Free online tools that respect your privacy
SimplyToolbox is a growing collection of more than 90 free online tools that run entirely in your web browser. Instead of installing separate apps or uploading your files to a stranger's server, you can compress an image, merge a few PDFs, convert a video to a GIF, format messy JSON, generate a QR code, pick a colour or count the words in an essay — all on a single site, with nothing to download and no account to create. Most tools use modern browser technology such as the Canvas API and WebAssembly, which means your photos, documents and text are processed locally on your own device and never leave it.
The toolbox is organised into fifteen categories so you can find what you need quickly: image and video editing, PDF and audio utilities, developer helpers, text and calculator tools, colour and CSS generators, QR code, network, SEO, AI, productivity and fun tools. Every page explains what the tool does and how to use it, and our blog shares practical, jargon-free guides on getting the most out of them.
Everything here is genuinely free — no trials, watermarks or hidden limits — and designed to load fast and work on any device. Bookmark the tools you reach for most, and check back as we add new ones.
