Hey Product Hunt! 👋
I'm thrilled to introduce Toolhast—an in-browser productivity toolbox built around a simple principle: your private files should never leave your device.
Like many of you, I got tired of shady PDF and image converter websites that bombard you with spammy popups, force you to upload sensitive bank statements or contracts to unknown cloud servers, and hit you with paywalls after 2 conversions.
So I built Toolhast. It packs 80+ tools into a clean, lightweight web app:
🔒 100% Client-Side Privacy: PDF tools (merge, split, sign, redact), OCR, image editing, and code formatters run entirely inside your browser via WebAssembly. Zero server uploads.
⚡ Blazing Fast: No upload/download wait times—manipulate 100MB+ files instantly.
💻 Developer Suite: Code-to-image social snippet generator, JSON validator, Base64/UUID utilities, text diffing.
🌍 Global & Accessible: 18 international languages with dark/light mode and zero signup walls.
It is completely free to use. I'd love to hear your thoughts, feedback, and feature requests. What tool should we build next?
Thanks for your support! 🙌
