Hello Product Hunt! 👋 It’s been a personal frustration of mine for a long time: I just wanted to watermark 100 photos for a client or an Etsy listing, but every "free" online tool I found came with a catch. Either I had to wait 20 minutes for a slow upload, or I had to hand over my proprietary photos to a 3rd party server, or I hit a paywall after the 5th image. 🙄 So, I built Stampix — a bulk image editor that does all the heavy lifting directly on your machine. What makes it different? Unlike traditional tools, Stampix is 100% browser-based. It uses the Canvas API and WebAssembly to process images locally. This means: 🚀 Zero Uploads: No waiting for files to hit the cloud. It’s instant. 🛡️ 100% Private: Your source images never technically touch the internet. They stay on your device. 📦 3-in-1 Workflow: Watermark, resize, and convert to WebP in a single batch click. I’m incredibly excited to finally share this with the community. My goal was to create a "utility tool" that actually feels like a utility—no accounts, no data-mining, and no limits on batch size. I’d love for you to try it out at stampix.app and let me know: What other image processing features would help your workflow? (Background removal? Frames?) Are there any specific fonts you’d love to see added? I'll be here all day to answer your questions! Thanks for the support! ❤️
