Your Data Never Leaves Your Device
We use client-side WebAssembly to process your files securely within your own browser. No uploads. No cloud storage. No risk.
The "Zero-Upload" Promise
Traditional online tools work by uploading your file to a remote server, processing it there, and sending it back to you. This creates a massive security vulnerability: you lose control of your data.
ToolMint is different. We have re-engineered standard processing libraries (like FFMPEG, ImageMagick, and PDF-Lib) to run directly inside your web browser using WebAssembly (Wasm).
When you select a file on ToolMint:
- It remains in your device's RAM.
- It is processed by your device's CPU.
- The result is saved directly to your Downloads folder.
At no point does the file travel over the internet to our servers.
No Server Storage
Since we don't have a backend to receive files, we literally cannot store your data even if we wanted to. We have no database for user files.
Ephemeral Lifecycle
Your file data exists in the browser memory only for as long as the tab is open. Once you close the tab or refresh, the data is instantly wiped from RAM.
Sandboxed Execution
All code runs in a sandboxed environment within your browser. It cannot access other files on your computer or communicate with external domains without your explicit action.
Technical Security Measures
HTTPS / TLS 1.3
While files aren't uploaded, the website code itself is delivered via a secure, encrypted connection (HTTPS) using strict transport security protocols.
WebAssembly (Wasm)
Critical processing logic is compiled to Wasm, which is memory-safe and runs at near-native speed without the security risks of historic plugins like Flash or Java.
Open Source Core
Our tools are built on top of battle-tested open-source libraries. This transparency allows the security community to audit the core logic we use.
No Analytics on Files
Our analytics are strictly limited to page views and button clicks. We do not (and cannot) inspect the contents, names, or metadata of the files you process.
