Keeping proportions

Online JPEG Converter is designed to convert your image files to JPEG.

Convert PNG to JPG, EXR to JPG, ARW to JPG and more 250 image formats. A full list of image formats you can find here.

We also support many RAW formats.

In JPG settings you don’t see some of your settings, this is due to fact that they are not available at specified combination. Changing type of compression you can get more options, or some of them will change. For example, if compression «lossless» you can get color depth 64 bits!

It should also be borne in mind – using a flexible configuration, you can retrieve a file that will not display standard viewers. This does not mean that you have received wrong file. Try to use alternative means for viewing.

We support convert progressive JPEG.

More info about output format: JPEG (Joint Photographic Experts Group).

Use of JPEG format

The compression algorithm was created specifically for the transmission of digitized images over digital communication networks. It is convenient to send pictures, text and pictures with text to JPEG. When compressing, small losses of detail are inevitable, the quality deteriorates slightly, primarily due to a given level of quality. The higher compression, the greater loss.

JPEG is one of main formats used on Internet for more than 30 years. Its competitor in network is PNG, which compresses without losses, and even allows you to maintain transparency. JPEG is convenient for posting photos on websites, forums, social networks. Pictures do not overload server, do not slow down loading of pages, which helps owners of Internet projects to save traffic and do not lose impatient customers who leave the pages irritated with slow loading.

All professional digital cameras, tablet or smartphone cameras are able to save images in JPEG. Photo processing is much faster than in RAW. This is useful when shooting a series of reports about sports or nature – speed of photography and number of shots taken per second. It should also be noted that the file size in JPEG is smaller than RAW formats, such as CR2 or NEF. A list of RAW formats can be found on our website.

JPEG advantages

Popularity of JPG is explained by fact that files with this extension can be easily opened on any device where there is an option to view: computers, TV, gadgets. Its universal encoding algorithm is easily recognized by browsers, graphics editors and photo managers, OS viewers and third-party viewers. JPEG files can be used with MacOS, Windows, Linux or mobile operating systems.

Advantages of JPEG, thanks to which it is widely used to save images:

  • Different variants of color depth support from 8 to 32 or even 64 bits, depending on chosen compression algorithm.
  • You can save a picture created or edited in many programs: Paint, Photoshop, AutoCAD, Gimp, Corel.
  • Maximum allowable side size is 65535 pixels.
  • Compression in ranges of 10:1, 20:1 occurs with high speed.

Even if you don’t have complex graphics programs on your computer, any image can be easily transferred to JPEG. Add this page to your bookmarks and use our JPG converter. 

Shortcomings in JPEG format

  • JPEG format in lossy compression mode is not suitable for compressing drawings, text and character graphics. It is caused by that sharp contrast between next pixels leads to occurrence of appreciable artifacts and it will lead to that subsequent processing of such images, for example, conversion of image in 1-bit TIFF will be unreadable. Therefore, it is advisable to save such images in formats without loss, such as TIFF, PNG or use Lossless compression mode for JPEG. By way, you can choose Lossless compression in our service, but you should take into account that in this mode file size will be larger than in normal compression.
  • JPEG (as well as other lossy compression formats) is not suitable for compression of images, which are planned to be used for further processing, as distortions in images will be introduced every time you save intermediate results.
  • If you choose Lossless compression, you may encounter a problem that not all viewers will be able to display your image, as this format is quite rare and not all manufacturers support it. Currently, its use is quite specific and it is mainly used for astronomy and medicine, where you can’t afford to lose any information.

Comparing with other formats

In JPG you can save a screenshot, a video frame, a photo from a webcam, in general any graphic information. Even beginners can easily work with jeepeg files – trim, resize, change size, contrast or color saturation.

In demand it is comparable to PNG – format recognizes and supports 16 million shades, well stores and transmits brightness of color rendering in a compressed form.

It is more difficult to work with other extensions:

  • SVG – refers to text formats. Stores 2-dimensional vector and mixed raster-vector images created on the basis of XML. Supports regular and animated graphics. At scaling remains without quality loss.
  • CR2 – uncompressed image (RAW), which format is based on TIFF. With this extension, photos created with Canon cameras are saved. Pictures are saved in the same format as they were taken and require a lot of storage space.

If you need to compress CR2 or image files with any other extension, it is more profitable to use the converter than to search, download and install the appropriate editor on your computer.

Converting

Many graphics formats are designed for a particular program, so not all third-party applications are able to recognize and open them. In such cases, a JPG converter is indispensable. We suggest that you use the features of our JPG Converter service to translate your images, for example: PNG to JPG, CR2 to JPG, SVG to JPG.

The JPEG converter contains basic settings that you can use in JPEG format:

  • the depth of color;
  • the required percentage of quality;
  • one of four types of compression;
  • subsampling;
  • create thumbnail;

You can set the DPI, new dimensions in pixels. Or give a command to delete EXIF technical data. They can be used to easily determine the type of camera, settings, and time to take the picture. IPTC information will reduce the time required to upload and create files on photobanks’ websites. This is convenient for those who earn money by selling photos at the photostocks.

If you need to get a vector image, we offer you to convert raster files with the help of a convenient tracer. There are 3 different ways to convert a raster image to vector one with different settings on this site.

Compare JPG, PNG, CR2

Format introductionJPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality.Portable Network Graphics (PNG) is a raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for Graphics Interchange Format (GIF), and is the most used lossless image compression format on the Internet. PNG itself does not support animation at all. MNG is an extension to PNG that does; it was designed by members of the PNG Group.The .CR2 file format (Canon RAW version 2) is a digital photography RAW format created by Canon. “RAW” here means that this file stores information directly coming from the sensor, almost without processing. RAW files can be seen as a digital negative format, and do not contain a “ready to view” picture, like jpeg.
Technical detailsImage files that employ JPEG compression are commonly called “JPEG files”, and are stored in variants of the JIF image format. Most image capture devices (such as digital cameras) that output JPEG are actually creating files in the Exif format, the format that the camera industry has standardized on for metadata interchange.PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without alpha channel), and full-color non-palette-based RGB[A] images (with or without alpha channel). PNG was designed for transferring images on the Internet, not for professional-quality print graphics, and therefore does not support non-RGB color spaces such as CMYK.RAW file is the best quality/size ratio storage a photograph can use to store his picture, mainly because each primary color (R, G or B) is recorded in 12 or 14bits (8bits for Jpeg), and a lossless compression is used (lossy for Jpeg). Jpeg files on the opposite are “ready to use” files, but a lot a processing is necessary to obtain such file, it is made automatically by the Camera embedded software.
