File Types and Extensions

Learning Center

File extensions are the three-digit letters you see at the end of a file name such as (.jpeg, .pdf, .gif, . tiff) File extensions indicate what format the file has been saved in.


JPEG (Joint Photographic Experts Group) file format holds a high degree of color and uses less storage space on hard drive than needed for other file formats. Uncompressed JPEG files can be used for high-quality printing. JPEGs are used for photographic image files and save a lot of space when placed on the web. Please ensure that submitted JPEG files are at least 300 dpi or the printed product will look blurry. A better way to send artwork is to use Adobe PDF Job Ready.

EPS (short for Encapsulated Postscript) file format stores files as vector points and include low-resolution bitmap representation for a quicker on-screen viewing. For 1 or 2 color jobs we prefer getting eps files.

PSD (Photoshop Document) is a saved file format when using the Adobe Photoshop design program. A PSD file is considered a source file and retains editability. PSD is the only file format that supports all available image modes (Bitmap, Grayscale, Duotone, Indexed Color, RGB, CMYK, Lab, and Multichannel), guides, alpha channels, spot channels, and layers. If you saved it as a JPEG, you might not be able to edit the layers because as a JPEG, it will flatten the layers before you save the document.

*Please ensure that submitted PSD files are flattened before saved and uploaded. Save PSD files with flattened layers as well as original file containing un-flattened layers for editing purposes.

TIFF (Tagged Image File) file formats are used for storing images on a computer. Please make sure submitted TIFF files do not contain any compression and are high resolution (at least 300 dpi). Print Papa prefers TIFF files for full color jobs in 300 dpi resolution.

PDF (Portable Document Format) is a file format that allows any file to be read or viewed by Acrobat Reader. PDF can be created by most of the Adobe design application like Illustrator, Photoshop, In-Design, Acrobat Professional.

There are also lots of 3rd party utilities which act as add-ons to other application and provide the conversion to PDF. Please be careful that the final converted PDF might not be suitable for printing. If you don't have Acrobat Professional to create PDF then we would recommend downloading and installing our Adobe PDF Job Ready Driver to create print ready pdf right on your desktop, then proof it and send it to our servers in few clicks.

Note: If you have Adobe Acrobat Professional installed on your computer and you are printing to PDF then please make sure to change the setting from Standard to Press Quality by going to properties.
