Why aren't all (AI) tools like this? Simple and straightforward to use, without any annoying ads, subscription models or whatever. It's totally free without any artificial limits. Oh and btw, the upscaling itself produces great results and is pretty fast if the queue is not too long. Thank you for this handy tool, definitely deserves a donation!
This is amazing. Found from a Reddit post, I was using a different website that would only allow like 2 upscales a day. I make thumbnails for my very casual YouTube account and some pictures I use are low quality, I then use paint.... which also makes everything look blah. This tool is fantastic. I will be donating money to make sure it stays up, it is my new go to.
Easy to use and very useful for upscaling old digital artwork with very low resolutions by modern standards. Thumbs up! 👍
was on the edge of a cliff, staring into the emptiness of broken dreams, ready to give up on my POD idea after I discovered that all the "free" AI upscalers out there delivered nothing but pixelated lies & broken promises. My images were beautiful… but pitifully tiny.
Then—like a lone beacon cutting through an ocean of mediocrity—your project appeared. No paywall. No watermarks. No guilt traps like "please subscribe" just to have basic functions.... Just killer output. Awesome, gigantic, sharp images.
You didn’t just save my project—you brought it back to life from the ashes like a phoenix. Ill donate as soon as the first dime rolls in off these images, & Ill keep donating as long as I keep on using this beautiful sorcery.
Whoever you are, you have my eternal gratitude, my future money, & probably a shrine if this keeps working.
Great image results! Only suggestion, is its not as accurate for line drawings and text, would be awesome if in future it could train to get them more accurate
Amazing service and huge respect on keeping it free. Clean and simple UI and waiting time isn't long. Results look fabulous.
Does what it says on the tin, very effective tool for what it's designed for - much better than most of the alternatives. Only downside is the wait time and the aggressive pop-up ads, but the wait time is understandable and the ads can be easily mitigated.
VERY EPIC. DIRECT, SO EASY TO USE, AND REEEEEEEAALLLY DELIVERS. Good job! ',:D It does in fact upscale your image. I didn't count how much time it took with a chronometer, but it isn't more than ten minutes, and I am OK with that! The service is worth it.
