Use this image quality degrader when you want precise control over how a picture breaks down. An image quality degrader, also called an image quality decreaser, lets you control JPEG compression, pixels, blur, color, and noise.
The tool on this page starts from a crunchy degradation preset, which makes changes easy to see before you dial settings up or down for your specific image.
These use cases are specific to image quality degrader rather than the broader homepage tool.
Follow this workflow when you want the page preset to produce the intended visual style.
Start from the embedded preset, then use these ranges to tune the result for a specific target.
| Goal | JPEG quality | Pixel size | Blur | Color | Noise |
|---|---|---|---|---|---|
| Controlled degradation | 24-42 | 3-8 | 0-2 | Saturation 90-140 | 12-35 |
| Crunchy texture | 10-22 | 6-12 | 0-1 | Contrast 150-210 | 45-70 |
| Blurred degradation | 32-50 | 1-4 | 4-8 | Saturation 80-120 | 8-20 |
| Pixel damage | 18-34 | 12-24 | 0 | Contrast 100-150 | 10-30 |
Use these notes to avoid results that are either too clean or too damaged for this specific effect.
For controlled degradation, choose the main source of quality loss first. JPEG quality creates compression artifacts, pixel size creates blocky structure, and blur removes detail. Mixing all three heavily can make the result hard to diagnose.
Screenshots and interface images show degradation quickly around text, icons, and thin lines. If those edges disappear too fast, raise JPEG quality or reduce pixel size before changing color controls.
Noise is useful for rough texture, but it can also increase file complexity. If you need a smaller degraded image, lower JPEG quality before increasing noise.
These examples show common before and after directions for this effect.

Soft degradedAnswers for this specific image-quality effect.
JPEG quality usually has the strongest overall effect. Pixel size changes the structure, blur softens detail, and noise adds a rough texture.
Yes. The goal is visible degradation, not clean optimization. Use the preview to choose the amount of damage you want.
Noise adds visual detail that JPEG compression may need more bytes to store. Lower the JPEG quality if file size matters.
Yes. The tool downloads the processed result as a JPG using the current quality setting.
Resizing changes image dimensions. This image quality degrader changes visible quality by adjusting compression, pixelation, blur, color, contrast, and noise.
Lower JPEG quality first. If noise is high, reduce it slightly because noise can add detail that makes JPG compression less efficient.
