TL3 Tools is the free, browser-based utility collection published by TL3 Communications, a web development and communications company based in Vancouver, British Columbia. We build calculators, converters, and text processors for people who need a quick answer without installing an app or creating an account.
The same small team conceives, builds, documents, and reviews every tool on this site. The company operates out of 218-401 W Georgia St, Vancouver, BC V6B 5A1, and the people below are the ones doing the work.
Sarah is the lead writer and owns the calculator collection. She researches each formula, works through examples with real numbers, and writes the guides that walk readers through everyday math — percentages, tips, EMI, and unit conversions. Her bylines include the percentage guide and the social-media character-count post on the blog.
Alex builds the tools. He writes the JavaScript that powers each utility and documents how the encoding, parsing, and hashing algorithms behave. He also covers web security on the blog, including the password security guide, the Base64 primer, and the regex tutorial for beginners.
Jane is the editor. She reviews every page before it ships, checks the math and the claims, and keeps the copy accurate and readable. Her pass catches mismatches between what a tool does and what its documentation says before either reaches the live site.
Each tool starts with a short spec that names the exact formula or algorithm it will run. Sarah checks that math against published references and hand-computed examples, Alex implements it in plain JavaScript, and Jane reads the finished page back against the spec.
Before a tool goes live, we verify it against known inputs. The percentage calculator is checked with a value like 23% of 480, date and time tools are checked against spans we have worked out by hand, and every encoder is tested with strings whose output is known in advance. We also run the pages in Chrome, Safari, and Firefox and watch how they behave with very long input or with JavaScript switched off.
Building client-side is a constraint we choose, not a shortcut. Because every calculation runs in your browser, there is no server job to scale, no account system to maintain, and no reason to ask for your email address. Results are produced on your device and gone when you close the tab.
All processing happens client-side using JavaScript. The text, numbers, files, or colors you enter are handled locally by the page itself and are never uploaded to TL3 Communications or to any third party.
This page does load Google tags for analytics and advertising, which is why a consent banner appears on your first visit. That consent choice is stored in your browser, and your tool inputs stay separate from the analytics data. The privacy policy describes what Google receives in plain terms.
Bug reports, questions, and tool requests are welcome. The fastest path is the contact page, which forwards your message through a form, or you can email support@tl3.com directly.
