Jupyter Notebook Clear Output - Free Online Tool & Easy Shortcuts

Clear outputs from Jupyter Notebook IPYNB files online

Clean your Jupyter Notebook (.ipynb) files by removing all cell outputs (jupyter notebook remove output) and resetting the execution_count. Works entirely in your browser - no upload required. Great for better version control and smaller file size.

Keyboard Shortcut to Clear Output in Jupyter Notebook

If you're looking for a quick way to clear output jupyter notebook, here are your best options:

Tip: In JupyterLab, define your own shortcut under Settings → Advanced Settings → Keyboard Shortcuts.

No built-in standard shortcut exists for ipynb clear output. Use the menus or set your own.

Clear Output Jupyter Notebook - Free Online Tool for ipynb clear output

Upload Your Notebook Files

Output format: cleaned .ipynb  |  Max total size: 20 MB  |  Multiple files supported - ideal for mass jupyter notebook clear output tasks.
All processing happens in your browser - privacy guaranteed by the ipynb clear output engine.

How to Use the Tool (Step-by-Step)

Step 1: Select one or more .ipynb files using the upload field above. This tool helps you jupyter notebook remove output without any uploads.

Step 2: Click Clear Outputs. The tool will remove all cell outputs and reset each execution_count - effectively performing a jupyter clear cell output or jupyter nbconvert clear output process.

Step 3: After processing, the cleaned notebook files download automatically to your device - perfect for clean Git commits and minimal diffs.

Clear Output in Jupyter Notebook (no shortcut required)

Classic Notebook

In the classic Jupyter Notebook interface, you can remove outputs by selecting Cell › All Output › Clear. To both restart the kernel and clear outputs choose Kernel › Restart and Clear Output - a full jupyter notebook clear output workflow.

JupyterLab

In JupyterLab, use the menu: Edit › Clear All Outputs. Alternatively open the Command Palette and run Clear All Outputs. This approach is ideal when you need to jupyter clear cell output across multiple cells.

Clear Output in VS Code Jupyter Notebooks

In Visual Studio Code, you can clear all notebook outputs by opening the Command Palette and running “Notebook: Clear All Outputs”. This effectively performs the ipynb clear output process before committing your code.

If you only want to clear a single cell, open the menu next to the cell and select Clear Outputs. Many users adopt this step as part of their clean commit strategy to avoid large diffs when they jupyter notebook remove output.

For consistent version control, clear all outputs before saving or committing your notebook - this keeps your Git history clean and avoids unnecessary noise.

Clear Output via Command Line (nbconvert)

You can clear notebook outputs directly from the command line using Jupyter nbconvert. This is quick, works locally, and keeps your files clean.

Single file (in-place)

 jupyter nbconvert --clear-output --inplace path/to/notebook.ipynb

Older version (compatibility)

 jupyter nbconvert --ClearOutputPreprocessor.enabled=True --inplace path/to/notebook.ipynb

Batch processing (multiple files)

 for f in *.ipynb; do jupyter nbconvert --clear-output --inplace "$f"; done

Perfect for automation, CI pipelines, or Git pre-commit hooks.

Fully Clear Jupyter Cache & Kernel for Clean Notebook Output

  • Restart the kernel: Kernel → Restart (Classic) or Kernel → Restart Kernel (JupyterLab).
  • Clear variables/namespace (IPython): %reset -f.
  • Remove checkpoints: delete the .ipynb_checkpoints folder (optional).
  • Outputs vs. Kernel: Clearing outputs only removes cell results. Variables stay until restart or %reset - so for full jupyter notebook clear output behaviour, restart too.

FAQ - jupyter notebook clear output & ipynb clear output

Does “Clear Output” also remove my cells?

No. It only removes outputs and resets the execution_count. Code and Markdown cells remain unchanged.

Why do my Git diffs look so large?

Output cells can contain binary or extensive data. Using ipynb clear output or performing a clear output jupyter notebook action greatly reduces diff size and improves review workflow.

Is the tool safe to use?

Yes. Everything runs locally in your browser - no upload, no data transfer.

What’s the difference between “Clear All Outputs” and “Restart & Clear Output”?

“Clear All Outputs” removes outputs only. “Restart & Clear Output” also restarts the kernel - a complete jupyter notebook clear output cycle.

Can I define a keyboard shortcut?

In JupyterLab: Settings → Advanced Settings → Keyboard Shortcuts → search for “Clear All Outputs” and assign your shortcut.
