The Edit tab contains tools for modifying text, images, links, and other elements within the PDF. It includes options for cropping, rotating, and resizing objects, as well as adding annotations, signatures, and watermarks.

The View tab provides options for customizing the appearance of the PDF document. You can zoom in and out, rotate pages, and switch between different viewing modes. It also allows you to enable or disable various toolbars and panels.
Format
The Format tab offers tools for adjusting the layout and formatting of the PDF. You can change font styles, sizes, and colors, as well as add headers, footers, and page numbers.

Identifying the Background Lightening Feature
In the toolbar at the top of PDFescape, locate the “Edit” tab. Within the “Edit” tab, you’ll find a dropdown menu titled “Background.” This menu contains the “Lighten Background” feature.
Using the Background Lightening Feature
To lighten the background of a PDF document in PDFescape 2023, follow these steps:
- Open the PDF document in PDFescape.
- Navigate to the “Edit” tab in the toolbar and select the “Background” dropdown menu.
- Click on the “Lighten Background” option.
- In the “Lighten Background” dialog box, adjust the “Lighten” slider to the desired level of lightening. You can preview the changes in the document preview window.
- Click “OK” to apply the changes.
The background lightening feature provides several advanced options for customizing the lightening process. You can choose to lighten the entire background or only specific areas. Additionally, you can adjust the “Threshold” and “Edge Sensitivity” settings to fine-tune the lightening效果.
| Setting | Description |
|---|---|
| Lighten | Adjust the overall lightening intensity. |
| Threshold | Controls the minimum lightness value for pixels to be lightened. |
| Edge Sensitivity | Determines how aggressively the edges of objects are lightened. |
Adjusting Lightening Intensity
Once you’ve selected the areas you want to lighten, you can adjust the lightening intensity using the following steps:
- Click on the “Lighten” button in the toolbar.
- In the “Lightening Intensity” field, enter a value between 0 and 100. The higher the value, the lighter the selected areas will become.
- Click on the “Apply” button to apply the changes.
Fine-Tuning Intensity for Optimal Results
To achieve optimal lightening results, consider the following tips:
- Use the “Eyedropper” tool: Select the “Eyedropper” tool from the toolbar and click on a light area of the document to automatically set the lightening intensity.
- Experiment with values: Start with a low intensity (e.g., 10-20%) and gradually increase it until you reach the desired result. Avoid using extremely high values (e.g., 80-100%), as this can result in an overly washed-out look.
- Preview the changes: Before applying the final changes, click on the “Preview” button in the toolbar to see how the lightening will affect the entire document. This allows you to make adjustments as needed.
Recommended Intensity Values for Common Use Cases
| Use Case | Intensity Range |
|---|---|
| Removing faint stains | 10-20% |
| Lightening dark areas | 30-40% |
| Creating a more uniform background | 50-60% |
| Highlighting important text | 70-80% |
Applying Changes to Entire Document

Use the slider to fine-tune the transparency level and preview the changes in the Sample window.
