Hey Product Hunt! 👋 I'm Ugur, the solo maker behind ToolCrisp. The problem: every simple file task — converting a PNG, cleaning a CSV, formatting JSON sends you to a site that uploads your files to unknown servers, asks you to sign up, or blocks you after 5 free conversions. I kept hitting this wall, so I built the alternative I wanted to use. ToolCrisp runs everything in your browser. When you drop a file, JavaScript and the Canvas API process it on your device. No server ever sees your data. What's inside: 🖼️ 30+ image tools (convert, resize, compress, crop, watermark) 📄 PDF tools (merge, split, rotate, remove pages) 📝 10+ text tools (word count, regex tester, case converter) 🔄 15+ converters (JSON, CSV, Base64, URL encode, Markdown) 📺 Subtitle tools (SRT ↔ VTT, time shift, cleaner) 🎨 Color tools (HEX ↔ RGB ↔ HSL, palette generator) 🔒 Safe link checker (scans URLs against 4 security databases) 📱 Social media presets (YouTube, Instagram, Facebook, X) It's 100% free no premium tier, no paywall, no "upgrade to unlock." I built this for people who work with files daily and just want to get things done. I'll be here all day. What file task annoys you the most? I'd love the PH community to help shape the roadmap
