Hey Product Hunt community! 👋 Like many of you, I got tired of hitting subscription paywalls on legacy conversion sites just to merge two PDFs or convert an image, only to find my document stamped with a watermark or held behind a 15-minute fake "conversion queue" unless I paid $9/month. Even worse: most traditional tools upload your confidential contracts and private photos to third-party cloud servers. That’s why I built ToolSphere — a fast, private, 100% free suite of 205+ browser-native utilities. ⚡ What makes ToolSphere different? Zero Remote Upload: Most tools run client-side using WebAssembly right inside your browser memory. Your files never touch external servers. 100% Free Forever: No subscriptions, no credits, no daily quotas. Zero Watermarks & Zero Signup: Instant access with anonymous, pristine exports. Multi-Category Power: From PDF merging & OCR to Android 108dp Adaptive Icon generation, SVG optimization, and JSON formatters. We’d love to hear your feedback on which tools you use most and what we should build next!
