Illustrator Error — Not Enough Memory

What Does This Error Mean?

Illustrator is telling you it ran out of working memory (RAM) to complete the task you asked it to do. This often happens with very large or complex files, many open documents, or when too many other apps are running at the same time. The fix usually involves closing things you do not need and giving Illustrator more room to work.

Affected Models

Adobe Illustrator CC
Adobe Illustrator CS5
Adobe Illustrator CS6
Adobe Illustrator 2022
Adobe Illustrator 2023
Adobe Illustrator 2024

Common Causes

The file is very large or complex with many paths, effects, or linked images
Too many applications are open and consuming RAM
Illustrator's memory allocation is too low for the task
Your system has limited RAM (8 GB or less) for design work
Many high-resolution linked images are being used in the document

How to Fix It

Close all other applications — browsers, email, music players, and any other Adobe apps. Restart Illustrator and try again.

Other apps compete for RAM. Closing them frees up memory for Illustrator.
In Illustrator, go to Edit > Preferences > Performance. Enable GPU Performance if it is not already on. This offloads some work to your graphics card.

GPU acceleration reduces how much RAM Illustrator needs for rendering.
Flatten transparency in your document. Go to Object > Flatten Transparency. Use medium or high settings.

Complex transparency effects are extremely memory-intensive. Flattening them simplifies the document.
Reduce the number of open Illustrator documents. Close any files you are not actively working on.

Each open document uses a chunk of memory. Keeping only one or two open at a time helps significantly.
Rasterize complex effects before working with them. Select the object, go to Object > Rasterize. Set resolution to Screen (72 ppi) for working, and re-rasterize at print resolution when done.

Vector effects like blurs and complex gradients use far more memory than rasterized equivalents.

When to Call a Professional

If you consistently hit memory limits with files you need to work on, consider upgrading your RAM. A computer repair shop can advise on compatible RAM upgrades for your machine. Adobe also offers support for optimizing Illustrator performance.

Frequently Asked Questions

How much RAM does Illustrator actually need?

Adobe recommends a minimum of 8 GB RAM, but 16 GB or more is better for complex work. If you regularly work with large files, 32 GB makes a noticeable difference. Illustrator on its own can use 4–8 GB for demanding documents.

Does increasing virtual memory (page file) help?

It can act as a buffer, but it is much slower than real RAM. Increasing virtual memory on Windows may stop the crash, but Illustrator will feel sluggish. It is a temporary workaround, not a real fix.

Why does Illustrator use more memory than Photoshop for similar tasks?

Illustrator keeps every vector path calculation in memory at all times so it can re-render them instantly when you zoom. Photoshop works with pixels, which are simpler to manage. Highly complex vector art can need a surprising amount of RAM.
