About Utylo

Why we built Utylo

Most of the small tasks that slow down a working day — compressing a photo before emailing it, cleaning up a block of JSON, converting kilometres to miles, counting characters for a tweet — used to require desktop software or a carousel of sketchy websites plastered with intrusive ads, sign-up walls and hidden uploads. We built Utylo to collect those everyday utilities in one calm place that respects your time, your data and your attention.

Utylo is a free, ad-supported collection of 76 browser-based tools organised into 10 categories: image processing, text utilities, developer tools, SEO helpers, math and finance calculators, unit converters, date and time tools, content generators, social media helpers and privacy utilities. Every tool is designed to solve one specific problem well — nothing more.

How Utylo is different

1. Your files never leave your device

Almost every tool on Utylo runs entirely inside your browser using standard web APIs — Canvas for images, Web Crypto for hashing, JavaScript's Intl and Date APIs for time conversions, and so on. When you compress an image or format a JSON blob, the computation happens on your own CPU. Nothing is uploaded, stored, or even transmitted to our servers, because there is no server-side processing to transmit it to. You can open the browser's network inspector while using any tool and verify this yourself.

The only exceptions are tools that fundamentally require an external lookup — for example, the IP Address Lookup tool queries a public geolocation API because there is no way to geolocate an IP address without a database. Where this is the case, we say so on the tool page.

2. No sign-up, no paywall, no throttling

Every tool is free to use an unlimited number of times. We do not ask you to create an account, verify an email, watch a video ad, or wait in a queue. We do not keep a "Pro" tier in reserve that unlocks the useful features. If a tool exists on Utylo, it works — fully — without friction.

3. Built for durability

Utylo is a static site built on Next.js and deployed on a global CDN. Pages load in under a second on a typical connection, work offline after the first visit for most tools, and are designed to keep working even if our business situation changes. We deliberately avoid complex back-end dependencies so the site remains cheap and simple to maintain indefinitely.

4. Honest about advertising

Utylo is supported by display ads served through Google AdSense. Ads are how we pay for the domain, the CDN and the time it takes to keep the site maintained. We limit ads to two unobtrusive slots per page — a banner above the fold and a sidebar on wide screens — and we never disguise ads as tool output, search results, or navigation.

You can read exactly how advertising works on Utylo, what cookies are set and what data is shared, on our Privacy Policy page.

Our engineering principles

• Do one thing well. Every tool solves a single, clearly named problem. If it starts to grow a second purpose, we split it into a second tool.
• Default to client-side. If a problem can be solved in the browser, it will be. Server calls are a last resort.
• No dark patterns.No fake download buttons, no countdowns, no "your file will be deleted in 5 minutes — upgrade to save". You will never see a modal asking you to rate us.
• Accessible by default. Tools work with keyboard navigation, have meaningful labels, and scale to small screens.
• Document the edges. Every tool page explains the limits — what formats are supported, what happens to very large inputs, what the tool is not suitable for.

What Utylo is not

Utylo is not a replacement for professional software when the stakes are high. The Loan Calculator gives you a solid estimate, but your bank's actual amortisation schedule is the legal figure. The Privacy Policy Generator produces a reasonable starting document, but a lawyer who understands your specific jurisdiction should review anything you publish. The Hash Generator is great for checksums but is not a substitute for authenticated encryption.

We say this plainly on every tool that warrants it, and we recommend treating Utylo the way you would treat any free utility on the open web: useful, fast, and worth double-checking when it matters.

Who runs Utylo

Utylo is independently operated by a small group of web engineers who were tired of tool sites that treated visitors as an opportunity rather than a person with a problem. The site is not venture-backed, not owned by a larger marketing network, and not affiliated with any of the companies whose file formats or standards our tools work with.

We welcome feedback — especially bug reports and requests for tools that would fit the collection. You can reach us through the Contact page.
