Alona Tool – Free Online Tools

About Alona Tool

What it is, why it exists, and how it works

Alona Tool is a collection of free, browser-based utilities for everyday tasks: writing and editing documents, working with PDFs and images, cleaning up text, formatting code, generating QR codes and passwords, and running quick calculations. Alona Tool is an independently maintained web tools project.

The problem it tries to solve

Small jobs — merging two PDFs, resizing an image, checking a loan payment, formatting a block of JSON — often mean installing software, signing up for an account, or uploading a file to a site you know little about. Alona Tool puts these utilities in one place that you can open in a browser and use right away.

Our mission

To provide simple, accessible and useful online tools that work for as many people as possible, on any modern device, without making you create an account for basic tasks. We aim to keep each tool focused, explain what it does and what its limits are, and be straightforward about how your data is handled.

How it works

Many tools run client-side: your browser does the processing, using standard web technologies, so files and text you work with in those tools are not uploaded to an Alona Tool server. We do not operate a database for user files or tool inputs. Some tools save your work-in-progress (for example an unfinished document or presentation) in your own browser’s local storage so it is still there when you return; that data stays on your device and you can clear it from your browser settings. A small number of features use external services — for example, fetching a YouTube thumbnail, loading web fonts, or handing a summary to the WhatsApp, email or share app you choose — and the site may show Google AdSense advertising once it is enabled, which is served by Google rather than by us. The Privacy Policy explains each of them.
