TWAIN is an interface used to import from imaging devices, such as scanners. For more information, see the TWAIN Working Group's website at www.twain.org. The Photoshop TWAIN plug-in connects with compatible devices that are installed on your computer.

Note:

The TWAIN Plug-in provided on this page is NOT compatible with Photoshop CC 2015.5 and later on Mac OS.

Alternatives to using TWAIN

Due to limitations with TWAIN in Photoshop, we strongly suggest the following alternatives for scanning your images:

Use the stand-alone scanning software included with your scanner

Most scanners provide a stand-alone scanning application that can be used to scan and save images.

Using the stand-alone scanner software avoids issues associated with TWAIN. Using a dedicated application to scan allows you to retouch and edit images in Photoshop while you scan in the background – which can be more efficient.

If you use a stand-alone scanning application, save your scanned images as TIFF files, then open them into Photoshop.

Instructions: Scan and import images from a separate scanning application

Note:

Some scanner software lets you designate Photoshop as the external editor for an image after a scanning is completed. Consult the documentation that came with your scanner or contact your scanner manufacturer for more details.

Use a native OS scanning interface

Mac OS:

Use Apple’s ImageKit technology instead of TWAIN to scan directly into Photoshop. Support for ImageKit is built in to Photoshop without requiring a plug-in, and provides access to many scanners.

Instructions: Scan and import images using Apple’s ImageKit interface (Mac only)

Windows:

Use the WIA (Windows Image Acquisition) interface for your device, if it’s available, to scan directly into Photoshop.

Instructions: Scan and import images using a WIA interface (Windows only)

Note:

Contact your scanner manufacturer for more information on scanning using ImageKit or WIA.

Compatibility

Mac OS:

On Mac OS, Photoshop only runs in 64-bit mode. Not many scanner manufacturers have released 64-bit versions of their scanner drivers, so you may not be able to use TWAIN.

Windows:

TWAIN is not supported in Photoshop when it’s run in 64-bit mode. 

Note:

If you're on a 64-bit version of Windows, the 32-bit version is no longer installed by default. Download & install a 32-bit version of Photoshop.

Note:

Contact your scanner manufacturer for more information on compatibility.

Note:

Only use the TWAIN plug-in downloaded from this page. Do not use a TWAIN plug-in from an older version of Photoshop. (e.g. CS5 or earlier)

Download and install the scanner driver

Download the latest scanner driver from your scanner manufacturer’s website and install the driver.

Note:

Be sure to confirm the driver is compatible with the version of the Operating System on your computer.

Download and install the TWAIN plug-in

  1. Quit Photoshop.

  2. Download the Optional plug-in package:

    Mac OS:

    Windows:

  3. After you download the Optional plug-in package file above, double-click it to decompress it. If asked, extract all the files.

  4. Mac OS:

    Copy the TWAIN.plugin file to the Photoshop plug-ins folder:

    • Applications\Adobe Photoshop [Photoshop_version]\Plug-ins\

    Windows:

    Copy the Twain_32.8BA file to the 32-bit version of Photoshop plug-ins folder:
    • Program Files (x86)\Adobe\Adobe Photoshop [Photoshop_version]\Plug-ins\

    Note:

    If you're on a 64-bit version of Windows, the 32-bit version is no longer installed by default. Download & install a 32-bit version of Photoshop.

  5. Relaunch Photoshop.

Accessing your scanner from Photoshop

  1. Open Photoshop.
  2. Choose File > Import > [scanner name].

Note:

On Windows, ensure that you are launching the 32-bit version of by navigating to: Program Files (x86)\Adobe\Adobe Photoshop [Photoshop_version]\

Troubleshooting TWAIN

When you use TWAIN to import from an imaging device, you may encounter these issues:

  • Photoshop or your scanner application freezes or quits unexpectedly.
  • You are unable to close the scanner window.
  • You encounter errors during import.
  • The preview of the imported image, or the imported image itself, appears incorrect onscreen.

 

Try the following solutions:

Update the TWAIN driver

Download the latest scanner driver from your scanner manufacturer’s website and install the driver. Be sure to confirm the driver is compatible with the version of the Operating System on your computer.

Use a dedicated third-party scanning application

If your scanner manufacturer doesn't provide updated drivers that are compatible with current operating systems you may need to look at third-party scanning solutions. These third-party utilities are dedicated scanning solutions, and they are more appropriate for critical or high-volume scanning.

Third-party scanning utilities:

If you use a third-party scanning application, save your scanned images as TIFF files, then open them into Photoshop.
