Why client-side processing matters

Most DocFuse tools run entirely in your browser. Your files are processed locally using JavaScript and WebAssembly - nothing is uploaded to a server unless the tool explicitly requires it. That means faster results, no file size limits from a remote queue, and no risk of your documents sitting on someone else's infrastructure. PDF merge, split, rotate, sign, unlock, OCR, and every developer utility on this site work offline once the page loads.
