Frequently Asked Questions

Absolutely. All file processing happens 100% in your browser using Web Workers and WebAssembly. Your files never leave your device — we have no server to upload them to. You can verify this by disconnecting from the internet and using any of our tools.
Since everything runs in your browser, the limit depends on your device's RAM. Most modern devices can handle files up to 500MB. For larger files, we use streaming and chunked processing to minimize memory usage. We'll warn you if a file might be too large for your device.
Yes, ConvertX is completely free with no hidden costs, no subscriptions, and no limits on the number of conversions. Since we don't have server costs (everything runs in your browser), we can afford to keep it free.
ConvertX works best in modern browsers like Chrome, Firefox, Edge, and Safari. Some features like video conversion require WebAssembly and SharedArrayBuffer support, which are available in all recent browser versions.
Yes! Most of our tools support batch processing. You can drag and drop multiple files at once, and they'll be processed in parallel using Web Workers for maximum speed. You can download all results as a single ZIP file.
We use FFmpeg compiled to WebAssembly (ffmpeg.wasm), which is the same powerful tool used by professionals, running entirely in your browser. The first time you use it, there's a one-time download of the WASM binary (~25MB), which is then cached by your browser.
