About ToolBox World

Our mission

Simple jobs shouldn’t require installing software, creating an account or handing your files to a stranger’s server. Whether you need to shrink a photo for an email, join two PDFs for a job application or check the word count of an essay, we want the answer to be one click away — on any device, anywhere in the world.

What makes us different

• Privacy first. Our image, PDF and text tools run inside your browser. Your files are processed on your own device and are never uploaded to us.
• Genuinely free. No sign-up, no usage caps and no watermarks. The site is supported by unobtrusive advertising.
• Carefully crafted. Every tool has clear instructions, validation that explains what went wrong, and explanations of how it works.
• Accessible. We follow accessibility best practices — keyboard navigation, screen-reader labels, sufficient contrast and a dark mode.

What you’ll find here

Our toolbox is organised into 5 categories:

• Image Tools — Compress, resize and convert JPG, PNG and WebP images right in your browser.
• Text Tools — Count words, change letter case, clean whitespace and tidy up lists.
• Developer Tools — Format and validate JSON, encode Base64, URL and HTML, and generate UUIDs.
• Calculators — Percentages, age, BMI and discounts calculated instantly and accurately.
• PDF Tools — Merge, split and convert PDF files without uploading them anywhere.

How we are funded

To keep every tool free, ToolBox World may display advertising provided by Google AdSense. Ads are clearly labelled and are kept away from tool controls so they never get in the way of your work. You can read more in our Privacy Policy and Cookie Policy.
