Free Online Tools That Run Entirely in Your Browser
iwanttools is a collection of 676+ free online tools that process everything locally on your device. Unlike most online tools, your files are never uploaded to a server. There is no signup, no watermark, no file size limit imposed by an upload queue, and no waiting for a server to respond. Every tool runs using JavaScript and WebAssembly directly in your browser.
The platform covers PDF tools for merging, splitting, compressing and converting documents; image tools for resizing, compressing, cropping and format conversion; text tools for counting, formatting and transforming content; developer tools for JSON, JWT, hashing and encoding; SEO tools for meta tags and structured data; and calculators for finance, health and everyday conversions.
Because processing happens on your own device, iwanttools is suitable for confidential material — contracts, medical records, financial statements, unreleased designs. Nothing leaves your computer, so there is no server-side copy to be retained, breached or subpoenaed. This is a fundamentally different security model from cloud-based tools that receive, process and temporarily store your files.
Tools work offline once the page has loaded, so you can continue working on a flight or with an unreliable connection. There are no accounts, no premium tiers, and no usage limits. Open a tool and start working immediately.
