Best free image enhancer AI tool for improving image quality?

When using image enhancer AI, especially for improving image quality, there are some common pitfalls to watch out for to ensure you get the best results and preserve your original images. Here are key errors to avoid:

What happens: Pushing images to very high resolutions or excessive sharpening can create unnatural artifacts, noise, or overly smooth areas.
How to avoid: Use moderate settings and preview results before applying large enhancements. Stick to recommended upscaling factors (e.g., 2x or 4x).

What happens: Starting with an extremely low-quality or heavily blurred photo limits the AI's ability to recover detail effectively.
How to avoid: Accept that some images may not improve significantly. For very poor images, consider manual editing or retaking photos if possible.

What happens: Free or poorly designed image enhancer AI may produce inconsistent or low-quality results, or even compromise your privacy.
How to avoid: Stick to reputable, well-reviewed AI tools and avoid uploading sensitive or personal images to untrusted sites.
