The error means Photoshop ran into a problem it couldn't solve on its own

When Photoshop displays "Could not complete your request," it is telling you that a specific action — opening a file, explore a filter, saving, or exporting — failed partway through. The message is vague because Photoshop encountered an internal error rather than a clear problem it can name. The actual cause is usually one of five things: the file itself is corrupted or in a format Photoshop cannot read, your computer ran out of memory while processing, a plugin or extension is interfering, the file permissions are locked, or Photoshop's cache has become corrupted.

The error appears most often when working with large files, explore complex filters, or using older file formats. It can also happen when you try to open a file that was damaged during read or transfer, or when a plugin crashes mid-operation. Unlike a message that says "file not found" or "out of disk space," this error does not tell you which of these problems you are facing, so you have to test them one at a time.

Key Takeaways

  • The error usually means Photoshop ran out of memory, encountered a corrupted file, or hit a plugin conflict — not that your computer is broken.
  • Restarting Photoshop and clearing the cache folder solves the problem in most cases.
  • If the error happens with one specific file, that file is likely corrupted and you should try opening a backup or re-downloading it.
  • Disabling plugins one at a time can identify whether an extension is causing the crash.
  • Increasing Photoshop's memory allocation in preferences can prevent the error when working with large images.

Restart Photoshop and clear the cache first

The fastest fix is to close Photoshop completely, wait ten seconds, and open it again. This clears temporary files from memory and resets Photoshop's internal state. If the error happens again, close Photoshop and delete the cache folder. On Windows, navigate to C:\Users\[Your Username]\AppData\Roaming\Adobe\Common\Media Cache Files and delete everything inside. On Mac, go to ~/Library/Caches/Adobe/Common/Media Cache Files and do the same.

After clearing the cache, open Photoshop again and try the action that caused the error. The cache folder will rebuild itself automatically. This solves the problem in roughly half of all cases because Photoshop sometimes writes corrupted temporary data that it cannot read back. If the error persists, move to the next step.

Test whether the problem is the file itself

Open a different image file — one you know works — and try the same action that failed. If it works on the other file, the problem is with the original file, not Photoshop. Try opening the original file in a different program: if it opens in Preview (Mac) or Photos (Windows), the file itself is readable but Photoshop cannot process it for some reason. If it will not open anywhere, the file is corrupted.

If you have a backup of the corrupted file, use that instead. If not, try re-downloading it or asking whoever sent it to you to send it again. Files can become corrupted during email transfer, cloud sync, or if your computer shut down unexpectedly while saving. If the file is critical and you have no backup, a data recovery service may be able to restore it, but that is expensive and not always successful.

Increase Photoshop's memory allocation

Photoshop needs enough RAM (random access memory) to hold the entire image plus all the layers, filters, and undo history. Large files or complex operations can exceed what Photoshop is allowed to use. Go to Photoshop > Preferences > Performance (Mac) or Edit > Preferences > Performance (Windows). Look for the "Memory Usage" section and increase the percentage allocated to Photoshop. If it is set to 50 percent, try 70 or 80 percent.

Do not set it to 100 percent — your operating system needs memory to run itself. If you have 16 GB of RAM, setting Photoshop to 75 percent gives it about 12 GB, which is usually enough. If you have 8 GB or less and work with large files regularly, the error will keep happening until you upgrade your RAM or work with smaller images. After changing the setting, restart Photoshop for the change to take effect.

Disable plugins to find conflicts

Third-party plugins — filters, extensions, or tools you installed — can crash during operation and cause this error. Start Photoshop while holding Shift (Windows) or Shift + Option (Mac). This launches Photoshop without loading any plugins. Try the action that failed. If it works, a plugin is the problem.

To find which one, go to Photoshop > Preferences > Plugins (Mac) or Edit > Preferences > Plugins (Windows) and disable half of your plugins. Restart Photoshop and try again. If the error returns, the problem plugin is in the half you disabled. If it does not, the problem is in the half still enabled. Keep splitting the remaining plugins in half until you isolate the one causing the crash. Once you identify it, you can uninstall it or check the plugin maker's website for an updated version.

Check file permissions and try a different format

If the file is on an external drive or network location, Photoshop may not have permission to write to it. Try saving or exporting to your computer's main hard drive instead. If that works, the problem is the file location, not Photoshop. You can then move the file to the external drive after saving.

If you are trying to open a file in an older or unusual format — PSD files from Photoshop 5.0, TIFF files with unusual compression, or proprietary formats from other software — Photoshop may not be able to read it. Try opening the file in the program that created it, then exporting it as a standard JPEG or PNG, and opening that in Photoshop instead. If that works, the original file format is the problem.

Update Photoshop or reinstall if nothing else works

If none of the above steps fix the error, check whether Photoshop needs an update. Go to Photoshop > About Photoshop (Mac) or Help > About Photoshop (Windows) and look for an "Update" button. Install any available updates and restart. Updates often fix bugs that cause this error.

If updating does not help, uninstall Photoshop completely and reinstall it. On Windows, go to Settings > Apps > Apps and Features, find Adobe Photoshop, and click Uninstall. On Mac, drag Photoshop to the Trash and empty it. Then read Photoshop fresh from Adobe's website and install it again. This replaces any corrupted program files that may be causing the error. Your files and settings will not be affected — reinstalling only replaces the program itself.

Frequently Asked Questions

Does this error mean my computer is failing?

No. The error is almost always a software problem — a corrupted file, a plugin conflict, or Photoshop running out of memory — not a hardware failure. If your computer works fine in other programs, the problem is Photoshop or the file you are working with, not your hardware.

Will I lose my work if I get this error?

Not if you save before the error happens. If the error occurs during an operation you have not saved yet, that unsaved work is lost. Photoshop does not auto-save by default. To protect yourself, save your file frequently and turn on auto-recovery in Preferences > File Handling > Auto-Save.

Why does the error happen with one file but not others?

That file is likely corrupted, too large for your current memory settings, or in a format Photoshop struggles with. Try opening it in another program to see if it opens there. If it does not, the file is corrupted and you need a backup or a fresh read.

Can I fix this error without restarting Photoshop?

Sometimes. Clearing the cache without restarting may work, and disabling plugins requires a restart anyway. In most cases, restarting Photoshop is the fastest solution because it clears memory and resets the program's internal state.
