All Free Online Tools

Every tool on this page works the same way: open it, use it, get your result — nothing to install, no account to create, and in almost every case, no file or data ever leaves your device. That's not a marketing line; it's the actual architecture. A PDF you merge, an image you upscale, or audio you transcribe is processed by code running in your own browser tab, using WebAssembly and the Canvas/Web Audio APIs rather than a server you'd have to trust. The tradeoff is honest too: very large files or AI-heavy operations (like image upscaling or transcription) lean on your device's own CPU or GPU, so performance varies with your hardware — there's no hidden server doing the heavy lifting for you. Use the category filters below to narrow down by what you're working on, or search by name if you already know what you need. New tools are added regularly, and the list below always reflects what's actually live, not a stale marketing page.
