About KhanTools — Free Browser-Based Online Tools

What is KhanTools?

KhanTools is a free collection of browser-based productivity tools for everyday tasks. Whether you need to crop an image, remove a background, merge PDF files, add a signature, annotate text, or just edit a document — we have you covered, and we do it all directly inside your browser.

That means no files ever leave your device. Nothing is uploaded to our servers. Everything happens locally, using modern JavaScript APIs and WebAssembly libraries running inside your browser tab.

Our Tools

Image Crop — Crop any photo to a custom size or aspect ratio. Supports JPEG, PNG, and WebP.
Background Remover — Remove image backgrounds instantly using AI, entirely in your browser.
PDF Merge — Combine multiple PDF files into a single document. Drag, drop, reorder, and download.
PDF Sign — Draw your signature and embed it into any PDF. No printing or scanning required.
PDF Text — Add custom text overlays to any page of a PDF document.
Text Editor — A full-featured rich text editor for formatting, writing, and exporting documents.

Why We Built This

Most online tools either require you to create an account, upload your files to a third-party server, or pay for basic features. We think that is wrong. Simple tools should be free, fast, and private.

KhanTools was built on the belief that your files are yours. We never see them, store them, or transmit them. Our tools are open, ad-supported (to keep the lights on), and always free to use.

Who Is Behind KhanTools?

KhanTools is built and maintained by a small independent team of developers who are passionate about building practical, privacy-first web applications. We are constantly adding new tools and improving the ones we have.
