Quick answer: The tool below starts from a lower quality preset that only reduces JPEG quality. Pixelation, blur, saturation, contrast, and noise are all set to neutral so the result is a compressed, softer copy of the original.
Use this page when you need to lower the quality of an image in the browser — also called reducing image quality or decreasing image quality online. Lower image quality by controlling JPEG compression, output scale, pixelation, blur, and noise — whether you want to reduce photo quality slightly, make a picture look much rougher, or anything in between.

Common situations where this tool helps.
Each tool below focuses on a different part of the image quality workflow.
These terms often overlap in search, but they describe different ways an image can become smaller, rougher, or less clear.
| Concept | What it means | Best for | Main controls |
|---|---|---|---|
| Reduce image quality | Make the image look worse by removing detail or adding visible artifacts. | Repost effects, rough screenshots, memes. | JPEG quality, pixel size, blur, noise |
| Reduce image resolution | Export fewer pixels so the image has less detail. | Smaller images, old-web look, thumbnails. | Output scale |
| JPEG compression | Keep similar dimensions but lower detail in the JPG export. | Copied-photo look, smaller file. | JPEG quality |
| Image quality reducer | A tool or workflow that combines compression, scale, and visible degradation. | Flexible quality reduction. | Output scale, JPEG quality, pixels |
Use these ranges when you want to reduce image quality visibly while keeping the result understandable. Lower JPEG quality first, then add scale, pixels, blur, or noise only when the image still looks too clean.
| Target | Starting settings | Use when | Note |
|---|---|---|---|
| Light quality reduction | Output scale 85-100%, JPEG quality 35-50 | The image should look slightly compressed but still clean. | Add blur 0-1 only if it is too sharp. |
| Reposted image look | Output scale 70-90%, JPEG quality 22-35, pixel size 2-5 | You want social-media or messaging-app damage. | Keep noise below 25 for believable results. |
| Low quality meme | Output scale 55-80%, JPEG quality 12-25, pixel size 5-12 | The image should look rough and funny. | Add contrast and saturation after compression. |
| Fake screenshot damage | Output scale 80-100%, JPEG quality 25-40, pixel size 1-4 | Text still needs to be readable. | Keep blur at 0 or 1. |
| Small rough JPG | Output scale 45-70%, JPEG quality 10-24 | Smaller file and visible quality loss both matter. | For strict KB targets, use the KB-first page instead. |
Use these steps for a reliable result.
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 |
|---|---|---|---|---|---|
| Slightly lower quality | 32-48 | 1-3 | 0-1 | Saturation 90-115 | 0-12 |
| Noticeably lower quality | 20-35 | 3-7 | 1-2 | Contrast 105-140 | 10-28 |
| Rough lower quality | 12-24 | 5-10 | 0-2 | Saturation 85-130 | 20-45 |
| Very low quality | 6-16 | 8-15 | 0-1 | Contrast 120-170 | 35-65 |
Use these notes to avoid results that are either too clean or too damaged for this specific effect.
JPEG compression creates the most recognizable quality loss. When you lower JPEG quality, the image develops visible compression blocks, soft edges, and color bleeding. Start here before touching pixel size, blur, or noise, so the result looks like a real re-uploaded file instead of a broken effect layered on top of a clean image.
Output scale lowers the exported pixel dimensions. This usually drops file size faster than extreme compression alone. If the result is still too large after lowering JPEG quality, reduce scale next before pushing quality below 15.
Blur makes an image feel soft or out of focus, which works well for photos and faces. Pixelation creates blocky squares that work better for screenshots, meme panels, and images with large flat color areas. Choose one as the main damage source before mixing both.
The goal is to lower the quality of an image, not destroy it. If the subject disappears, reduce pixel size first, then raise JPEG quality slightly until the content is readable again.
These examples show common before and after directions for this effect.

Answers for this specific image-quality effect.
Upload the image, lower JPEG quality first, then adjust Output scale, pixel size, blur, or noise until the preview looks right. The image is processed in the browser, so you can preview and download the lowered copy without uploading to a server.
Lowering JPEG quality is the easiest single control. Drag the JPEG quality slider down until compression artifacts appear, then download the result as a JPG. Most lower quality results only need JPEG compression, with Output scale added when you also need a smaller file.
Not exactly. Compression reduces file size while trying to preserve appearance. Lowering the quality of an image intentionally makes it look worse. You can combine both goals by using JPEG quality and Output scale together on this page.
Yes. Keep Output scale at 100% and use JPEG quality, pixelation, blur, and noise to change the visual appearance without reducing the exported pixel dimensions.
Usually yes, but not always. Lowering JPEG quality almost always produces a smaller file, but adding noise can sometimes increase file size because noise adds detail that compression must encode. Check the original KB and result KB under the preview before downloading.
Lowering quality changes how the image looks through compression, blur, pixelation, or noise. Reducing resolution changes the number of pixels, which you can do with Output scale. You can combine both on the same image for a stronger overall effect.
