How to Use Scan2PDF to Batch-Convert Scans into PDFs
Overview
Scan2PDF lets you convert multiple scanned images into a single or multiple PDF files quickly. Below is a concise, step-by-step workflow assuming default settings so you can batch-convert efficiently.
What you need
- A scanner (flatbed or sheet-fed) or a folder of scanned image files (JPEG, PNG, TIFF).
- Scan2PDF installed on your computer.
- Optional: OCR module if you want searchable text.
Step-by-step batch workflow
- Prepare scans
- Place all pages in the scanner feeder or gather image files in one folder.
- Open Scan2PDF
- Launch the application and choose the batch or multi-file mode.
- Select source
- If scanning: choose your scanner and set Automatic Feed (ADF) or Multiple Scans.
- If using files: choose “Import folder” or “Add files” and select the folder containing images.
- Set page order and rotation
- Use preview to reorder pages, rotate any upside-down pages, and delete unwanted pages.
- Adjust scan settings (if scanning)
- Resolution: 300 dpi for text, 200 dpi for drafts, 600 dpi for high-detail.
- Color mode: Grayscale for text, Color for images.
- File format: TIFF or PNG if you plan to OCR; JPG for smaller files (less ideal for OCR).
- Apply OCR (optional)
- Enable OCR and select language(s). Choose “Searchable PDF” or “PDF with invisible text” output.
- Choose output options
- Single PDF vs. one PDF per scan: select “Combine into single PDF” for one file.
- Compression: set image compression/quality to balance size vs. clarity.
- Metadata: add title/author/keywords if desired.
- Set destination and filename
- Choose output folder and a naming pattern (e.g., ProjectName_YYYYMMDD).
- Run batch conversion
- Click “Start” or “Convert.” Monitor progress and address any errors (paper jams, unreadable pages).
- Verify results
- Open the resulting PDF(s), check page order, image quality, and OCR text accuracy. Re-run OCR or rescans for problem pages if needed.
Troubleshooting tips
- If OCR fails or is inaccurate, increase resolution to 300–400 dpi and ensure correct language selected.
- For large batches, split into smaller jobs to reduce memory usage and processing time.
- If file sizes are too large, enable stronger compression or downsample images to 200–300 dpi.
Quick presets (recommended)
- Text documents: 300 dpi, Grayscale, OCR enabled, Combine into single PDF.
- Mixed text/images: 300 dpi, Color, OCR enabled, Moderate compression.
- High-quality images: 600 dpi, Color, OCR disabled, Minimal compression.
