Five free graphic photo editors. Programs for working with JPEG

There are many different ways how to change image format. The file format determines in which program it can be opened or edited. The file extension defines this format. Most people who work with images will find themselves needing to convert those files to another format at some point, so it's worth exploring a few different ways to do this. JPEG (aka JPG) is the most commonly used image format.

Method 1: Using Image Editing Software

1. Open an image file. When you need to convert an image to another format, the easiest solution is to use the image editing software included with your operating system. On Windows it is " Paint", and on Mac - "Preview":

• Note that JPG and JPEG are different names for the same file extension;
• You can also use third-party programs to open the image file. If you're not sure, try double-clicking the image to open it with the default program for that file type:

1. Before changing the image format to jpg, select "File" in the main menu. A drop-down menu of options for the image should appear on the screen:

1. Save or export the image file. The format change will occur simultaneously with the saving of the new version of the file. This is useful: the original file remains unchanged, and if something goes wrong, you can always return to it. On a Mac, you need to select “Save as” or “Export” to continue the process:

• In some versions of the software you will need to first "Duplicate" the file ( that is, make a copy of it), and then “Save”. This way the file will be saved in a new format:

1. Change the file name and extension. In the window that appears, you can change the name as well as the extension (format) of the file. In the "Format" or "Save As" drop-down menu there should be about 12 options, including " .jpeg«:

• Before changing the image format to png, change the file name or location if necessary. For example, you can place it on your desktop for quick access;
• If the extension you need is not in the drop-down menu, try a different image editing software ( for example Photoshop):

1. Save the file. After you specify the desired file name, extension and location, click the "Save" button. This way you will convert the file to a new format while preserving the original:

• Software such as Preview can batch process file conversion. To do this, select the files that need to be converted and right-click on them to see the available options.

Method 2: Using Third Party Software to Convert Images

1. Find the software you need. Graphic editors are quite suitable for converting images into the most common formats. You can also search for suitable software on the Internet:

• For example, for the queries “ doc to pdf" or " jpg to gif"We find several online converters at once.

1. Upload image files. Most online image reformatting services offer their services for free and do not require downloading software to your hard drive. First of all, pay attention to services that offer instructions for downloading and converting files:

1. Follow the instructions. Sometimes these sites will ask for an email address and then send the finished file to you at that address once the conversion is complete. In other cases, you need to wait a few seconds and then download the finished files:

• Beware of sites that ask you to pay or provide personal information. Remember: there are many free services where you don't need to provide anything other than your email address.

Method 3: Converting Images on Mobile Devices

1. Before you change the image format on your computer, check out the mobile apps available for installation.. Before downloading, be sure to read reviews to determine the quality of the application and ensure that the software you choose will convert the files to the formats you need.
2. Download an image converter app. Once you have selected the appropriate application, download it. You also need to upload an image file ( if you haven't done so yet) and remember where it is. Some applications can detect images automatically, while others require you to specify the required files.
3. Convert images. After installing the program on your mobile device, you need to open the application and follow the instructions.

Method 4: Manually change the file extension

1. Find the file. For graphic files, you can change the extension manually by changing the file name using the keyboard. This is the correct solution if the file's current extension prevents you from accessing its contents ( I get an error message "invalid file format"):

• The computer uses file extensions to figure out what software to open the file with. Be careful when changing extensions manually and always save a backup before doing so;
• Before you change the image format, you need to understand that this method may result in reduced image quality. Using image editing software is usually a more suitable method.

1. Make the file extension visible. Depending on specific settings, file extensions ( three letters after the dot in the file name) may not be visible to the standard way of viewing files. In the Windows operating system, you can configure the corresponding settings on the “View” tab in the “ Folder Options” section. It is located in the " Appearance and personalization options" On a Mac, these options are set under " Additional search settings»:

1. Rename the file. Right-click on the image file and select “ Rename". Remove the old extension and add a new one.

For example, if the file name is " myimage.png", you can rename it to " myimage.jpg“, and from now on your computer will see it as a file in the “.jpg” format.

Questions and answers:

How to convert images from PNG to JPEG?

How to change the image format on a computer? " Paint" or " MS Paint"is a simple image viewing and editing program included with the Windows operating system. Open the PNG file in Paint and then use File>Save As save the file in JPG format. If you're on a Mac, you can use iPhoto. Open the PNG file in iPhoto, then go to File > Export and select JPG from the list.

How can I convert .avi to .jpeg?

Avi is a video format and jpeg is an image format. You first need to take a photo of a frame of the video during playback and then save the image as a jpeg.

• The extensions .jpg and .jpeg mean the same thing and can be used interchangeably in modern operating systems. This distinction comes from the early standards of some systems, in which only a three-letter extension was allowed;
• File extensions are not case sensitive, although common convention is to use lowercase.

Conclusion

Don't replace the original image - always back it up or use the "Save As" method.

Good bad

Working at a computer every day, we deal with a lot of graphics. This seems so familiar and natural that even the simple question “what is the first graphic image that appears after turning on the computer?” many would answer that it is the Windows logo, without paying attention to the BIOS logo. A huge number of formats have been invented to display graphics on the screen. We think it would not be a mistake to say that the largest number of images are recorded in the JPEG graphic format. Every time you load pages in Internet Explorer or another browser, photographs and drawings appear on the screen, which are files with the JPEG extension. Almost all modern digital cameras save pictures in this format. The reason for the high popularity of the JPEG standard is obvious - the small size and high quality that can be achieved when saving graphics in this format. At the same time, the size/quality ratio of JPEG is almost always better than that of any other graphic format. The name of this format stands for Joint Photographic Experts Group. This is the name of a commission composed of representatives of the standardization organizations International Telecommunications Union (ITU) and the International Organization for Standardization (ISO) and organized specifically to develop a method for compressing images. To create JPEG images, many people use cumbersome raster graphics editors such as Photoimpact, Photopaint, Photoshop and others. However, if your main activity is preparing images for the Internet, you can get by with a set of small utilities designed specifically for saving pictures in the JPEG format. On the one hand, this will save the cost of purchasing software; on the other hand, they are easier to learn than serious graphic editors, and often have more specialized tools.

Unjpeg has different profiles to address varying degrees of artifacts. The program settings can be divided into two main groups: those responsible for removing sharp transitions between blocks, and filter settings for focusing. In addition, the program contains two methods for searching for artifacts in an image: a heuristic artifact detection algorithm and a standard image analysis method using information in the JPEG file header. The search for artifacts will also differ depending on the type of image - whether the file is a poorly saved drawing, or a poorly compressed photograph.

Unjpeg also has an additional filter to remove random noise. The only drawback of the program is that the rollback function only works for the anti-noise image filter. The program is distributed as shareware. The demo version can be downloaded from the official website.
