In computing, JPEG (named after the Joint Photographic Experts Group, which created the standard) is a commonly used method of lossy compression for photographic images.
The file format known as JPEG Interchange Format (JIF) is specified in Annex B of the standard. However, this “pure” file format is rarely used, primarily because of the difficulty of programming encoders and decoders that fully implement all aspects of the standard and because of certain shortcomings of the standard:
Color space definition
Component sub-sampling registration
Pixel aspect ratio definition
Image files that employ JPEG compression are commonly called JPEG files. Most image capture devices (such as digital cameras) and most image editing software programs that output JPEG files are actually creating a file in the JFIF and/or Exif format．
The most common filename extensions for files employing JPEG compression are .jpg and .jpeg, though .jpe, .jfif and .jif are also used. It is also possible for JPEG data to be embedded in other file types - TIFF encoded files often embed a JPEG image as a thumbnail of the main image.
Do you have a large sequence of JPEG images and would like to create a time-lapse movie out of them? Luckily, you can try a program called PhotoLapse to do this.
PhotoLapse is a free portable tool for Windows that can create a movie in avi format from large sequence of jpg images. All you have to do is to browse the directories where the images are located and add them to the list. Next, you can check/uncheck the images that you would like to include/not include in the video. You can also mark every 2nd, 3rd, or any number of frame, which makes it easier to include less images in the video, thus saving the total video size.
Apart from the basic settings, you will find 3 additional options: Check for errors when loading, selecting the video FPS, and option to create a reverse movie
Once you are all done, hit Create Movie, and choose the location where you would like to save the video.
A .JPEG file is an extension type used to identify photos on a hard drive. It is one of the more commonly used photo file types on the Internet for the purposes of uploading, editing and duplicating photos. Creating JPEG files creates ease of access and gives you the ability to alter a photo however you like. These instructions will teach you how to take photos from the Internet and save them as .JPEG for your personal collection.
Choose the photo you would like to save. Right-click on the photo and choose Save Image As....
A Windows Explorer dialog box will then appear, prompting you to choose a location where you would like the photo file to be saved. In most cases, your Pictures folder will be the default location for these types of files. Click Save.
Now click the Start Menu or Start icon located on the desktop taskbar. Click My Documents. When the Windows Explorer dialog box appears, you will see several personal folder icons. Click My Pictures. The photo file you saved should be located in this folder.
Right-click on the photo. Go to Open With and click Choose Programs.... (Depending on your computer and operating system, this prompt option may be worded differently.) Click Paint.
When Microsoft Paint opens, the picture should be loaded in the program.
Go to the option bar located at the top of the program and click File. In the File drop box, click Save as and the Windows Explorer dialog box will appear.
Click on the dropbox located under the name of the picture, and you will see a list of file type extensions that the photo file can be saved as. The JPEG extension will be listed.
Click the JPEG extension and click Save to permanently change the photo's file extension. Do not alter the file's location. This will allow the file to be placed back into its original folder under the new extension. The program should automatically close when you save the file.
Image Converter Plus can convert files into JPEG format. There are lots of formats, but JPEG is the most popular one.
Image Converter Plus is a powerful tool designed to optimize file conversion process. Usually, users may need 3 to 5 conversion presets at home and more in office. These presets may include: "Conversion to jpeg format with 128x128 size", "Conversion to jpeg format with 90 degrees rotation".
It's very easy to create and use profiles in Image Converter Plus. You can also save your profiles and use them in your future work. Image Converter Plus dramatically reduces the amount of time it takes to convert files.
Use right-click conversion together with your profiles to achieve best result in shortest possible time with minimal effort. This approach lets you concentrate on your main tasks and makes file conversion a ast and painless procedure.
Below you can learn how to convert your files to JPEG format.
Launch Image Converter Plus from Windows main menu.
Here's a screenshot of Image Converter Plus user interface.
Select JPEG format as target format.
Expand Save images in JPG format group and adjust any needed settings.
Note: Available color depth is 8, 24, 32 bits. Compression quality depends on image quality parameter. Use the slider to specify a value from 25% to 100%. 100% quality preserves original image quality. more >> link expands to a professional set of JPEG parameters. You won't need this section for daily usage:
Extra JPEG settings feature saving EXIF and IPTC information. EXIF and IPTC are usually present in photos created with digital photo cameras.
There are a number of software programs that can convert a jpeg into a vector image. Most of the programs are either very expensive, or much less expensive with a limited capacity for reproducing colors.Here is a fairly simple method that uses an open-source freeware program with the capacity to handle color images.
Download Inkscape. After clicking download, click Run to have the program installed on your computer. The default folder it chooses is usually OK to install it into. After installation, select Open Program to begin.You will not need to learn very much about the program to make a vector conversion. The function is mostly automatic, with a few options available that you can use to preview the image.
In the menu bar at top. select File, then Import as pictured in the screenshot here. This action will enable you to place your JPEG file in the document prior to using the conversion function.
Browse your folders to locate the JPEG file you wish to convert to a vector image. Select the image file and click OK. Your image should appear in the center of your document as pictured in the screenshot here.
Go to the menu bar at top and select Path then click on Trace Bitmap. This action will open a window that will allow you to adjust some settings and preview the image on the right.
Select the radio button option for Colors on the lower left as pictured in the screenshot here. Then increase the number of Scans a few times. and click on the bar labeled Update below the preview image. Raising the number of scans give you increasing resolution of the image, which also increases the file size and speed of rendering. Experiment with the settings to find what works best for your purpose with your computer's capacity. Remember to click Update each time.
Save the image as one of the vector image formats provided. An .eps file is a good choice for most applications. You have successfuly converted a JPEG image to a vector file.
The JPEG or JPG file extension represents a standard type of digital image file. These image files are compressed to save space on a hard drive, but are also of a very high visual quality. If you want to open a JPEG file on your computer, you don't need to download a program. Your operating system already comes with a program that will allow you to open these files.
Locate the JPEG image file you'd like to open. JPEG files can have both a .jpeg and .jpg file extension. If you do not already know the location of the file on your computer, you can locate it quickly by clicking on Start and then Search.
Right-click the JPEG file.
Click Open With>>>Choose Program....
Click on the name of the program you'd like to use to open your JPEG image file. If you just want to view the image file, click on Windows Picture and Fax Viewer.
If you'd like to both view and edit your image, click on Paint.
