Canva is a commonly used free option
What do you want to do with your poster? Will this be used as a meme or will it actually go to a printer or be displayed on a high-res screen? If it’s just a meme thing, any image creator AI will do. Most of them have free options.
If this will actually go to a printer, you’ll need high resolution images and would do well to design it in a vector format, SVG for open source software: Inkscape is free to install on computers, vector-ink is a thing for mobile and the web as well. Adobe Illustrator for the corporate expensive route. Big file sizes work better on a good computer so YMMV.
Do you see this ? I just want to decorate it and make it attractive so that I can circulate it on various social media apps.
What you need is help, not AI. If paying a designer is out of the question, look for the most design savvy person in your family, friends, or in your neighborhood. Maybe you can comp them a meal in exchange for making this look good.
You can use AI image generators to make background images. Just check the licenses if you’re okay to use their stuff in a commercial setting. AI is still largely dog shit at handling real text in images. That’s why I wouldn’t recommend going this route for you here. You have a lot of text.
Yeah, I don’t get people trying to make easy money but not give other people money for their work. Don’t get it. India has lots of capable designers.
Inkscape
You need to download it ?
It’s a piece of software which runs on your computer.
If you find a so-called “web app” which runs in your browser, two things may be happening: 1) Someone took the effort to port an open source app (like InkScape) to run in a browser 2) You are using someone’s hosted service and they steal your information as the fee.
There’s also the option of taking your file to one of your local print shop, where they make it into a poster and charge you some fee.
You either pay money or effort.
