Question: How can I upscale my low-resolution images to 4K without breaking the bank?

The first project, Let's Enhance, is an AI image enhancement tool that can upscale and denoise low-resolution or blurry images to high resolution and high quality, including 4K. It's a good all-purpose tool with batch processing, HDR filters and background removal, and it's geared for creative pros and e-commerce businesses. You can try it for free with a trial account and then pay by the credit.

Another good option is Nero AI, a desktop tool that uses AI to upscale photos and videos up to 4K resolution. It's got batch processing, real-time preview and GPU acceleration for speed, and it's good for product photos and videos. It can handle a variety of file formats, including JPG, JPEG, PNG and more.

If you prefer a cloud-based tool, TensorPix is a collection of AI-based tools to process multimedia files without installation. It's got upscaling to 4K, noise reduction and video framerate increase, and it's good for people with some editing ability. With different pricing tiers and an emphasis on accessibility, TensorPix is a good option for those who want to improve image and video quality in the cloud.
