About Toolsvu
Toolsvu is a browser-based hub of 615 small, single-purpose tools across 15 categories, text formatters, image processors, PDF utilities, color tools, social media mockups, AI helpers, SEO utilities, and a few dozen oddly-specific things you'll only need once but desperately need when you do. The whole point: stop sending you to 15 different sites for 15 different one-line tasks.
How the processing works
Most tools run entirely in your browser using the standard web APIs, Canvas, Web Crypto, File API, Web Workers. Text formatting, encoders, color converters, regex testers, hash generators, password generators, none of these send a single byte anywhere. The heavier jobs (image compression, PDF manipulation, video transcoding, audio conversion) hand off to a small Express API running on a single VPS. We use Sharp for images, pdf-lib for PDFs, and FFmpeg for video and audio. Files are wiped within an hour of upload regardless of whether you downloaded the result or not.
What's free, and why
Everything. No accounts, no rate limits, no premium tier hiding the useful version of a tool behind a paywall. The site is funded by display advertising, the ad slots you see between sections, and that's the entire monetization. We don't track what you paste, upload, or generate; the only thing stored locally is your theme preference and recently-used tools, both in your browser's localStorage.
