files to our software, we send our software to your files. We utilize modern browser APIs and WebAssembly (WASM) to run complex operations—like PDF merging, AI background removal, and advanced image compression—directly using your device's CPU and memory.

How It Works Technically

1. No Network Transmission

When you drop a file into an AuraFile tool, the file is loaded into your browser's local memory via the HTML5 File API. It never touches a network request payload. If you open your browser's network tab while compressing an image, you will see exactly zero bytes of your file being transferred.

2. WebAssembly Execution

For heavy tasks like removing backgrounds, we download a small, isolated WebAssembly module (and a local AI model) to your browser cache on your first visit. Your browser then executes this code locally. WebAssembly runs in a secure sandbox, offering near-native performance without any required backend infrastructure.

3. Ephemeral Memory

Processed files exist only in your RAM as a Blob URL (e.g., blob:https://aurafile.net/...). The moment you close the tab or refresh the page, the browser's garbage collector permanently wipes the file from memory. We literally have no servers capable of saving your data even if we wanted to.

The Bottom Line

We cannot see your files.We do not have a database attached to the file processing logic. We do not log what you upload.
We cannot be breached for user files.Hackers cannot steal what we do not possess. Our server infrastructure strictly serves static HTML, CSS, and JS files.
It works entirely offline.Because the logic runs locally, once the page loads, you can disconnect your WiFi and the tools will still function perfectly.
