JPEG compression artifact simulation
Use this JPEG Artifact Generator to add blocky JPEG artifacts, color smearing, ringing, and repeated compression damage to an image in your browser.
Upload an image, adjust JPEG quality, recompression passes, and artifact intensity, preview the result, and download an image that looks repeatedly compressed.
Drag the slider to adjust image quality.
What is JPEG Artifact Generator?
JPEG Artifact Generator is a browser-based tool for add jpeg artifacts to image. It helps when You specifically want JPEG compression marks rather than generic blur, pixelation, or file-size reduction.
Instead of using a generic editor, you can upload an image, choose a preset built for jpeg artifact generator, preview the output, and download a new low-quality file without changing the original.

Pro Tips for Creating JPEG Artifact Generator
How to use this tool
Lower values add visible compression blocks, color smearing, and ringing around edges. Raise it when faces or captions become too hard to read.
A smaller scale removes real detail before export. It is the fastest way to make a clean image feel like a small file that was enlarged again.
Pixelation draws the image through larger blocks. Use it for retro, game-like, low-res, or intentionally cheap social graphics.
Blur softens sharp edges and makes screenshots or photos feel copied, saved, or taken with a weak camera.
Noise adds rough texture over flat areas. Small amounts feel like an old sensor or repost; heavy noise creates a dirtier meme look.
Extra passes save the processed image again and again. This makes compression damage compound like a file that has been reposted many times.
Before
A clean image with smooth color areas.
After
A JPEG with mild edge ringing and slight banding while the subject remains clean.
Use light artifacts when you need realism without obvious destruction.
Before
A screenshot, meme, or photo with strong contrast.
After
A visibly damaged image with blocks, smears, and repeated compression haze.
Use heavy artifacts when the compression damage itself should be the style.
Create visual examples of how JPEG compression damages edges, gradients, and color transitions.
Make an image look like it has been downloaded, uploaded, and saved several times.
Add the familiar blocky texture that makes screenshots and reaction images feel reposted.
Simulate old, low-quality web images without changing the subject or layout.
A JPEG Artifact Generator is useful when the goal is not just a smaller image, but the recognizable look of lossy compression. JPEG artifacts have a specific visual language: block boundaries, mosquito noise around edges, smeared color, banding in gradients, and a dull haze from repeated saves.
To create the effect, keep the output format set to JPEG. Lower quality until the artifacts appear, then add recompression passes if you want the damage to feel accumulated. Scale can stay higher than it would on a general degrader page because the focus here is artifacting, not necessarily low resolution.
Artifacts show more clearly on some images than others. Screenshots with text and hard UI edges reveal ringing quickly. Smooth gradients show banding. Busy photos can hide artifacts until quality becomes very low. Use the before-and-after preview to judge the actual source instead of assuming one number works for every file.
If you want a complete meme or ugly image effect, move to the Low Quality Meme Maker or Bad Quality Image Maker. This JPEG Artifact Generator stays focused on compression marks so the page matches the specific search intent: add JPEG artifacts to image.
JPEG artifacts are especially recognizable because they appear in places where people have seen low-quality files for years: copied screenshots, old forum images, compressed email attachments, and social uploads. Adding artifacts can make a clean file feel older or less official without changing its composition. That makes this page useful for examples, jokes, mockups, and visual texture studies.
The artifact intensity should match the source. On a face, too much compression can turn expression into mush. On a UI screenshot, moderate compression may be enough because text and hard edges reveal damage quickly. On a flat illustration, color smearing and banding can appear before block boundaries are obvious. Use quality and passes as separate controls so the result stays intentional.
If the preview does not show enough artifacting, first lower quality. If the artifacts appear but feel too fresh or clean, increase recompression passes. If the image becomes too small or blurry, raise scale because resolution loss is not the main effect here. This order keeps the page focused on JPEG artifacts instead of turning it into a general low-quality image maker.
For clearer artifact examples, choose images with edges and contrast. Text, UI panels, logos, and sharp object outlines reveal ringing and block boundaries more quickly than noisy photos. Smooth skies and gradients reveal banding and color smear. If your source is already busy, you may need lower quality or more passes before the artifact pattern becomes visible in the preview.
Keep the output believable by avoiding unrelated damage when artifacts are the goal.
Upload an image, adjust JPEG quality, recompression passes, and artifact intensity, preview the result, and download an image that looks repeatedly compressed.
