Why are basic PDF & signature tools still locked behind $20/month paywalls?

Hey Product Hunt community! 👋

A common frustration I kept hearing from freelancers, small business owners, and job seekers is how annoying it is to put a handwritten signature onto a contract, PDF, or Word document.

Usually, taking a photo with your phone leaves an ugly white rectangular box that covers the text underneath. Most solutions online either:

1. Require expensive software like Photoshop or Adobe Acrobat ($20+/mo)

2. Make you sign up or watermark your download

3. Upload your personal signature image to their cloud servers (a big privacy risk!)

To fix this, I built a 100% free tool:

How it works:

• Snap a quick photo of your handwritten signature on paper.

• It automatically extracts the ink strokes and turns the paper completely transparent.

• Auto-tightens the crop box flush against the letters (no dead space on top or bottom).

• Lets you change ink color to professional document blue or black.

• 100% Client-Side Privacy: All image processing runs locally in your browser via HTML5 Canvas. Your signature NEVER touches any server.

I'd love to get your thoughts:

1. How does the ink extraction and crop flow feel on your device?

2. What other everyday micro-tools do you wish existed online for free without signups or paywalls?

Appreciate any honest feedback!
