Images saved too many times or downloaded from social media get blocky. Smooth them out.
JPEG compression divides images into 8×8 blocks. At low quality, these blocks become visible, gradients band, and edges get mosquito-like halos. Every re-save makes it worse.
A denoising network trained on compressed images removes blocks and halos, giving a clean base for printing or upscaling.
Upload the compressed JPG: Ideally the least-compressed copy you can find.
Run the Image Denoiser: Removes blocks, banding and halos.
Save as PNG: Avoid re-compressing the cleaned image as a low-quality JPG.
Blocks smoothed: 8×8 squares disappear in skies and skin.
Halos reduced: Edges around text and objects clean up.
Upscale-ready: Artifacts are removed before enlarging.
Why do social media images look worse? Platforms re-compress uploads to save bandwidth, adding artifacts each time.
Can I avoid artifacts in the future? Save masters as PNG or high-quality JPG (90+), and edit from the master, not from copies.
Does it fix banding in skies? It helps significantly with banding caused by compression.
