How to Fix "Sketch Performance Lagging While Working on Large Files"

Working with large files in Sketch can cause significant performance issues, including slowdowns and lag.

To fix these issues, start by optimizing your file.

If your file contains many high-resolution images or vectors, consider reducing the resolution or size of the images.

Sketch allows you to use Image Compression plugins that can optimize file sizes without compromising too much on quality.

Another helpful tip is to convert complex vector shapes into simpler ones by flattening unnecessary layers or paths.

This reduces the number of anchor points Sketch needs to process, speeding up performance.

If the problem persists, check your system’s resources.

Ensure you have enough available memory (RAM) by closing other applications that may be consuming system resources.

If your file contains numerous symbols or shared styles, try flattening those into simple layers to minimize the load on Sketch’s rendering engine.

You can do this by selecting the elements and choosing Flatten Selection from the Layer menu.

Sketch may also struggle with large files if you’re using too many artboards or pages.

Try splitting your file into smaller files, each containing a smaller number of artboards or elements.

This not only reduces the load on Sketch but also makes it easier to manage your assets.

Additionally, if you’re using Sketch on a Mac with limited storage space, consider using an external drive for larger files.

Lastly, enabling GPU rendering in Sketch’s preferences can help improve performance if your system supports it.

If you’re still experiencing lag, consider using Sketch in Low-Resolution Mode, which sacrifices visual quality for performance.

If none of these steps resolve the lagging issue, it might be worth reinstalling Sketch or clearing out temporary caches that might be clogging up the application.
