Our Mission: Privacy by Architecture

Most online file converters follow an outdated server-upload pipeline: your files travel across the internet to a third-party server, wait in a remote queue, and are stored temporarily before you download the result. This exposes sensitive contracts, family photos, financial statements, and ID scans to potential leaks, data breaches, and cloud indexing.

ChameLeo flips this paradigm. By leveraging modern WebAssembly (WASM), Web Workers, and browser-native media APIs, the entire conversion engine runs directly on your computer or phone. Your files never touch our servers because there is no server upload step in our pipeline.

How ChameLeo Works Under the Hood

WebAssembly (WASM) Engine

We recompiled battle-tested open-source libraries like FFmpeg and Tesseract OCR into WebAssembly bytecode, executing natively in your browser sandbox with near-native speed.

Multi-Threaded Web Workers

Heavy processing tasks run in dedicated background threads, ensuring your browser interface remains snappy, smooth, and fully responsive throughout the conversion.

Zero-Cloud Architecture

Files are loaded into volatile browser RAM via local Blob URLs and garbage-collected immediately upon completion. Zero bytes of file content are transmitted over the network.

Core Values

Radical Privacy

We don't need a privacy disclaimer that promises 'we delete files after 1 hour'. With ChameLeo, we never have your files in the first place.

Instant Execution

No upload wait times and no server queue delays. Small and medium files convert in seconds directly using your local CPU hardware.

Universal Accessibility

No account creation, no subscriptions, no software downloads. Works on Chrome, Safari, Edge, Firefox across desktop, tablet, and mobile.

Frequently Asked Questions

How does ChameLeo differ from traditional cloud file converters?
Traditional online converters upload your files to remote servers where they are queued and temporarily stored on remote disks. ChameLeo operates on a zero-upload architecture: 100% of the conversion runs locally inside your browser via WebAssembly. Your files never travel across the internet, making ChameLeo the safest choice for confidential documents, contracts, and private media.
Which file formats and converter tools are supported on ChameLeo?
ChameLeo supports 200+ file extensions across 65+ dedicated tools, including PDF (PDF to Word, compress, merge), Video (MP4, AVI, MOV, WebM), Audio (MP3, WAV, FLAC, M4A), Image (JPG, PNG, WebP, HEIC, SVG), E-book (EPUB, MOBI), and developer archive utilities right inside your browser.
How can a web browser convert video, audio, and documents without a server?
Modern browsers support WebAssembly (WASM) and multi-threaded Web Workers, allowing battle-tested C/C++ libraries like FFmpeg and Tesseract OCR to execute natively inside your browser sandbox. Conversions run at near-native CPU speeds utilizing your local hardware.
Do I need to install software, create an account, or pay subscription fees?
No. ChameLeo is 100% free with no account registration, no subscriptions, and no software installation required. There are no daily conversion limits, artificial queue delays, or watermarks added to your converted files.
Does ChameLeo work on mobile devices (iPhone, Android) and all operating systems without installing apps?
Yes. ChameLeo is 100% compatible with all modern web browsers across iOS (Safari), Android (Chrome), macOS, Windows, and Linux. You can convert documents, images, audio, and video files directly in your mobile or desktop browser with zero software downloads and lossless output quality.
