Hi Product Hunt! 👋 I built Signature Resizer out of personal frustration. Every time I had to fill out an official government or job application form, it asked for a signature with crazy constraints (like "exactly 400x150 pixels and under 50KB"). Doing this in heavy photo editors was annoying, and I didn't want to upload my actual legal signature to random servers online due to privacy concerns. So, I built a quick, 100% client-side browser tool to solve this. It lets you crop, resize to exact dimensions, and compress instantly. Because it uses native browser APIs, the image is processed locally and never leaves your device. It's completely free. I’d love your feedback and would be happy to answer any questions about the client-side implementation
