When to use it
Use it for compression blocks, irregular noise around text, faces, or objects, color banding in skies and shadows, and images saved many times. For random camera grain, use AI Denoiser. For soft focus or motion blur, use AI Deblurrer.
ABOUT ARTIFACT CLEANERUnderstand compression artifact cleanup
AI Artifact Cleaner: reduce compression blocks and defects
AI Artifact Cleaner helps reduce defects left by heavily compressed images, files repeatedly shared through apps, repeatedly saved JPGs, and video frames. It is useful for blockiness, gradient stains, halos near edges, jagged lines, and broken texture. Always compare the result: stronger cleanup may also soften real details.
Start gently
Artifacts and real detail can look alike. Fine lines, hair strands, fabric texture, and intentional grain can be softened when cleanup is too strong. Begin low, inspect at high zoom, and raise it only if blocks and stains remain.
Video frames and social-media images
Screenshots, thumbnails, messenger images, and video frames often contain aggressive compression. The tool can improve visible damage, but it cannot precisely recreate details removed from the original file.
Batch work and comparison
You can use one setting for many files, but compression varies between images. Test a representative file first. If a batch mixes photos, illustrations, and video frames, process them separately for better control.
Frequently asked questions
What are image artifacts?
They are visual defects such as blocks, stains, halos, banding, and broken texture, usually caused by compression or repeated sharing.
Can it improve heavily compressed JPGs?
It can reduce visible defects, especially blocks and stains, but cannot perfectly restore details that are already gone.
How is it different from AI Denoiser?
AI Denoiser targets random grain and noise. Artifact Cleaner targets compression blocks, halos, and encoding damage.
Can cleanup make an image worse?
Too much cleanup can soften real detail. Lower the strength if text, skin, hair, or fine lines lose definition.
Does it work on video frames?
Yes. Video frames and screenshots are common use cases, though results depend on the original compression.
Can I process multiple images?
Yes. Test one representative image, then apply the chosen setting to the batch or selected files.
Moderate cleanup almost always preserves the image's natural appearance better.

How to use AI Artifact Cleaner
Recover heavily compressed images, messaging-app screenshots, and video frames without changing resolution by default.
- 1Import the image with blocks, ringing, or compression-damaged detail.
- 2Choose JPEG for compressed photos and images; use H.264 for frames extracted from video.
- 3Adjust strength and inspect enlarged text and edges in the comparison.
- 4Process and export if artifacts shrink without erasing legitimate detail.
The H.264 model is for video frames already saved as images; it does not process video files directly.
