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.
Finally a clean toolbox that does not force an account or upload your files somewhere. The JSON formatter and PDF compressor worked nicely on the first try.
@aynur1896015 Thank you so much! 😊 That was exactly the goal behind SJ Creation Tool Box—no sign-ups, no file uploads, and no unnecessary friction. We're glad the JSON Formatter and PDF Compressor worked smoothly for you on the first try. If there's a tool you'd like to see added or improved, we'd love to hear your suggestions. Thanks for giving it a try! 🚀
