Every tool on FreeToolsLand is built and checked by Mohit, who runs the site. This page explains what “tested” means here, what stays on your device, and how mistakes get fixed, so you can decide how much to trust a tool before you use it.
What every tool is checked for
- The result, not just the screen. We open the file the tool gives you. A rotated image must be rotated in the download, text added to a photo must be in the saved picture, and a barcode must scan with a phone.
- Desktop and phone. Each tool is tested on a desktop browser at 1350 pixels wide and on a phone-sized screen at 390 pixels, including touch dragging and file pickers.
- Wrong and awkward input. Empty boxes, invalid colours, broken JSON, huge files and text in other languages should give a clear message, never a silent failure.
- Numbers checked by hand. Calculator results, contrast ratios and barcode check digits are compared with the published formulas.
- Speed. Pages should load quickly on a phone connection, and tools should respond in under a second for normal files.
A real example: the November 2026 review
In early November 2026 every tool on the site went through a full quality review. It found 30 bugs, and all of them were fixed and re-tested on desktop and phone. Some of them:
- The Rotate and Flip tool showed the rotation on screen but downloaded the original image.
- The Text Overlay tool could save a picture without the text, and at a smaller size than the original.
- The CSS Box Shadow generator ignored an invalid colour without telling you.
- The password generator’s “pronounceable” option used a weaker random source; it now uses the browser’s cryptographic generator like the rest of the tool.
- The colour contrast checker’s RGB and HSL boxes looked editable but did nothing; they now update the result.
What stays on your device
Almost every tool runs entirely in your browser: images, text, passwords, JSON and colours are processed on your own device and are never uploaded to our server. You can check this by loading a tool, turning off your internet connection and using it.
The exceptions are tools that need information from another website. The video downloaders send the link you paste to look up the public video, and the Currency Converter fetches current exchange rates. They never ask for your logins, and we do not keep the links.
How the guides are written
Guides explain a task step by step and link to the tool that does it. Facts that change, such as prices, platform rules and size limits, are checked against the official source and dated in the article, and guides are updated when the rules change.
Found a problem?
If a tool gives a wrong result or does not work on your device, please tell us on the Contact page with the tool name, your browser and what you entered. Bug reports are fixed first, before new tools are added. You can read more about who runs the site on the About page.
