About Tooletto
Tooletto is a collection of 71 free online tools that run in your browser. There is no upload step, no queue, no watermark and no account requirement.
Why in-browser
The conventional way to build an online file tool is to upload the file, process it on a server, and send the result back. That design has three costs the user pays: they wait for two network transfers, they hit a file size limit that exists to protect the server, and they hand a private document to a stranger.
Modern browsers can do the work locally. Canvas handles image encoding, WebAssembly runs the same codecs desktop software uses, and Web Workers keep it all off the thread that draws the page. Processing starts the instant you drop a file, size limits are set by your own device, and the file never leaves it.
How it is built
Every tool is an independent module containing its own metadata, interface and processing logic. Pages are statically generated, so the tool you asked for arrives as finished HTML and only the interactive part is downloaded afterwards.
