What is JPEG Artifacts – The Ultimate Guide to Fix It and Enhance Quality

Last Updated on October 13, 2022 by Peter Wood

If you download some JPEG photographs online or zoom in on a JPEG file, the JPEG Artifacts should be a headache problem. The JPEG needs to compress first to provide a smooth experience for the website. When you download the JPEG file again, JPEG compression artifacts and image noise affect the quality of the photos.

What should be the differences between JPEG artifacts and image noise? How to eliminate the JPEG artifacts you downloaded online? When you want to learn more about the noise for JPEG compression, you can learn more about the information from the article.

What is JPEG Artifacts

Part 1: What is JPEG Artifacts

Just as the name of JPEG Artifacts, JPEG artifacts are caused by compression saved in JPEG files. JPEG Artifacts are the blocky or blotchy areas of an image. JPEG Artifacts are the aggressive data compression result or conversion between different formats that cause the discard of some image data. The artifacts should ruin any great image. You should know the methods to repair JPEG Artifacts for a better photograph.

JPEG Compression Artifacts are mosquito noise (noise around edges), blurring, and a smeared appearance in the region. How can you find the JPEG artifacts within an image? Usually, when there are some flat blocks, you need some solutions to eliminate JPEG compression artifacts.

Part 2: JPEG Artifacts V.S. Image Noise

As the information mentioned previously, image noise is also called JPEG Artifacts. JPEG artifacts are from compression. And image noise is caused by the side effect of shooting. And compression JPEG artifacts are also different from image noise in the processes involved with capturing and saving an image.

There are similarities due to the differences between JPEG artifacts and Image noise. Both JPEG artifacts and Image noise have some negative photo effects.

Part 3: 2 Major Technology to Eliminate JPEG Artifacts

Various approaches can turn a blur into an image without Artifacts. Here are two frequently used methods you can follow below.

1. Advanced Compression Techniques. Some advanced compression methods can achieve a compressed photo without any artifacts to avoid JPEG artifacts caused by compression.

If you need to use the compressed photos on your website, you can save them to the web format of Photoshop without any JPEG artifacts. And some Photo Converters can also be used to avoid artifacts as well.

2. Photo Denoise Programs. If you need to turn a blurred image with JPEG compression artifacts into a better one, some photo denoise programs should be a great help, such as Topaz Denoise and WidsMob AI Retoucher. Both programs provide AI algorithms to enhance photo quality, remove image noises, and reduce image artifacts.

Besides the compression algorithm, the JPEG artifacts reduction algorithm should be another solution post-processing method to achieve a good result. You should pay attention to the regular noise reduction software does not work well for fixing JPEG artifacts caused by compression.

Before eliminating JPEG artifacts, you can save a copy of the original file when you compress the file or fix the artifacts with Photo Denoise programs. If there is any other solution to handle JPEG artifacts, you can share the information.

Part 4: How to Reduce JPEG Compression Artifacts

How to Reduce JPEG Compression Artifacts with AI Retouch

Is there a method to reduce JPEG compression artifacts or image noises? When you want to enhance the quality of JPEG files, WidsMob AI Retoucher is a good solution you can consider. It will preserve exceptional details, outstanding image quality, and a distinctive natural look for the JPEG compression artifacts photo. Moreover, there are 3 different AI retouching methods to reduce image noise, recover low light, and remove haze from images. Of course, there are more advanced AI features, such as AI Cartoonize, AI Portrait, AI Mosaic, AI Style Transfer, and more you can apply.

1. Reduce JPEG artifacts with lowlight recovery, noise reduction, and haze removal.

2. Balance sharpness, chrominance, and luminance to remove JPEG image artifacts.

3. Adjust multiple enhancements, color adjustments, and noise reduction parameters.

4. Provide AI portrait features to whiten skin, soften face skin, and reduce blemishes.

Step 1: Download and install WidsMob AI Retoucher, you can launch the program and click the Import option to load the download image with JPEG artifacts into the program. After that, you can choose the image and select the Edit button to fix the imperfection accordingly.

Import Photo Retoucher

Step 2: Go to the Adjust menu on the right toolbar and scroll down to select the Sharpness option. It will reduce the JPEG artifacts but also generate image noise. Just tweak the luminance and chrominance from the Noise Reduction menu to get the optimal image.

How to Remove JPEG Compression Artifacts with AI Image Upscale

As mentioned above, JPEG artifacts is the result of compression, you can simply follow the opposite way to remove JPEG artifacts. WidsMob ImageConvert is the desired AI image enhancer to upscale the image quality with the original quality. It enables you to upscale the image up to 4X within 3000 pixels. If you do not have a special requirement for the image size, it should be the optimal choice.

1. Remove the JPEG artifacts and enhance the image size with AI image upscale.

2. Enhance image quality to 4X the original file size and retain the optimal quality.

3. Upscale, preview, and download the JPEG artifacts images without the Internet.

4. Support 3000 pixels compared to most online image enhancers with 2000 pixels.

Step 1: Download and install WidsMob ImageConvert, you can launch the program on your computer. After that, you can click the Import button to add the images with JPEG artifacts into the program. Of course, you can also drag-n-drop them into the program easily.

Import Image for Upscale ImageConvert

Step 2: Double-click the image. You can click the AI Super Resolution icon to enter the upscale window, and select the 4X option from the Scale Mode, which will enhance the file size and reduce the compression artifacts. Click the Apply button to check the changes.
