About UtilsDock
UtilsDock is a growing set of free online tools that run entirely in your browser. Your files and text stay on your device.
What UtilsDock is
UtilsDock is a collection of small, focused tools for everyday jobs: compressing an image to an exact size, merging PDFs, converting units, cleaning text, generating QR codes and many more. Each tool has its own page, in English and in Spanish, with an explanation of what it does, how to use it and what its limits are.
Why it runs in your browser
Most online tools ask you to upload your file to a server, which means trusting a stranger with your ID photo, contract or private document. UtilsDock takes a different approach: the code that does the work is downloaded to your device and runs there, like an installed program. The file is never sent anywhere, so there is no copy to leak, no upload to wait for, and no need for an account. After your first visit many tools keep working even without an internet connection.
How we choose and check tools
- Real problems first. We start from things people actually need to do, such as fitting a photo under 100 KB for an online form, and build the tool that solves them.
- Honest limits. Working in the browser has ceilings, such as memory on old phones. We write them on each page before you start, not after something fails.
- Tested with real files. Every tool is tested with real images, documents and data, on desktop and mobile browsers, and checked for accessibility.
- Worked-out results. Calculators show the formula and the steps, and the examples on our pages are calculated, not copied.
How it is funded
The tools are free and need no account. To cover the costs of running the site, UtilsDock may show advertising on some pages, always clearly separated from the tools and never inside the results. If ads are shown, they follow the consent rules that apply where you live. We do not sell your data, because we do not have it: your files and text never reach us.
Privacy and cookies
Because the tools run locally, we do not collect the content you process. The site itself may use basic technical storage, for example to remember a language or your recent tools, and may use analytics or advertising cookies only with your consent. The details are in the privacy policy, the legal notice and the cookie policy linked in the footer.
Corrections and contact
If a tool gives a result you think is wrong, a page is unclear, or you need a tool that does not exist yet, tell us at hola@utilsdock.com. We read every message, correct mistakes and use requests to decide what to build next. Financial, tax and legal calculators are meant as aids: check the figures against official sources before relying on them for filings or contracts.
