About
LocalForge is developed and owned by Pentaframe .
Private file tools. Entirely on your device. We build for engineering quality, privacy-first development, modern web technologies, and lasting user trust.
Our principles
- Privacy first — files stay on the user’s device.
- Performance — fast loads, aggressive code splitting, on-demand engines.
- Compatibility — designed for major desktop and mobile browsers.
- Honesty — clear limits when a device cannot convert a file locally; never a cloud fallback that breaks the privacy promise.

How it Works
LocalForge is a static website with powerful client-side tools and conversion engines. There is no processing API and no file storage backend.
1. You open a converter page
Pages are pre-generated from a converter registry so discovery and SEO scale to hundreds or thousands of format combinations.
2. You select files in the browser
Files are loaded into local memory. We deliberately say “select” or “add” files — not “upload” — because nothing is sent to a server.
3. Engines run on your device
Conversion is orchestrated in the main thread and executed in a Web Worker when possible. Engines and WASM modules load on demand and can be cached by the Progressive Web App for offline reuse — engine assets only, never your documents.
4. You download the result
The output is produced as a local Blob. A temporary object URL lets you save the file. That URL is revoked after download.
Privacy
Privacy is not a feature of LocalForge — it is the product. Unlike traditional online file converters, we never upload your files to any server.
What never happens
- No conversion requests are sent to a backend.
- No user documents are stored.
- No file contents are transmitted.
- No hidden uploads.
- No server-side processing of your files.
What does happen
Cloudflare serves the static website assets (HTML, CSS, JavaScript, and conversion engines). When you select a file, it is read into your browser’s memory. Conversion uses your device’s CPU and memory. You download the result from a local object URL.
Network transparency
During a conversion, your browser’s network panel should show only static asset requests (scripts, styles, WASM/engine binaries) — never your document contents leaving the device.
Accounts & analytics
No account is required to convert files. If analytics are enabled in the future, they will be privacy-first page-view metrics only. We will never collect file names, file contents, or conversion payloads.
