About AzenHub

AzenHub started because we kept googling the same stupid things. "What's 21:9 in pixels?" "How many frames in a 3-minute video at 24fps?" "What's 36px in rems?" Every time, we'd land on some calculator website that had 14 banner ads, a pop-up newsletter signup, and a loading spinner that took longer than doing the math by hand.

So we built the alternative. A small collection of tools that load fast, do one thing well, and get out of the way.

What We Build

Right now, AzenHub has six live tools covering video production, web development, and everyday math. We pick each one based on whether it solves a problem we personally hit in our own work, and we test it against real workflows before publishing.

The Blog

We also publish blog posts about the science and math behind the tools. Some of them dig into clinical research (like why ovaries age faster than the rest of the body), others break down practical decisions (like which frame rate to actually use in 2026). Every post cites its sources. We're not making things up to hit word counts.

How We Keep It Free

Hosting costs money. Domains cost money. The hours we spend building this cost time. We cover those costs through Google AdSense ads that appear on most pages. We'd rather have fewer ads and more readers come back, so we try to keep the ad density reasonable.

You can opt out of personalized ads through your browser settings or our cookie preferences. The tools still work either way.

What We Don't Do

• We don't sell your data. Ever.
• We don't require accounts.
• We don't send marketing emails.
• We don't use aggressive pop-ups.
• We don't publish clickbait.
