How it works

Upload your compressed photo

Drop your over-compressed image into EditThisPic. Works with JPG, PNG, WebP up to 7MB. The tool handles images saved at low quality settings, heavily compressed social media downloads, or photos with visible blocky artifacts.

Expect: Simple cases with mild artifacts: 15-30 seconds. Heavy compression with lots of damage: may need 2-3 refinements to restore all detail.
Describe what you want

Type your instruction: 'remove compression artifacts and restore smooth gradients' or 'fix blocky sky and restore natural detail.' Be specific about which areas need work—skies, skin tones, gradients. No marking needed—the AI understands what compression artifacts look like.

Tip: Mention the type of artifact: 'blocky sky', 'banding in gradients', or 'pixelated edges' helps the AI target specific issues.

Generate and review

AI analyzes compression patterns and reconstructs smooth detail. Zoom to 100% to verify artifacts are gone and gradients look natural. Check areas that were most compressed—usually skies, smooth backgrounds, or skin tones.
Refine with markers if needed

If some blocky areas remain or certain zones need more work, tap markers on those specific spots and regenerate. This is optional—most compression fixes work without markers.

Tip: Markers are for targeting stubborn artifact areas. Try without them first—most images clean up completely on first attempt.

If something looks off

AI changed the wrong area or something I didn't want changed

Why: The AI couldn't determine exactly which compressed areas you meant from description alone. This happens when artifacts appear throughout the image.

Try: Tap a marker on the specific blocky or artifacted area you want to clean up, then regenerate with the same prompt

Try This →

Tip: Markers tell the AI 'fix THIS compressed area specifically.' Use them when artifacts vary across the image.

Some blocky areas still visible after cleanup

Why: Severe compression damage may need multiple passes. The AI prioritizes preserving detail over aggressive smoothing.

Try:

regenerate with: 'more aggressively remove remaining compression artifacts' or mark the stubborn blocky areas and try again

Try This →

Image looks too smooth or detail was lost

Why: The AI over-smoothed while removing artifacts, losing legitimate detail along with compression damage.

Try: regenerate with: 'remove compression artifacts but preserve all original detail and texture'

Try This →

Colors look different after artifact removal

Why: Heavy compression often damages color information. Reconstruction may shift colors slightly as it fills in missing data.

Try: Try: 'remove artifacts while preserving exact original colors' or adjust color separately after artifact cleanup

Try This →

Edges look soft or blurry after cleanup

Why: Artifact removal can soften edges as it smooths blocky areas. The AI may need to know you want sharpness preserved.

Try: regenerate with: 'remove compression artifacts while keeping edges sharp and defined'

Try This →

New artifacts appeared that weren't there before

Why: The reconstruction process sometimes creates new patterns when filling in heavily damaged areas.

Try:

Try a lighter touch: 'gently reduce compression artifacts without creating new patterns' or mark problem areas for targeted fixing

Quick answers

Do I need to mark the compressed areas before describing?

No! Just describe what you want: 'remove compression artifacts from sky' or 'fix blocky areas throughout.' The AI recognizes compression patterns automatically. Only use markers when you need to target specific areas that didn't clean up on the first attempt.

How do I remove compression artifacts from a photo for free?

Upload your over-compressed image to EditThisPic and type 'remove compression artifacts and restore detail.' The AI analyzes blocky patterns, banding, and JPEG artifacts, then reconstructs smooth detail. Free to use, no account needed, no watermark on results.

Can this fix photos saved at very low JPEG quality?

Yes, the AI handles JPEG artifacts from low-quality saves, including blocky areas, color banding, and lost detail. Severe compression may need 2-3 refinements. The tool works best when some detail remains visible—it can't fully restore information that was completely destroyed.

Will this work on photos downloaded from social media?

Yes, social platforms heavily compress uploads. The tool removes Facebook, Instagram, and Twitter compression artifacts. Results depend on how much detail survived—mildly compressed images restore well, while multiple re-compressions may limit what's recoverable.

What's the difference between compression artifacts and noise?

Compression artifacts are blocky squares, banding, and color patches from over-compression. Noise is random grain from high ISO or low light. This tool fixes compression damage. For camera noise, use our AI Noise Remover instead.
