Our Privacy Promise

FileMuncher is built on a fundamentally different architecture than traditional online file tools. Instead of sending your files to a cloud server for processing, we ship the processing software to your browser.

How it works: We use WebAssembly (Wasm) — a binary instruction format that runs in all modern browsers at near-native performance. The same PDF manipulation libraries, image codecs, and video processing engines that desktop apps use are compiled to WebAssembly and executed locally in your browser tab.

• PDF tools use pdf-lib and pdfjs-dist — both run entirely client-side
• Image tools use the browser's native Canvas API and browser-image-compression
• AI Background Removal uses @xenova/transformers — machine learning models that run locally via WebAssembly, requiring no cloud API
• Video & Audio tools use FFmpeg compiled to WebAssembly — the industry-standard media processing engine, running in your browser

The first time you use a video or audio tool, your browser downloads the FFmpeg WebAssembly binary (~30MB). This binary is then cached locally so subsequent uses are instant — even offline.

We believe in being transparent. Here's exactly what FileMuncher collects:

• Account email and name (only if you create an account via Google or GitHub OAuth)
• Tool usage counts — which tools you use and how many times per day. This is used to enforce free-tier limits and improve the service. We track counts, not file contents.
• Payment data — handled entirely by our payment providers (Stripe, Paddle, LemonSqueezy). We never see your card details.

We do not collect: Your file contents, file names, file sizes, or any metadata from the files you process.

Most online file tools work like this: you upload your file to their server, their server processes it, and you download the result. Your file travels over the internet twice, is stored on their servers (even temporarily), and may appear in their logs.

FileMuncher works differently: the processing software is downloaded to your browser once (and cached), and your file never moves. This means:

• No data breach risk — your files can't be stolen from a server because they're never on one
• No retention policies to worry about — nothing to delete because nothing was stored
• Works in regulated industries — safe for legal, medical, and financial documents
• Faster for large files — no upload/download time; processing starts immediately

Does FileMuncher collect file metadata (name, size, type)?

No. File information never leaves your browser. We only track that a tool was used, not what file was processed.

Are my files safe when using the AI background remover?

Yes. The AI model (RMBG-1.4) is downloaded to your browser and runs locally via WebAssembly. Your images are processed entirely on your device — the AI never sees your photos on a remote server.

What happens when I close the browser tab?

The processed file exists only in your browser's memory. When you close the tab, it's gone. If you haven't downloaded your result, download it before closing.

Can FileMuncher see my files if I'm logged in?

No. Authentication identifies you for usage tracking and subscription management, but does not give FileMuncher any access to the files you process. The browser-based architecture ensures your files never reach our servers regardless of login status.
