Hi Fazier community! 👋 I’m super excited to share ZeroKB with you all today. 💡 How the idea started: Like many of you, I faced the classic everyday frustration—trying to upload a photo, signature, or document for an online application or portal, only to get hit with errors like "File size must be under 50KB" or "File is too large." When I looked for quick solutions, most existing websites were cluttered with annoying ads, forced you to create accounts, or put basic tools behind expensive paywalls. 🚀 What ZeroKB does: I built ZeroKB to be a fast, clean, and 100% free browser-based utility suite. It lets you compress, resize, merge, and convert PDFs and images instantly without installing any software, creating an account, or dealing with watermarks. Key tools available right now: - Precision Image & Photo Resizer (exact KB targets) - PDF Compressor & Merger - Multi-format document converters I would love for you to try it out, test the compression speed, and share your honest feedback. What other file utility tools do you find yourself needing the most in your daily workflow? Looking forward to your thoughts and happy to answer any questions! Cheers! 🚀
