About WebToolz

Small tools, no strings attached

WebToolz is a free collection of twenty-five everyday utilities that run entirely inside your web browser. No account, no upload, no queue.

Why we built it

Most of the jobs that interrupt a working day are tiny. Merge three PDFs. Shrink a photo so it fits an upload limit. Work out how many days until a deadline. Generate a password that is not your dog's name with a number after it.

Finding a tool for those five-minute jobs online usually costs more than five minutes. You land on a page wrapped in adverts, upload a file to a server you know nothing about, wait in a queue, hit a daily limit, and get asked for an email address before you can download the result. For a document you could have processed on your own laptop in under a second.

WebToolz is the version of that experience we wanted for ourselves: open the page, do the thing, close the tab.

How the tools actually work

Every tool on this site is written in plain HTML, CSS and JavaScript, and all of the processing happens in your browser using standard web platform features:

  • Files are opened with the browser's File and FileReader APIs — the same mechanism that lets you preview a photo before attaching it to an email.
  • Images are decoded, resized, cropped and re-encoded on an HTML <canvas> element.
  • PDFs are read and rewritten with bundled open-source libraries that run as JavaScript on this page.
  • Random values — for passwords, coin flips and the spinner — come from crypto.getRandomValues(), the browser's cryptographic random number generator.

Because the work happens locally, there is no upload endpoint on this site. A file you drop into the PDF merger is read into your computer's memory, combined, and handed straight back to you as a download. It never travels across the network, which is also why the tools keep working after you lose your connection.

What we offer

The toolbox is grouped into six categories:

  • Text & Generators — Lorem Ipsum, passwords, QR codes and favicons.
  • Converters — units, Roman numerals, image formats and Base64.
  • Calculators — age, BMI, loan EMI, percentages, date differences and countdowns.
  • Image Tools — compressing, resizing and cropping.
  • PDF Tools — merge, split, compress, watermark, images-to-PDF and passwords.
  • Utilities & Fun — a stopwatch and Pomodoro clock, a typing test, and a decision spinner.

New tools get added when enough people ask for the same thing. If something is missing, tell us.

What we do not do

  • We do not ask you to create an account.
  • We do not store, log or transmit the contents of the files you process.
  • We do not put a watermark on your output, or cap how many times a day you can use a tool.
  • We do not sell data, because we do not collect any to sell.

The one thing the site remembers is whether you prefer light or dark mode, and that preference stays in your own browser. Our privacy policy sets this out in full.

Honest limitations

Running everything client-side has trade-offs, and we would rather name them than pretend otherwise. Very large files are limited by your device's memory rather than by a server farm. Rasterised PDF compression trades searchable text for a smaller file. Calculators are built for everyday use, not as a substitute for professional financial, medical or legal advice — the disclaimer covers this.
