160+ free online tools — PDF editor, compressor, converter, image tools, JSON formatter, QR generator and more. No signup, no upload, 100% private.
Love that everything runs client-side with no uploads, the privacy angle is genuinely thoughtful and rare. Curious though, how do you handle the heavier PDF jobs that usually need a server?
@arif1grq Thanks! That's exactly what we were aiming for. We intentionally built SJ Creation Tool Box with zero server-side file processing. Everything runs directly in your browser using libraries like pdf-lib, pdf.js, SheetJS, JSZip, and FFmpeg.wasm, so even larger PDF operations are processed locally on your device rather than uploaded to our servers.
The trade-off is that performance depends on your device's CPU and RAM instead of cloud servers, but in return your documents remain private—they never leave your device. For most everyday PDF tasks, modern browsers handle them surprisingly well.
