The Convert to Images tool renders PDF pages as raster images, replacing the original vector content and text with a flat image on each page. This is a secondary safeguard that ensures no extractable text or hidden content remains after redaction.
| Option | Description |
|---|---|
| Page Range | Convert all pages or specify a From / To range. |
| Resolution (DPI) | The dots-per-inch resolution of the raster image. Higher DPI produces sharper images but larger file sizes. Select from preset values in the dropdown (common choices: 150, 200, 300 DPI). |
| Black & White | When enabled, pages are rendered as monochrome (1-bit) images. This produces the smallest file size but loses all color information. |
| DPI | Quality | Use Case |
|---|---|---|
| 72–100 | Screen quality | Quick preview, on-screen viewing only. |
| 150 | Draft print | Good balance of file size and readability for most documents. |
| 200 | Standard print | Suitable for documents that will be printed at normal quality. |
| 300 | High quality | Archival quality, fine detail preservation. Recommended for legal documents. |
| 600 | Very high quality | Maximum detail retention. Produces large files. |
Tip
For redacted documents, 200–300 DPI is usually sufficient. This provides readable output while ensuring that no text layer remains searchable or extractable.
Converting to images is typically the final step in a high-security redaction workflow:
Warning
Converting to images permanently removes all text, form fields, and interactive content from the affected pages. The resulting pages contain only a raster image and cannot be searched or have text selected. This operation cannot be undone.
Note
Converting to images significantly increases file size compared to vector PDF content, especially at higher DPI settings. Consider the trade-off between security and file size for your use case.
