  • Digital images fill up our inboxes, take up computer memory space and take time to load on a web page. When working with digital image files there are certain file types to use for each circumstance.

    JPEG

    File extension: .JPG or .JPEG

    “JPEG” stands for “Joint Photographic Experts Group.”

    The group designed the format in 1986.

    Pronounced “jay-peg”

    16-bit data format

    Can display millions of colors

    Uses a very complex compression algorithm

    To reduce file size

    Let image details be “forgotten” and then fill in when displayed

    Called “lossy” compression for the lost data

    The human eye doesn’t see color detail as well as it does light and dark detail, so some color detail can be sacrificed to save file space.

    60-75% compression is usually optimal for website usage.

    Use when a small file size is more important than maximum quality

    Standard file format of digital cameras and web pages.

    Compatible across many platforms (PC and Mac), and other programs (web browsers and image editors).

    In March 2014 Mozilla createdthemozjpeg format.

    Works within the current, recognizable jpeg format.

    Works with existing platforms, such as web browsers.

    Reduces the file size up to 15% more without losing quality.

    Useful for web pages, especially Facebook, for faster upload.

    JPEG Mini Tool

    Tools like JPEG Mini let you compress photos up to 5 times without losing quality.

    Smaller file sizes means less storage space needed and quicker upload.

    Best Uses:

    Still images only

    Real-world images like photos

    Complex coloring

    Shading of light and dark

    PNG

    File extension: .PNG

    “PNG” stands for “Portable Network Graphics”

    Designed in the mid-1990s as a way around patent issues with the GIF format, including benefits from both GIF and JPEG.

    Pronounced “ping” or “P-N-G”

    Lossless compression, so no data loss.

    PNG-8

    Very similar to GIF

    256 colors and 1-bit transparency

    PNG-8 files are even smaller than GIF files

    PNG-24

    24-bit color, similar to JPEG

    Can include over 16 million colors

    Lossless compression means larger files than JPEG

    Alpha-channels

    PNG files allow transparency to be set on a scale between opaque and completely transparent, allowing for a faded, translucent look.

    PNG images can be put on any color background and maintain original appearance

    Some older browsers may have trouble supporting PNG files because of alpha-channels.

    Best Uses

    Web images such as logos that involve transparency and fading.

    Images in the middle of the editing process.

    Complex images like photographs if file size is not an issue.
