What Our Happy Customers Say

Antonetta H. Youtube Creator

I’ve been working hard to grow as a YouTuber. I started by posting some Shorts, but the views were disappointing, and I realized the low quality might be the reason. I started using Artguru to upscale my videos to HD before posting, and while it wasn’t an overnight explosion, the new videos are clearly getting more views and even some new subscribers. Until I can buy high-end camera, I’ll definitely stick with Artguru.

Grover H. Anime Lover

There’s a strange contradiction for me: technology is so advanced, yet we’re often stuck with blurry versions of the anime we grew up with. Since the internet didn’t preserve them in HD, I took matters into my own hands. I used Artguru to upscale all 13 episodes of my favorite series one by one. Now I have the original and the 4K version to enjoy as I want haha.

Ella S. Driver

It was only a few years after my mother passed away that I found some old videos of her. I was overjoyed, but the quality is not good. So I searched everywhere for a tool to restore her image, and Artguru was at the top of my list. I truly hope Artguru continues to improve its performance, and when that happens, I’ll be back to upscale them all over again.
