I want to create some webapp for editing image with drag and drop (remove logo, and put an other one, editing the text in the image etc). I explain, I create communication poster, but some people don't really like, the slogan on the poster, or they want to add their logo on the poster, add their website etc. That's what I want to create for user, be able to modify this kind of things on a PDF editor online, re-save at PDF and download it, directly on my website. I don't know if something like that exist already. Have you some way to explore ?
Thanks guys
There are a couple of online tools that let you edit images..
Here's a relatively simple one that I found while Googling: https://www.picozu.com/editor/
If that one doesn't fit your needs try searches like "online graphics editing program", "online image editor", or "online drawing editor"
