CapCut export stuck at 99% is a common issue, especially on low-end PCs with 4GB RAM or less. I experienced this problem myself while exporting a 4-minute video (around 300MB) on an old laptop with an Intel i3 processor and 4GB RAM.

After testing multiple fixes, a few simple changes worked reliably. This guide focuses on practical solutions that actually help low-spec devices.

Why CapCut Export Gets Stuck at 99%

On low-end systems, CapCut often struggles during the final rendering stage. The most common causes include:

• Limited RAM or CPU power

• High export resolution or frame rate

• Background apps consuming memory

• Corrupted or overloaded cache files

The final 1% is the most demanding part of the export process.

Fix #1: Lower CapCut Export Settings

This is the most effective fix.

Recommended settings for low-end PCs (based on my own testing):

• Resolution: 720p

• Frame rate: 30 FPS

• Codec: H.264

• Bitrate: Default or Low

In my case, changing the resolution from 1080p to 720p solved the issue immediately. Export time dropped significantly, and the process finally completed without freezing.

Fix #2: Clear CapCut Cache

CapCut stores temporary files that can break the export process over time.

Steps:

1. Open your CapCut apps

2. Then find Settings tab

3. after that Click Clear Cache

4. and Restart the CapCut apps

This helps free memory and removes corrupted temp files.

Fix #3: Close Background Applications

Before exporting, try to close any application that still running,like:

• Web browsers crhome or other

• Screen recorders

• Game launchers

• Antivirus scans (temporarily), this is the one that uses the most RAM

Low-end PCs need all available RAM during rendering. I also noticed when doing export, keeping the Chrome still running, it most caused  export will be fail.

Fix #4: Update or Reinstall CapCut

If the your problem still continue, try to:

• Check the update, try to get latest CapCut version

• or Reinstall your CapCut

we find out, that's outdated versions more oft contain export bugs that can be affect low-spec systems.

Final Thoughts

CapCut is a powerful editor, but it is not optimized for low-end PCs. For basic edits it works fine, but once projects get longer or heavier, limitations start to show. With the right export settings and a clean system, it can still work.

If your laptop struggles often, switching to a lightweight editor may save you time and frustration.
