JPEG image format and its compression
Some users save images for making memes and sharing them with their friends. Other Internet surfers use photos for social networks. Designers and website owners fill their blogs and eCommerce websites with pictures. That’s funny, but sometimes a user is not even aware of which image format is being used. However, when it comes to photo compressing, it’s essential to pay attention to the type of picture extension.
Image compression deals with resizing image weight twice and more. Along with that, the quality of the photo is frequently being lost. In fact, the sense of image compression algorithm refers to highlighting a few pixels and replacing them by one or two with a similar color. That’s why sometimes pixel clusters look like spots on a photo.
JPEG format is one of the most popular formats together with .png, .bmp, .gif, and .tiff. JPEG files are being transformed with a compression method that allows us to significantly reduce the file size without significant quality loss at the same time.
Advantages of JPEG image format
- JPEG, the most popular format among formats of raster files, is an abbreviation for Joint Photographic Experts Group. Digital cameras save photos in JPEG. The user may also face relatives of this extension like .jpg and .jfif. Thanks to its features, JPEG files are so widespread.
- This photo format is fairly compatible with image processing applications. It means that most of the software for image editing works with .jpeg. That’s amazing! No need to search suitable apps for enhancing/enlarging/compressing a particular picture extension.
- JPEG images work also with most of the printers and other hardware units. This allows us to print images without problems.
- Thanks to the high-quality photos saved in JPEG format, this extension is perfectly suitable for producing dynamic photos. Other image formats would save blurred images, while JPEG supports sharp pictures.
- JPEG standard allows compressing a photo until it takes 5% of its initial size. Just imagine! 95% of the pixels can be lost! This extension is ideal in case of further reducing size is needed.
Why JPEG compression is necessary
The compressed images take less space on the device. It makes photo library owners, bloggers and just fans of memes find the way of reducing photo weight.
- In some cases it’s crucial. For instance, website performance optimization. One of the most frequent reasons for low page speed is an enormous number of bulky photos on the website. While talking about an eCommerce web store, reducing the number of items would not be an option. That’s why the designer needs to compress images to make them lightweight.
- For the last couple of years, people use quick photos instead of a printed text. Sounds familiar? Sometimes it’s really more convenient to take a picture and send it in a messenger with words: “no time to explain, just look at this”. The small-sized image is being displayed much more promptly than a heavy-sized one.
- Additionally, compressed shoots are super comfortable for adding to .pdf and .doc files. The user can insert them quickly without setting up dimensions.
- Some website developers configure lazy loading. It means, that the page and the text are displayed super fast, however, images load a bit slowly. Modern Internet users don’t like to wait forever for a webpage to download fully. They just leave the website which doesn’t load promptly and visit the one which does.
- Some old models of smartphones and laptops support lightweight photos only. Sharpened but bulky images won’t display there at all. It is one more reason for JPEG compression importance.
Possible consequences of JPEG image compression
This format is not protected against generational degradation. It means that the quality will be getting lost with every separate editing and saving. Eventually, the JPEG repair may be needed.
The main headache of picture compression is JPEG artifacts. Artifacts are the extra pixels around the objects on a photo. Even the most breathtaking image may lose its worth because of this ugly noise.
Content losses also take an important place. Taking into account how the algorithm actually works the tiny parts of the image would just disappear. So, the compressed picture may have a lack of original content.
Despite JPEG’s standard power to save comparatively high-quality images, the photos still have worse sharpness than the initial shoot. It especially refers to the pictures with sharp edges and a lot of details. They may become blurred and lose a professional look.
Designers know for sure that transparent and layered images are ultra-popular due to modern marketing trends. However, .jpeg standard doesn’t support such kind of pictures.
Face, barcode and fingerprints recognition software doesn’t work with .jpeg compressed images. It is not surprising, especially when mention how many pixels usually are being lost simultaneously with photo resizing. The object becomes distorted, so the algorithm couldn’t recognize it.
JPEG noise reduction software
The compressed JPEG image is going to be an appropriate solution while talking about the lightweight photo which fits most of the photo editing applications. For users who need a high-resolution image as well as a photo for object recognition purposes, other formats should be used.
However, having compressed the JPG image, the user may want to enlarge it as well. Besides, resized photos frequently have compression artifacts. These small pixels seem like sand in the user’s eye. So, image lovers should look for a reliable universal software that helps with jpeg repair as well as jpeg artifacts removal.
Image Upscaler for compressed JPEG repair
Image Upscaler supports JPEG format and may help to recreate lost pixels and add sharpness to the edges. This online tool allows uploading images with weight up to 5 Mb. The image can be resized up to four times!
Just visit imageupsaler.com, upload an appropriate picture and wait a few seconds. Get the magic done and enjoy the enlarged image. One of the main features of Image Upscaler refers to its possibility to remove artifacts from the photo.
Before – after using Image Upscaler
All you should do is upload a piсture with JPEG artifacts and click the acid green button nearby. After half a minute the user gets a spectacular image of high quality without any mess.
