The collection spans PDF, image, text, developer, SEO and calculator tools, with a small set of AI helpers such as a PDF summarizer and text humanizer that require a server and are openly listed. It is available as a web app built on Next.js, a Windows Electron desktop app (v1.1.24) distributed via GitHub Releases, and a Flutter-based Android app on Google Play.", "body_md": "Hey devs! I want to show you **ToolsMonk** — a free suite of 250+ online tools built around one core principle: **your files are processed on your device whenever technically possible.**\n\n## \n  \n  \n  What's inside\n\n- \n**PDF tools** — edit, merge, split, compress, sign, OCR, and convert to/from Word / Excel / PowerPoint\n- \n**Image tools** — resize, convert, rotate, background remover, photo editor\n- \n**Text & developer tools** — JSON/CSV converters, regex tester, JWT decoder, markdown tools\n- \n**SEO tools** — keyword density checker, SERP snippet generator, meta tag tools\n- \n**Calculators & converters** — loan/EMI, depreciation, fuel economy, cooking conversions\n- \n**AI helpers** — AI PDF summarizer and AI text humanizer (the few tools that need a server are openly listed at toolsmonk.com/where-your-files-are-processed)\n\n## \n  \n  \n  Why \"on-device\" matters\n\nMost tools run 100% in the browser — no uploads, no account, no file-size anxiety. Privacy by architecture, not by policy. Merge a 200-page contract PDF and the bytes never leave your machine.\n\n## \n  \n  \n  Three ways to use it\n\n- \n**Web** :[toolsmonk.com](https://toolsmonk.com)\n- \n**Windows desktop app** : Electron-based installer (v1.1.24) distributed via GitHub Releases\n- \n**Android app** : built with Flutter, available on Google Play\n\nStack notes for the curious: Next.js (App Router) on the web, Electron for desktop, Flutter for Android. One codebase philosophy per platform, shared tool logic where it makes sense.\n\n## \n  \n  \n  Feedback wanted\n\nIf you get a chance to try it, I'd genuinely love feedback:\n\n1. Which tools do you actually reach for in your daily work?\n2. What's missing from your current toolkit that you wish existed as a no-signup web tool?\n\nThanks for reading! 🙏", "url": "https://wpnews.pro/news/show-dev-toolsmonk-250-free-online-tools-that-run-on-your-device", "canonical_source": "https://dev.to/toolsmonk/show-dev-toolsmonk-250-free-online-tools-that-run-on-your-device-1d5c", "published_at": "2026-10-10 07:03:29+00:00", "updated_at": "2026-10-10 07:10:33.060468+00:00", "lang": "en", "topics": ["ai-tools", "developer-tools"], "entities": ["ToolsMonk", "Next.js", "Electron", "Flutter", "GitHub", "Google Play"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/show-dev-toolsmonk-250-free-online-tools-that-run-on-your-device", "markdown": "https://wpnews.pro/news/show-dev-toolsmonk-250-free-online-tools-that-run-on-your-device.md", "text": "https://wpnews.pro/news/show-dev-toolsmonk-250-free-online-tools-that-run-on-your-device.txt", "jsonld": "https://wpnews.pro/news/show-dev-toolsmonk-250-free-online-tools-that-run-on-your-device.jsonld"}}
