What JPEG quality does to an image
JPEG quality controls how much visual detail is kept when an image is saved as a JPG. At high quality settings, the image may look almost unchanged. At low quality settings, the lost detail becomes visible as blocky artifacts, rough color transitions, softened edges, and messy texture around text or sharp outlines.
That is why JPEG quality settings matter when you want a low-quality image on purpose. They can make a clean photo look copied, re-uploaded, old, or damaged. An image quality degrader, also called an image quality decreaser, lets you control JPEG compression, pixels, blur, color, and noise instead of relying on one automatic export setting.
The important detail is intent. Normal image optimization tries to hide compression artifacts. A low quality image maker exposes them as part of the style, while still keeping enough information for the picture to be useful.
Best JPEG quality settings by goal
There is no single perfect JPEG quality number. The right setting depends on whether you want a smaller file, a realistic low-quality copy, or an obviously crunchy meme image. Use this table as a starting point for JPEG quality settings, output scale, and visible degradation, then check the preview and result size.
| Goal | JPEG quality | Output scale | Blur | Noise | Expected result |
|---|---|---|---|---|---|
| Smaller image for slow internet | 40-60 | 70-90% | 0-1 | 0-12 | Noticeably smaller file with the subject still clean enough to read. |
| General low quality image | 25-40 | 50-80% | 1-2 | 8-22 | Visible artifacts, soft details, and a copied-photo feel. |
| Crunchy meme image | 10-25 | 35-65% | 0-1 | 25-55 | Rough edges, noisy texture, and obvious repost damage. |
| Fake screenshot | 30-50 | 60-85% | 0-1 | 6-18 | Compressed UI or text that still stays readable. |
| Deep fried image | 5-20 | 35-60% | 0 | 35-70 | Heavy artifacts, strong color, harsh contrast, and meme damage. |
JPEG compression level and output scale
JPEG quality changes how much detail is kept during export. This is also what people often mean by JPEG compression quality: higher quality keeps cleaner edges and smoother color, while lower quality increases the compression level and makes artifacts easier to see. Resolution changes how many pixels the image has. If you only lower JPEG quality, a large photo may still look fairly clean at normal screen size. If you lower output scale first and then save as a low-quality JPG, the damage becomes easier to see and the file is often much smaller.
A practical workflow is to set Output scale to 50-80% for a believable low quality photo. For a meme, you can go lower so the blocky pixels and JPEG artifacts become part of the final look.
This matters for slow internet too. Smaller dimensions plus lower JPEG quality can reduce file size much more than quality alone, especially for large camera photos and screenshots. If your goal is the best JPEG quality for smaller files, start with scale and quality together instead of pushing quality to the lowest possible number immediately.
Compression vs blur vs pixelation
Compression, blur, and pixelation all make images worse, but they do it in different ways. Compression creates square artifacts and rough edges. Blur removes sharp detail. Pixelation turns the image into visible blocks. Noise adds random texture that makes the result feel gritty or crunchy.
For a natural low quality image, compression should usually be the main effect. Add only a small amount of blur or pixelation after the JPG artifacts are visible. For a meme or deep fried image, combine stronger compression with noise, saturation, contrast, and sharper edges.
Simple rule
Use JPEG quality when file size and artifacts matter. Use blur when the image should look soft. Use pixelation when you want a low-resolution block effect. Use noise and color when the result should look crunchy, messy, or meme-like.
Recommended settings in Bad Quality Image Maker
If you use Bad Quality Image Maker, start with a preset instead of guessing every control from zero. Then adjust JPEG quality first, because it has the clearest effect on both visible damage and output file size.
| Preset | JPEG quality range | Best use |
|---|---|---|
| Bad Quality | 32-42 | Use it for a believable bad quality image that still looks like a normal shared photo. |
| Low Quality | 28-40 | Use it when you want to make a photo look low quality without making it unreadable. |
| Pixelated | 25-38 | Use it when blocky pixels matter more than file-size reduction. |
| Crunchy | 12-24 | Use it for meme reposts, noisy reaction images, and intentionally rough social posts. |
| Deep Fried Meme | 8-18 | Use it when the image should look heavily damaged, loud, and exaggerated. |
How to create a low quality image online
- Open the Bad Quality Image Maker tool.
- Upload a JPG, PNG, or WebP image from your device.
- Choose Bad Quality, Low Quality, Crunchy, or Deep Fried Meme.
- Lower Output scale first if file size or low-resolution texture matters.
- Lower JPEG quality until artifacts become visible.
- Add blur, pixels, noise, or color only when the image still looks too clean.
- Compare the original KB and result KB under the previews, then download the JPG.
This browser-based workflow is useful when you need to make a photo look low quality quickly, reduce image file size, or create a deliberately degraded version for a joke, repost, profile picture, or fake screenshot.
JPEG quality comparison
This comparison uses one source JPEG at the same 900x900 size for every output. The image is not converted from PNG in this test, and the dimensions do not change between thumbnails. Only the JPEG quality value changes.
Quality 80 works as a near-original baseline. Quality 60 keeps the image fairly clean while reducing size. Quality 40 starts to show rougher gradients. Quality 25 is a practical low quality image setting. Quality 15 and 8 are intentionally harsh, with stronger artifacts and a more damaged meme-style look.

Common mistakes with JPEG compression
Starting too low
If you start at 5% quality, the image may become unreadable before you learn which settings actually matter. Start around 30-40%, preview the result, and then push lower if you need more damage.
Using noise when file size matters
Noise can make an image look crunchy, but it can also make the file harder to compress. If your goal is a smaller image for slow internet, lower Output scale and JPEG quality before adding noise.
Forgetting the final display size
A low quality photo may look mild on desktop and much stronger on a small phone screen. Check the image at the size where people will actually see it.
Try the settings in the free online tool
Use Bad Quality Image Maker as a free online image quality degrader. Upload an image, choose a preset, tune JPEG quality, compare the original and result size, and download a deliberately lower-quality JPG.

If you are still deciding what counts as a low quality image, read What Is a Low Quality Image? for the meaning, examples, and low quality vs low resolution comparison.
If compression artifacts are not enough, use the pixelation guide to make the image look more visibly blocky and damaged.
For the main tool, use the Low Quality Image Maker. For one-control-at-a-time damage, use the Image Degraderor the Deep Fried Meme Generator.
FAQ
What is the best JPEG quality for low quality images?
For a clear low-quality JPEG effect, start around 25 to 40 JPEG quality. Use 40 to 60 for smaller but still clean images, 15 to 25 for crunchy meme images, and below 15 only when you want heavy artifacts.
What JPEG quality setting is best for smaller files?
For smaller files that still look usable, try JPEG quality 50 to 70 first. For a deliberately low-quality image, use 25 to 40. Lower values usually save more space, but the visible artifacts become much stronger.
What does JPEG compression level mean?
JPEG compression level describes how aggressively the file is compressed. In most browser tools, a lower JPEG quality value means a stronger compression level, smaller files, and more visible artifacts.
Is JPEG compression quality the same as JPEG quality?
In practical online tools, JPEG compression quality and JPEG quality usually refer to the same export control. Higher quality keeps more detail and creates larger files. Lower quality creates stronger compression and a more damaged look.
What setting makes a low quality JPEG look crunchy?
Use JPEG quality around 10 to 25, then add moderate noise, stronger contrast, and a little sharpening. Avoid too much blur because crunchy images need rough edges and visible compression texture.
Can I make a photo look low quality without installing software?
Yes. You can use a browser-based tool to upload the image, adjust JPEG quality and degradation settings, compare original and result sizes, and download the compressed JPG.
