About LIVETOOLSLAB

LIVETOOLSLAB is a website of free online tools that run in your browser: image and PDF utilities, on-page SEO helpers, marketing calculators, writing counters and everyday calculators.

Why we built it

Many simple jobs (shrinking a photo, combining scans into a PDF, checking a ROAS target) send people to sites that ask for an account, add watermarks, or upload files to a server without saying so. We wanted small, focused tools that do one job well, explain the result, and keep files on the user’s own device.

How we build and check the tools

• Each tool is tested with normal, empty, invalid and extreme inputs, on mobile and desktop widths, before it’s published.
• Calculator pages show the formula and a worked example so results can be verified by hand.
• File tools use well-known open-source libraries (PDF.js, pdf-lib, jsPDF, JSZip and qrcode-generator), served from our own site.
• When a tool has a limitation, such as the PDF compressor removing selectable text, the page says so.

What we don’t do

We don’t publish fake reviews, ratings or user numbers, and we don’t promise results that no tool can guarantee, such as search rankings.
