What Type of File Do I Need to Order a Custom Wall Decor?

     Wallhogs is one of the very few digital format print companies that allow you to upload seven different image file types.  These are the most popular digital image files for both photos and professional artists that utilize some form of graphics editing program.  These file types breakout into two different formats; bitmapped/raster and vector - samples are displayed below.

Comparison Between Vector & Bitmapped Files

     Bitmapped images are the format most widely used and include file types with these extensions:  .jpg, .tiff, .png, .gif, .psd, .bmp and .pdf.  These file types are constructed of pixels where each pixel constitutes one color.  These millions of colored pixels are placed very close together to form the image.  As we’ve all seen when you enlarge a .jpg photo the pixels enlarge the more the image is magnified until you can see the color of each pixel.  However, the problem here is the more you magnify or enlarge the image you notice the pixels begin to blur – this is referred to as pixelization - as seen above. 

     If the image was saved at a low resolution the pixels will blur after just a few steps of magnification where files saved at higher resolutions will require much more magnification prior to pixelizing.  Wallhogs minimum accepted pixel resolution is 2048x1536, which is 3 MegaPixels (3MP) or three million pixels that construct the image (read at the end of the article on how to check your images resolution).

     For brevity sake we will only provide information on the file formats Wallhogs accepts.

  1. .jpg: This extension stands for Joint Photographic Experts Group and is the most widely used bitmapped image in the world.  Not only are the photos you take saved in this format, but many of the graphics you view online are in this file format.  The .jpg format allows for high compression in order to make the file a manageable size while still providing a high image quality.  This is one of the file formats you may upload to Wallhogs.
  2. .tiff: This extension stands for Tag Image File Format and is normally only available on hi-end professional photography equipment, in hi-res scanning and as file formats savable in professional graphics programs like Adobe Photoshop.  This image provides for a much larger file size due to the amount of color information provided in the header of the file.  These file types typically range in size from 35MB up to 3GB.  This is also one of the file formats you may upload to Wallhogs.
  3. .psd: This extension stands for Photoshop Document and is the default file type for the graphics program Adobe Photoshop.  This format allows you to save at various resolutions, however this program is expensive and not considered to be easy to learn.  Mostly used by professional photographers and artists.  This is one of the file formats you may upload to Wallhogs.
  4. .pdf:  This extension stands for Portable Document Format and is widely used for printed documents, however images may also be saved in this format from either the Adobe Photoshop or Illustrator graphics programs.  Wallhogs does accept tis file format.

     Vector based images are utilized by professional artists in programs such as Adobe Illustrator or CorelDraw.  This format is intended to be used for art or graphics rendering and not for taking photos.  File types associated with this format include:  .eps, .ai, .svg, .cdr and .pdf.  These files have an advantage over bitmaps due to their extremely small file size.  This is due to the files not requiring color information for each pixel – these file types are constructed of lines, curves and polygons, as well as mathematical formulas to produce the images you see onscreen.  No matter how much you enlarge these images they will never pixelate and maintain their smooth rounded edges - as shown in the comparison image above.

     Again, we will only provide information on the formats accepted by Wallhogs.

  1. .eps: This extension stands for Encapsulated Postscript and Wallhogs does accept this format.
  2. .ai: This extension stands for Adobe Illustrator and is exclusive to the Adobe Illustrator graphics program.  Wallhogs also accepts this file format.
  3. .svg: This extension stands for Scalable Vector Graphics and is most widely used in the CorelDraw graphics program.  Wallhogs does accept this file format.
  4. .pdf: This file format was explained above and can be ether a bitmap or vector image.

     This provide you a quick explanation of the file format Wallhogs accepts.  The vast majority of you will be uploading .jpg files and that is great – just make sure they meet our minimum resolution requirement of 2048x1536.  To check the resolution simply place your mouse cursor over the icon of the image without opening it.  Leave the cursor on the image and within a few seconds a box will appear providing you the pixel resolution.  You may also view the pixel resolution by place the mouse cursor over the thumbnail and right clicking once.  Select Properties from the dropdown menu.  Once the menu options select the Detail tab and the pixel dimensions are included there.
