Intro
Toolibex Image Compressor can assist in making image files smaller and easier to manage. Instead of working with big images that take space and time, you can use an image compressor that does it for you. We will explore the fundamentals of the process and how it applies to everyday tasks.
About the Toolibex Image Compressor
Toolibex Image Compressor is an image editing software designed to compress image files. This application is great for website maintenance, blog upkeep, graphic design, online business, and much more. It is utilized by website owners, students, bloggers, graphic designers, and online sellers.
An image compressor takes a file and reduces its footprint in terms of file size. This can be done in various ways depending on an algorithm used and an image type. The result is that your picture will occupy less space and be easier to upload, share, store, or publish.
Users may also call it a file compressor, photo compressor, picture compressor, compress image utility, or compressing application. All of these names refer to roughly the same application, but image compressor is a specific case applicable to photos.
Compression can be useful in a variety of situations. For instance, if you have an oversized picture that you need to upload somewhere, or you need to make your website faster. Image compressor can help with both.
Note that resizing an image is not compression. By reducing an image width and height, you alter its resolution, whereas compression alters the way a picture is encoded. However, they can be used together.
Image Compressor: How Does it Work?
Image compression works by altering an image in order to decrease the size of an image file. This process can be lossy or lossless, and the way it is done will vary depending on image type and chosen algorithm.
1. ### Open an image file
Any image compressor application works with a file, so you need to provide it with the image. Its size, resolution, color depth, and orientation can affect the outcome of compression. Note that larger and higher resolution pictures will have more data, so the result of lossy compression will be visibly different compared to a small photo.
2. ### Process your image
Once you have chosen the picture, the application you use will reprocess it. There are various algorithms, but all of them essentially remove data from an image in order to compress it. Some are lossless and only remove redundant information, some are lossy and discard less important information.
3. ### Smaller file
If the image compression has been successful, the resulting file will be smaller than the initial one. After you have processed the image, you will want to make sure that the result is still acceptable. In some cases, it may be necessary to retain some information, especially for pictures that contain important details.
4. ### Check your results
The most important thing before using the compressed image is to check that it is usable for your purposes. It may seem too pixelated and low resolution, or it may have some undesirable changes. When working with graphics or photographs that contain text, it is essential to make sure that it stayed readable.
How Much Did the Quality Lose? The Image Compression Fundamentals Explained
When you are compressing an image, you will have several factors to consider. First of all, you will want to see the difference between your initial picture and the resulting one. Secondly, it is essential to understand the changes that took place in order to ensure that the final image quality is acceptable.
File Size
When you are using an image compressor, you will want to know how much did the file size decreased. This information usually presented as “initial size – compressed size = saved space.” You can also see how much per cent the compressed image is smaller compared to the initial one:
Percentage reduction = ((Initial size – Compressed size)/Initial size) × 100
For example, if the initial picture was 4 Mb, and the resulting file is 1.6 Mb, the amount of saved space would be 2.4 Mb, or 60%. The actual size and the value of compression will depend on the picture, as some images compress better than others.
Quality Loss
When you compress an image, it is essential make sure that the final result is acceptable in terms of visual quality. Depending on an algorithm that you use (or lossy/lossless type), you will observe different changes. Quality loss can be especially prominent in the case of photographs, graphics with text, or some other images.
A good result of compression is when you do not sacrifice image quality for the smaller file size. It is always a good idea to keep the original image file, in case something went wrong during the process.
The final image quality is crucial when you are trying to preserve some important details. For example, you would want to decrease the file size of a background picture, as it is not as important as a photograph of a product. The latter should be compressed with more care in order retain image quality.
Image Dimensions
The dimensions of the image determine its resolution, which is essentially the amount of pixels contained within a picture. It is usually measured in width × height, such as 2400 × 1600. Lowering the resolution will decrease the file size, and you might want to consider doing that as well.
However, image compression and reduction of resolution are two different things. Some applications allow you to do both of these, but it is recommended to adjust the size yourself in accordance with your needs.
Format
JPEG, PNG, and WebP are three of the most popular image formats, as each of them uses a different method of compression. The type of image will also affect how useful it is (for instance, you cannot transparent PNG images as easily). Most tools only offer a selection of several image formats that are available in the tool.
Image Compression Examples
Make Website Images Smaller
If you are running a website or a blog, you probably want to optimize your images. Large images take up too much space and slow down the website, so it is a good idea to make them smaller and faster to load.
For example, pictures on blogs would be perfect for using an image compressor. Once you process them, you will have smaller files that will be faster to load. At the same time, the quality of the image should still be sufficient to see what the picture is about.
Compress Photos for an Online Store
Most online stores carry multiple products and they usually have multiple pictures for each. It is important to make pictures as small as possible in order to keep the website fast. At the same time, images should still be of sufficient quality and contain all the necessary information.
This applies to all types of pictures: product photos, graphical elements, and even text. Once you have compressed the picture, make sure to check the details to ensure that everything is still visible.
Compress Photos for Email
Some email services and online applications only allow you to upload images that are below a certain size. A good image compressor can help you to decrease an image file size without lowering the quality of the picture.
This way, you will not have to reduce the resolution of an image just to make the file smaller.
Compress Images for Messenger
If you want to send large photos through messengers, you will have a problem. This is especially true for applications such as WhatsApp, where all images are automatically compressed. However, if you have an image compressor you might be able to achieve better results.
You can compress an oversized picture and send it as a message or an attachment. Alternatively, you could also consider resizing a picture if you need to send a set of them.
Optimize Graphics and Screenshots
Screenshots, graphics, and illustrations often have different compression requirements. Usually, they have larger amounts of text and/or graphical elements. This means that you should be more careful when compressing them.
Lossy types of compression will make text unreadable, which is not acceptable for such images. It is better to use lossless compression algorithms or decrease the resolution instead.
Tips
There are several things to consider when compressing images. First of all, make sure to keep your original image. This way, if something goes wrong, you will be able to restore it. Another thing to consider is that different pictures have different needs.
For example, pictures for website may require smaller size and lower quality, whereas graphics and photographs will need to be treated with more care. You should also avoid unnecessary lossy compression as it will accumulate with each step.
If your image has a very large dimension, it is probably a good idea to decrease it as well. However, always make sure that the resolution of the picture will be sufficient for your needs. Lastly, choose a suitable format for your picture. It is usually easiest to work with JPEG and PNG image formats.
FAQ
1. What is an image compressor?
An image compressor is an application that reduces the file size of image files. It can be used to make photos take up less space, be faster to load on a website, or easier to send from one person to another.
2. Is an image compressor the same as a file compressor?
An image compressor only compresses image files. File compressor or file optimization application usually compresses multiple files at a time. They can work with documents, spreadsheets, text files, and more.
3. Does compressing an image reduce its quality?
Not always. Lossless compression does not reduce the quality of an image, as it only removes redundant information. Lossy compression, on the other hand, will always result in some data loss. The degree to which the quality of an image will be affected depends on the algorithm and the contents of the picture.
4. How can I compress an image without losing quality?
You can compress an image without losing quality by using lossless compression methods. If you are using an application that allows you to choose between different compression algorithms or modes, select the one that does not alter the quality of an image.
Make sure to compare the compressed image with the original file to ensure that nothing has changed.
5. Does image compression decrease resolution?
Not always. Compression alters the way in which a picture is stored, whereas resolution determines the amount of pixels in an image. However, there are applications where you can choose to compress an image and decrease its resolution at the same time.
6. What is the difference between a photo compressor and a PNG compressor?
A photo compressor is an application that compresses photographs. A PNG compressor compresses pictures in PNG format. Usually, you would want to open a photo compressor if you want to alter the type of compression, whereas a PNG compressor would be used to remove excess data.
7. Is Toolibex similar to TinyPNG?
TinyPNG is another image optimization application. Similar to Toolibex, it allows users to compress images. However, there may be some difference between the two, and you would want to choose the one that is most suitable for your needs.
8. Why is my compressed image still large?
Depending on the type of image and the algorithm of compression, some pictures will not be significantly affected by the process. They may already be compressed by default or contain too much data to be removed by a lossy compression method.
9. When should I compress an image?
You should compress an image before publishing it online, sending it through email, or uploading it elsewhere that requires a file to be below a certain size. Always check the image to ensure that it still meets your standards.
