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.
Who is behind it
Tooletto is built and run by AdvisorLB Development, a software studio in Beirut, Lebanon that builds custom software, web platforms and AI products, and is maintained by Mhmd Husseini. It is not a marketplace, an agency front or a content farm: the tools exist because we needed them ourselves and were tired of upload queues, watermarks and sign-up walls for two-minute jobs.
Studio: Badaro, near Byblos Bank, Beirut, Lebanon. Hours: Monday to Friday, 9:00 to 18:00 Beirut time. Phone: +961 70 706 541. Email: contact@advisorlb.com.
The site is supported by advertising rather than by selling user data — there is no user data to sell, since files never leave your device. What we do and do not collect is spelled out in the privacy policy, and the contact page reaches a person, not a ticket queue.
Editorial standards
Every tool page and blog post is written for this site, checked against the tool it describes, and corrected when a reader points out a mistake. Where a page states a number — a compression ratio, a password entropy, an interest calculation — the related tool lets you reproduce it yourself.
