Quality digital image may be large in file size. Usually photos taken from high resolution digital camera can have very large file size (hundreds of KB or sometimes in MB too). Even picture files obtained from scanner after scanning are also large in size. It is problematic to upload such large image file online due to the huge file size of the digital picture. Before the image file is uploaded, reducing the image file size into less KB can be a solution to these types of optimization problems.
Why Digital Image File Resizing is Necessary
There are several reasons behind reducing image file size in less KB before you upload any image file online:
- Nobody likes big images as it takes lots of time for downloading and eat unwanted internet data usage.
- Some websites prevent uploading large-sized image file. So upload quality images with decreased filesize. For this you need to convert image files into smaller file size pictures.
- Many websites pre-set the maximum filesize limit for digital images | pictures. For Example, to upload your photo, some websites instruct you to upload the image file up to a limited size (such as maximum 50KB, 100KB, etc.) while filling online application forms.
- Certain e-Mail provider sites have file size restriction for mail attachment. So, before attaching huge image file one has to first reduce its filesize.
- Social networking websites like Google Plus, Facebook, Orkut like small images as they can be uploaded | downloaded quickly and efficiently.
- Even if you and your friend have fast internet connections, you should always upload compressed | resized image files for fast optimization purpose.
- Attaching large image file will require more time for uploading.
- Bloggers running sites having greater page views should always think about reducing image size as this will save their image bandwidth thereby keeping their bandwidth usage under certain threshold.
- If you are developer, designer of any website, you have to care the image files you would be adding to your sites. Because users like quality images but reduced filesize for faster browsing.

Basic Tips | Tricks to Reduce Image FileSize
Digital image file formats are GIF, PNG, BMP, JPG, JPEG, JPE, BMP, DIB, RLB, EMF, TIF, TIFF, JIF, JIFF, RAW, PPM, PGM, PBM, PNM, etc. Out of hundreds of digital image file formats available, only PNG, JPG and GIF formats are the most widely used formats to display images on the Internet. You should know where to use these popular image file formats such as GIF (Graphics Interchange Format) or JPG|JPEG (Joint Photographic Experts Group) or PNG (Portable Network Graphics) correctly for better performance. Delivering images with minimum filesize and least download | upload time has always been choice of every webmaster. So, you can observe these simple basics to generate reduced file-sized quality images for internet use.
While editing JPG images, you should avoid saving the file again and again as every time you saving the same image file reduces the image quality. This is why JPG image is known as lossy image file format. The better way to edit JPG images is to edit | make all the changes you want and finally save the image file with a new | different file name. So we have seen it that understanding the usage of the three widely used image file formats (GIF, JPG and PNG) is most important for managing image file sizes without affecting the quality.
Where and How to Use GIF, JPG and PNG Image Formats
- GIF Image Files: If there are large areas of uniform color and the total number of colors is less than 256, GIF images are preferred for creating images of less file size. For computer generated images (such as line drawings, text logos, black and white images and small text with few pixels high, etc.) with limited color palettes GIF file format are used. GIF graphics is not suitable for photograph or complex graphics. GIF image format is a lossless compression technique. GIF images are usually less in filesize. Two or more GIF images can be put together with an animation editor for creating animated images.
- JPG | JPEG Image Files: For displaying photograph or complex graphics image JPG | JPEG file format is used because JPG images support 16 million colors. JPG graphics is not appropriate for line drawings, simple graphics or text logos. JPG image format is a lossy compression technique. JPG image filesize is larger for higher image quality whreas the filesize is smaller for lower image quality. If you select JPG image format you have to compromise on either the quality of the image or the size of the file.
- PNG Image Files: PNG image is newer format i.e. improved version of the GIF technique and currently supported by major web browsers. PNG image format uses ZIP compression. A PNG format image file is, in general, 5% to 25% more compressed than a GIF format image file of the same image. PNG format is a lossless compression technique. PNG graphics can be used for any type of images such as photographic images, quality photos, graphics, text logos, line art etc. Hence, PNG file format can be undoubtedly used for unquestionable best quality graphics. Unlike GIF format, the PNG image format does not support animation. However, for general purpose graphics file, PNG format is excellent.
While editing JPG images, you should avoid saving the file again and again as every time you saving the same image file reduces the image quality. This is why JPG image is known as lossy image file format. The better way to edit JPG images is to edit | make all the changes you want and finally save the image file with a new | different file name. So we have seen it that understanding the usage of the three widely used image file formats (GIF, JPG and PNG) is most important for managing image file sizes without affecting the quality.
