Why I ask for tips

Hi, I'm Michael. Thank you for being here.

What it costs

I use the Porkbun renewal list price for the domain estimate above, checked October 17, 2026. GitHub Pages hosts the site at no charge.

What tips pay for

• Keeping the krzen domain renewed so your bookmarks keep working.
• Checking compression and fixing problems with image formats.
• Improving the page-speed tools alongside the compressor.

Tips unlock nothing, and everyone gets the same free tools whether they tip or not.

Prefer monthly, or want to support my open-source work too?

If you'd prefer to give monthly, you can tick 'Make this monthly' on Buy Me a Coffee and cancel at any time.

The use count on this site stays in your browser. I never see it.

PayPal shows my legal name, Michał Lip.

It is a tip, not a purchase, and you owe nothing for using the site.

Michael
