Building a Real Free GIF Generator — No Logins, No Watermarks, No Tricks

#javascript #html #tooling

Every time I tried to make a simple animated GIF online, I ended up in the same frustrating loop. Either the tool wanted me to create an account, or it uploaded all my images to a remote server, or worse — it added a massive watermark right on top of the animation. Some even claimed to be “free,” but after 10 minutes of work, a big “Upgrade to Premium” message would pop up.

So I decided to do something different.

Why I Built This Tool

I just wanted something simple, private, and truly free.
A tool where you could drop your images, set the transitions, and export the GIF — all directly from your browser. No signups. No hidden uploads. No nonsense.

That’s how this GIF Generator was born. It’s a lightweight web app that uses your own browser’s power (thanks to JavaScript and HTML5 Canvas) to create the animation. Nothing ever leaves your device — all the magic happens locally.

How It Works

The concept is simple:

You add your images (as many as you like).
You can choose transition effects between frames — smooth fades, slides, and more.
You set the GIF width, height, and frame duration.
Then just hit Generate — and within seconds, you’ll have your animation ready to download.

There’s no watermark, no compression tricks, and no need for an internet connection after loading the page (everything runs in your browser).

Privacy by Design

I never liked tools that secretly upload your media “for processing.” That’s why this one doesn’t even touch a server.
When you load the site, the entire app runs as a self-contained script — your images stay on your computer. Even if you disconnect from the internet, it will still work perfectly (as long as the page is loaded).

That means:
