When it comes to online file conversion, security is everything. Every day, millions of users upload personal or business files to online tools without knowing exactly what happens behind the scenes. At PlusConvert, we believe you shouldn’t have to trade privacy for convenience.
That’s why our converter uses a client-side architecture — a design that processes files directly in your browser instead of on remote servers. In this post, we’ll explore how this technology works, why it’s more secure than traditional server-based tools, and what it means for your privacy and peace of mind.
In simple terms, client-side processing means that all file conversions happen right inside your own browser — on your device — without your files ever being uploaded to a third-party server.
This is made possible thanks to modern web technologies like WebAssembly (WASM) and JavaScript APIs, which allow complex tasks such as image, audio, and document conversion to run locally with incredible speed and accuracy.
When you use PlusConvert, your files never leave your computer. Everything stays private, fast, and fully under your control.
Let’s compare how traditional converters handle your files versus how PlusConvert works:
| Feature | Server-Based Tools | PlusConvert (Client-Side) |
|---|---|---|
| Where Files Are Processed | On a remote server | Directly in your browser |
| File Upload Required | ✅ Yes | ❌ No |
| Risk of Data Exposure | High (files stored temporarily or logged) | None (files never leave your device) |
| Processing Speed | Depends on internet and server load | Instant and offline-capable |
| Privacy Control | Limited — you rely on third-party servers | Full — you control your data |
The difference is clear: client-side tools respect your privacy by design.
At PlusConvert, we built every part of our platform around one guiding principle: your data belongs to you. Here’s how we ensure that:
