General Questions

AZUtils is a free collection of fast, browser-based online tools for everyday tasks. It brings together image tools, text tools, developer tools and calculators in one place, so you can compress an image, format JSON, count words or work out a loan EMI without installing anything — useful tools, from A to Z.

Yes. Every tool on AZUtils is completely free to use, with no trials, no watermarks and no hidden charges. You can use them as often as you like.

No. AZUtils works without any registration. Just open the tool you need and start using it straight away — no account, email or login required.

Privacy Questions

For most AZUtils tools — including image compression, format conversion and our developer utilities — your files are processed entirely within your browser and are never uploaded to our servers. Your data stays on your device.

No. We do not sell your personal data. We collect as little information as possible and use it only to operate and improve the site. Full details are in our Privacy Policy.

We collect minimal, mostly anonymous information — such as aggregate usage statistics and standard technical data like browser type — to keep the site secure and to improve it. If you email us, we receive only what you choose to send.

Developer Tools

Our developer toolkit includes a JSON Formatter, a JSON Validator, a Base64 Encoder & Decoder and a JWT Decoder. They are built for everyday coding and debugging tasks and run directly in your browser.

Our JWT Decoder runs entirely in your browser, so the token is not sent to us. Even so, treat any token as sensitive — we recommend not pasting production secrets or live credentials into any online tool, including ours.

Yes. Because the work happens on your device, the JSON Formatter handles sizeable files comfortably. Very large files depend on your device's available memory, but typical API responses and config files format instantly.

Image Tools

You can compress JPG, PNG and WebP images, and convert between PNG and WebP. These cover the most common formats used on the web and in everyday work.

Our Image Compressor is tuned to cut file size significantly while keeping images looking sharp. Some compression is lossy by nature, so we recommend keeping a copy of your original file just in case.

No. Image compression and conversion happen locally in your browser, so your images are never uploaded to a server — nothing leaves your device.

Calculators

The EMI Calculator uses the standard EMI formula and produces accurate estimates from the loan amount, interest rate and tenure you enter. Actual figures from a lender may vary slightly due to processing fees, taxes and rounding.

Yes. The EMI Calculator works for any reducing-balance loan — home, car, personal or otherwise — as long as you know the principal, the interest rate and the tenure.

No. Our calculators are for general information and estimation only and do not constitute financial advice. Always confirm figures with your bank or a qualified professional before making decisions. See our Disclaimer for more.

Security Questions

Yes. AZUtils is served over a secure HTTPS connection, and because most tools run in your browser, your files and data stay on your device. We follow sensible security practices to keep the site safe.

We recommend against entering real passwords, private keys or production secrets into any online tool, including AZUtils. For highly sensitive credentials, use a trusted offline environment.

Yes. The entire site is served over HTTPS, which encrypts the connection between your browser and AZUtils.

Performance Questions

Our pages are lightweight and most tools process data directly on your device, so there is no waiting for files to upload and download. Results usually appear almost instantly.

There are no usage limits — use the tools as often as you like. Practical file-size limits depend mainly on your own device's memory, since processing happens locally.

For typical tasks, no — processing is quick and efficient. Only very large files or images may use noticeable memory for a moment while the tool does its work.

Browser Compatibility

AZUtils works on all modern browsers, including Chrome, Firefox, Safari and Edge, as well as their mobile versions. For the best experience, keep your browser up to date.

No. AZUtils works out of the box in your browser — there are no plugins, extensions or downloads to install.

The tools rely on JavaScript to process data in your browser, so JavaScript needs to be enabled for them to work. It is switched on by default in virtually all browsers.

Mobile Usage

Yes. AZUtils is built mobile-first and works smoothly on phones and tablets, so you can use any tool on the go.

There is no separate app to install — AZUtils runs in your mobile browser. You can add it to your home screen for quick, app-like access.

Yes. The same tools and features are available on mobile and desktop, with a responsive layout that adapts to your screen size.

Data Processing

Most tools process your data on the client side — that is, inside your own browser — rather than on our servers. The work happens locally and the results are shown straight back to you.

For browser-based tools, your files and text are not sent anywhere; they are processed on your device. Any tool that needs server processing is the clearly-marked exception rather than the rule.

Because most tools run entirely in your browser, many keep working even if your connection drops after the page has loaded. We do not offer a formal offline mode yet, so a stable connection is recommended.
