Hey Product Hunt community! 👋 I'm Jay, the creator of StarSign16. Like many of you, I was tired of hitting paywalls, forced sign-ups, and annoying watermark restrictions just to remove an image background or format some text. On top of that, uploading personal assets to unknown cloud servers always felt risky. So, I built StarSign16 with a strict philosophy: 1. 100% Free & Unlimited: No accounts, no subscriptions, no paywalls. 2. 100% On-Device & Private: AI background removal and file conversions run entirely in your local browser memory (zero server storage/transmission). 3. Zero-Barrier UX: Clean dark-mode interface designed to get the job done in under 3 seconds. Currently, it features 16 single-purpose tools (AI Background Remover, Image Converters, Markdown Live Editors, Regex Testers, and more). I’d love to hear your feedback, feature requests, or ideas for the next tool! Thank you for the support! 🚀
