Troubleshooting
| Problem | Solution |
|---|
| "File in use" error |
The PDF is open in another program (e.g., Adobe Reader). Close all programs using the file. |
| Image cannot be moved |
Make sure edit mode is active (cursor icon in toolbar). Images can only be moved in edit mode. |
| "Text cannot be copied" |
The PDF contains only images (scanned document). Text was never digitally embedded. Use OCR software. |
| PDF cannot be saved |
Destination folder has no write permissions. Try running as administrator or select a different folder. |
| Program freezes with large PDF |
Very large PDFs (>100 MB, many pages) require a lot of RAM. Close other programs or split the PDF into smaller parts. |
| "Invalid PDF format" |
The file is damaged or not a real PDF. Try opening the file in another PDF reader. |
| Image quality poor after insertion |
The image is not recompressed. If the original has low resolution, it stays that way. Use high-resolution images. |
