Philosophy
Your browser in 2026 is a supercomputer. Most tools still pretend it's 2005.
A server that doesn't receive your files can't breach them. Our architecture makes leaks structurally impossible — not just policy-improbable. Your files stay in your RAM and nowhere else.
No upload. No queue. No round-trip. The moment you click, your CPU and GPU are on it. Modern browsers expose WebAssembly, WebGPU, and multi-threading — power that most tools waste routing through a server rack.
Server bills are why free tools become paid tools. When compute is your device, our infrastructure cost is near zero. That's why every tool here is free — not as a trial, not with a cap. Just free.
Open the tool, disconnect your WiFi, keep working. Because there's no server to phone home to, an internet connection is optional after the first load. Your workflow doesn't stop when connectivity does.
The same machine running your browser can process images, merge PDFs, build resumes, and strip metadata — at speeds that rival native apps. Browser APIs caught up years ago. The tools just hadn't.
No email address, no password, no session token, no subscription ID. Without accounts there's nothing to steal and nothing to forget. You open the URL, you use the tool, you're done.
