I recommend you to try Retouch because it's a smart ai that can remove everything or your unwanted objecta with just a swipe of the image, it also is a very useful app that has 4.6 reviews you can even have free trial which you can have unlimited editing. You can even change your photo quality to 2K or 4K it will remove blur or add more pixels and resolution if you keep waiting until it exports. Oh and also I discovered that. It was so interesting because I wanted to experiment. And it was to remove the imgflip watermark and I gently erased it in a very easy way and boom. NO WATERMARK LIKE SEROUSLY ZERO EFFORT. SO EASY AND VERY USEFUL

yeah that was long so I hope it fully works leave a review to also help them improve the app. Yeah and I don't have to say about this but I made a whole American speech so I hope u can peacefully remove the watermark freely so peace ✌(◕‿-)✌
