# Online Tool Store > Online Tool Store (onlinetoolstore.io) is a free directory of browser-based > tools — PDF, image, developer, finance, text, and many other utilities. > Every tool runs entirely client-side in JavaScript: files and input are > processed on the visitor's own device and are never uploaded to a server. > No account, sign-up, or payment is required for any tool. Content is available in English and 23 other locales. English is the default locale and is served without a locale prefix (e.g. `/tools/...`); other locales are served under their language code (e.g. `/fr/tools/...`). A machine-readable sitemap of every page is published at https://onlinetoolstore.io/sitemap-index.xml. ## Start here - [Homepage](https://onlinetoolstore.io/): what Online Tool Store is, top tool categories, and how the tools work - [All tools](https://onlinetoolstore.io/tools): the full, searchable directory of every live tool, grouped by category - [Blog / guides](https://onlinetoolstore.io/blogs): how-to articles and explainers related to the tools ## Tool categories (representative pages) - [Developer tools](https://onlinetoolstore.io/tools/category/developer): formatters, converters, generators, and debugging utilities - [Image tools](https://onlinetoolstore.io/tools/category/image): resize, compress, convert, and edit images client-side - [Text & writing tools](https://onlinetoolstore.io/tools/category/text-writing): word counters, case converters, and formatting helpers - [Finance calculators](https://onlinetoolstore.io/tools/category/finance-calculators): loan, investment, and budgeting calculators - [SEO & web tools](https://onlinetoolstore.io/tools/category/seo-web): schema generators, meta tag checkers, and technical SEO utilities - [Health & fitness](https://onlinetoolstore.io/tools/category/health-fitness): BMI, calorie, and other wellness calculators The full category list is linked from the [homepage](https://onlinetoolstore.io/) and the [all tools](https://onlinetoolstore.io/tools) page. ## Example tool pages - [HTML Code Editor](https://onlinetoolstore.io/tools/html-code-editor): HTML/CSS/JS editor with live preview and console - [QR Code Editor](https://onlinetoolstore.io/tools/qr-code-editor): generate and style a QR code, download as PNG - [Text Separator](https://onlinetoolstore.io/tools/text-separator): split and rejoin text by any delimiter - [Breadcrumb Schema Generator](https://onlinetoolstore.io/tools/breadcrumb-schema-generator): build schema.org BreadcrumbList JSON-LD ## Feeds - [Blog RSS feed](https://onlinetoolstore.io/rss.xml)
