What Quezlo is
Quezlo is an independently run collection of 127 everyday web tools, grouped into ten categories. Each one is built to do a single job properly rather than to act as a free sample of something paid — there is no trial, no locked feature and no daily limit on any of them.
How it works
Every calculation on this site happens inside your browser using JavaScript. When you paste an essay into the word counter, encode your phone number into a QR code, or check whether two colours have enough contrast for body text, that work is done on your device. Nothing is transmitted to a server and nothing is stored anywhere we can read.
That has a consequence worth saying plainly: because no server does the work, there is no server bill to recover. This is why every tool is free with no trial period, no feature locks and no daily limit.
It also sets the boundary of what this site can offer. Anything that needs a server — hosting a file behind a QR code, counting how many people scanned it, saving your palettes to an account — sits outside what Quezlo does, and those are exactly the features other sites charge for.
What is here
Twenty-seven calculators, from mortgage and loan repayments to BMI, tips and unit conversion. Twenty-five maths tools covering percentages, fractions, statistics and equation solving. Twenty-three text and developer tools — word counting, JSON formatting, Base64, hashing, diff comparison and more.
Thirteen image tools, including an AI background remover that runs the model inside your browser. Eleven design tools for colour palettes, gradients, shadows and contrast checking. Nine PDF tools for merging, splitting, rotating, converting and generating invoices. Seven typing tests and games, seven health calculators, four QR and barcode tools, and one AI prompt builder.
Every one of them is listed on the homepage, searchable by name or by what you are trying to do.
How it pays for itself
Running Quezlo costs very little, because the tools do their work in your browser rather than on a server we have to rent. What it does cost is time — each tool is written, tested and documented by hand.
The site carries no paywall and no sign-in wall, and it never will. There is a voluntary support page for anyone who finds the tools useful and wants to help, and the site may carry display advertising in future. Neither will ever gate a tool behind a payment.
Who makes this
Quezlo is built and maintained by Muhammad Ishfaq, a creative director and multimedia designer based in Buner, Pakistan. His day job is brand identity, packaging and social media design — work that began in Karachi in 2016 and has since run through agency and in-house roles, including a spell as managing director of the creative division at a Malaysian group. His portfolio is at muhammadishfaq.netlify.app.
That background is why the tools here look the way they do. Most of them started as something needed mid-project: a contrast checker to prove a brand palette was actually readable, a background remover for product shots, an image resizer for a client's social feed, a PDF merger for sending artwork to a printer. Paying a monthly subscription for each of those, or uploading client work to a stranger's server, were both bad answers — so they got built to run in the browser instead, and left free for anyone doing the same kind of work.
Nothing goes live untested, and the testing is not done alone. Sayed Abas — a BS Information Technology graduate who teaches computer science and IT, and coordinates academic operations, at Government Degree College Daggar in Buner — works through new tools before they ship. He is a NAVTTC-certified UI/UX designer with a front-end background in HTML, CSS and Bootstrap, which means the feedback tends to be specific: a control that behaves oddly on a phone, a result that looks wrong for a particular input, a layout that breaks at a size nobody thought to check.
A good deal of what is on the site now exists because someone ran a tool on their own device, with their own files, and said the answer looked wrong. That is also why every tool page carries a report link — the same loop, opened up to anyone using the site.
