HOW CLIENT-SIDE SANDBOXED CONVERSION WORKS

Transform your digital assets locally in 3 secure stages

01

Load Assets Locally

Drag, drop, or select your target documents, images, audio, or video files. Because we utilize high-performance modern browser environments and WebAssembly (Wasm) standards, your files are processed directly on your computer.

02

Instant Sandboxing

Your computer acts as an isolated sandbox environment. Our conversion engine runs locally via W3C web isolation specifications. This means 100% data privacy—your documents are never uploaded to remote external servers.

03

Secure Download

Once the local pipeline finishes, your newly converted document is immediately ready for download. This ensures zero latency, absolute compliance with corporate privacy guidelines, and no cloud interception risks.

FREQUENTLY ASKED QUESTIONS

Deep dive into local file conversion, technology benchmarks, and features

Is my file data secure with FilezyConvert?

Yes, absolutely. Unlike legacy online file converters that transmit your highly confidential PDFs, text files, and images to their external cloud servers, FilezyConvert processes everything directly on your browser using advanced client-side sandboxing. Your files never leave your device.

What file format combinations can I convert?

FilezyConvert provides extensive support for multiple digital formats, including document transformations like Word to PDF (DOCX to PDF), Excel spreadsheets, high-performance image compression (PNG, JPG, WebP), video-to-audio extraction (MP4 to MP3), and standard programming schemas (JSON, XML, YAML).

What is the advantage of using local WebAssembly pipelines?

WebAssembly (WASM) allows us to run high-performance compiled libraries (like FFmpeg and LibreOffice-like parsers) directly inside your web browser at near-native execution speeds. This removes network upload times entirely, enabling instantaneous conversions of large video and image files without internet bottlenecks.

How does the Premium subscription tier work?

While standard conversions are completely free for daily operations under strict size constraints (up to 10MB per file), upgrading to our premium subscription tier unlocks massive upload volumes (up to 500MB+), unlimited daily runs, priority SLA support, and advanced AI document, CV, and business proposal generators.

Are there developer APIs and webhooks available?

Yes. Under our Enterprise tier, developers can easily unlock local sandbox environment endpoints, configure automated workflow pipelines, integrate with corporate databases, and leverage custom API structures for bulk document rendering.

How do I design social cards with the Reposter Tools?

Our social reposter tools allow digital creators to generate high-fidelity, premium glassmorphism mockups of Instagram, Facebook, and X (Twitter) posts. These are entirely generated in-browser, letting you customize statistics, text alignment, and themes before saving them as high-definition image cards.
