Compress images, merge PDFs, convert video to GIF, generate Excel formulas, beautify screenshots, and transcribe audio — no uploads, no accounts, no tracking.\n\nEvery YuliusBox tool runs on your device using modern browser technology — WebAssembly, the Canvas API, and on-device AI models like Whisper. When you drop a file into a tool, it is processed by your own CPU and GPU; nothing is sent to a server, stored in a database, or logged. That means no queues, no file-size quotas imposed by server costs, and no privacy trade-offs — your tools even keep working offline once the page has loaded.\n\nFiles are processed on your device and never sent to a server.\n\nEvery tool works instantly. No accounts, no email walls.\n\nAll core tools are free to use, with no watermarks.", "url": "https://wpnews.pro/news/show-hn-yuliusbox-26-free-tools-that-run-in-the-browser", "canonical_source": "https://www.yuliusbox.com", "published_at": "2026-09-29 11:48:35+00:00", "updated_at": "2026-09-29 12:18:31.034489+00:00", "lang": "en", "topics": ["ai-tools", "developer-tools"], "entities": ["YuliusBox", "Whisper", "WebAssembly", "Canvas API"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/show-hn-yuliusbox-26-free-tools-that-run-in-the-browser", "markdown": "https://wpnews.pro/news/show-hn-yuliusbox-26-free-tools-that-run-in-the-browser.md", "text": "https://wpnews.pro/news/show-hn-yuliusbox-26-free-tools-that-run-in-the-browser.txt", "jsonld": "https://wpnews.pro/news/show-hn-yuliusbox-26-free-tools-that-run-in-the-browser.jsonld"}}
