What does image quality enhancement mean?
Image quality enhancement describes a range of edits that can make an image more useful at its intended size. Lem Gen's enhancer requests a 2× AI upscale, increasing the pixel dimensions while estimating visual detail. It is not a guaranteed repair for blur, noise or color, and generated detail may differ from what was in the original scene.

Frequently asked questions
How can I enhance image quality online?
Open the image enhancer and upload a supported file. The tool requests 2× upscaling; review the visible cost and compare the result with your original after processing.
Does enhancing an image recover missing details?
Not reliably. AI estimates details based on the input and can produce plausible textures that differ from the original. Review important details instead of treating the output as a factual reconstruction.
Will it fix blur, noise or color automatically?
The tool uses an AI upscaler that may change the appearance of detail, but improvements to blur or noise vary. It does not provide separate controls for color, exposure, sharpening or noise reduction.
What file formats and sizes are supported?
Upload one JPG, PNG or WebP file up to 10 MB. At 2×, the requested output must fit within a 3,840-pixel longest side and 3,840 × 2,160 total pixels.
How much does image enhancement cost?
The standard cost is 100 credits per image, including smaller images. Eligible plans may receive a discount; sign in and check the displayed account price before submitting.
Does every image become 4K?
No. The tool requests twice the input width and height. For example, 1920 × 1080 corresponds to 3840 × 2160 at 2×; smaller inputs generally produce smaller results, and processing remains subject to service limits.
Do I need an account and can I control visibility?
Sign-in is required to create a task. Review the visibility control before submitting: free-account generations are public, while eligible paid accounts can choose private visibility.
Can I enhance photos for a product listing or print?
You can try it on images you have permission to edit. Check product labels, colors and the intended print size carefully because AI can change fine details.
